Commentary (Links in the
commentary are to pictures of the particular butterflies referred to)
Began the new year in Suffolk, UK. It rained much of today and
butterflies were definitely off the menu. Here are some dunlin feeding on the mudflats and here some turnstone on the sea wall in Woodbridge.
11th: It has been very cold and, more recently, snowy in Switzerland. This picture was taken at 22h00 this evening, under a nearly full moon.
13th: Another evening photo, with heavy snow falling.
14th: Still heavy snow. No possibility of butterflies.
15th: A buzzard circling in the mountains.
21st: Forecast temperatures at Martigny were for a minimum of – 8°C before dawn to a maximum of – 1°C
during the afternoon. Despite that, I went to look for Queen of Spain
fritillaries, as it was also forecast to be a lovely day. I set off
late, arriving at my first hotspot shortly after midday. Within a
minute of my arriving, a male Queen of Spain flipped up from the
vineyards, spun over the path, flashing silver as it went, checked out
the sunny bank and flew on. I waited a further 15 minutes there but no
more appeared. This
is the location. Then I checked my other hotspots, without success.
Finally, from 13h00 to 13h30 I waited at the first hotspot, still
without seeing any more. By this time, the chilly breeze that had
prevented the earlier Queen settling was stronger and it felt
intrinsically unlikely any more Queens would appear. I saw no lizards
and just a handful of flies during the walk.
29th: Another trip to the valley on a sunny day. This time, although I still (probably) only saw one Queen of Spain, I was able to photograph it. Here is another shot. The ambient temperature was about – 3° but it felt warmer in the sun. In some places there was lots of snow, in others it had mostly melted. The only other butterfly I saw was this red admiral, my first of the year.
2nd: The Föhn was blowing today. At lunchtime I saw a single small tortoiseshell fly past my house.
11th: Sunny in the Rhône Valley with hazy cloud increasing during the
day. My first Queen of Spain hotspot was quite windy and I saw just one
there, which checked out the exposed rock but didn't want to settle. My
next hotspot was well shaded and I photographed four different
individuals (here, here, here and here), probably seeing more in total. Here is a shot with two individuals basking not far from one another and here is an underside. No other butterflies were on the wing. I came back via the first hotspot, again seeing a single Queen of Spain, and then the Bulbocodium
fields. These were already in flower but no small tortoiseshells were
nectaring on them. A few bees were visiting them. Otherwise, firebugs
and lizards were to be seen on the walk; but there are no real signs
yet of the beginning of the season.
13th: Sunny in the mountains and a little hazy in the valley. No
butterflies were on the wing in Huémoz (I expected the odd small
tortoiseshell) but at a wintering hotspot a little lower down I found a
couple of red admirals zooming around, defending territories. They were
rarely basking and I only got this one, record shot. Nearby I found this brown hairstreak egg.
15th: Arrived by bus in Santander, Cantabria (Spain), this morning. On a sunny bank in town I found a speckled wood (and here)
sunning itself and nectaring at about 10h00. I found at least two more
at the same site later in the day, when large and small whites were
also zooming around, very seldom stopping. Elsewhere, in an urban park,
I saw two peacocks, and during the day spotted at least three red admirals in flight.
16th: Met my sister off the ferry from Portsmouth at 14h15, for drive
south to Córdoba but had time in morning to look for a few butterflies
in town. Saw some of the same as yesterday, including several speckled woods (and here), lots of small whites and a few red admirals (and here).
17th: Day in Córdoba. I saw a few whites here and there but we didn't
leave town or visit any real green spaces. It is a lovely, old town.
18th: Left for Málaga on the earliest bus, which unfortunately didn't
get me there until 11h15. On the way south the weather seemed to get
worse and worse, with thickening cloud and mist, but suddenly as we
approached Málaga itself everything cleared and it was hot when we
arrived. I began my butterfly search by looking for African grass
blues. It seems too early still for this, as I found none despite
thorough searching (on my way back, too). But I did see a couple of geranium bronzes (and here) in the usual grass blue sites. Then suddenly a pair of monarchs
gliding majestically high up caught my eye. One landed very briefly and
I got a record shot but I didn't get any half decent shots until I came
back the same way later in the day. here, here and here
are three shots of the same monarch. In total I saw eight of them,
including one mating pair in flight. Apart from the one, none were
interested in posing for pictures and even that one was not very
cooperative! I saw my first of many clouded yellow
in the same place - these were reasonably frequent all day. I left the
town and headed for the hills, photographing this presumed female Polyommatus celina - presumed because I am fairly confident this is a male celina and they were at the same place. Later I photographed this underside, which might also be celina - I'm not sure if icarus flies here too. As I climbed up towards my hilltopping site I got this record shot of a Bath white and my first Spanish festoon of the day. I saw about three festoons in total. Hilltopping were red admirals, painted ladies, green-striped whites, western dappled whites, long-tailed blues, walls, swallowtails and southern scarce swallowtails (and here).
I saw a single small tortoiseshell heading off down the hill. Leaving
the hilltoppers, which were so active it was almost impossible to
photograph them, I set off to look for Provence hairstreak. I wasn't
sure if this would be on the wing here yet but was delighted to find at
least two individuals - here and here. All in all, it was a wonderful day in the hills, capped by the monarchs in town.
23rd: A few small tortoiseshells drifting around Huémoz banks during my short, mid-morning walk.
25th: Very cold in the mountains but sunny, with snow still on the
roads. I waited until 11h00 to cycle down the hill, but even then it
was freezing on the hands. In my usual wintering spots in the valley
about half a dozen Queen of Spain fritillaries were flying, upwards of 20 small tortoiseshells and a couple of red admirals.
26th: Sunny in Huémoz for much of the day, with episodes of clouds.
Small tortoiseshells were flying freely over all the grassy areas.
March 2nd: Small tortoiseshells were on the wing in Huémoz.
5th-7th: Heavy snow returned.
10th: Peacock flying over the meadows near my house after school.
12th: Last year on 12th March I set off along the Rhône Valley in
search of large tortoiseshells. Then, I found none at my first site so
headed further east in the afternoon to a second site, where I found
the species. So today I headed directly for the second site, arriving
at about 11h00. No large tortoiseshells. In fact, no butterflies at all
except a handful of brimstones doing circuits along a track and up a
hillside. Here is a grey wagtail by the water. In the afternoon I went back to last year's first site and soon found my first large tortoiseshell (and here).
This one didn't bask at all, but further along I found several more -
at least 4 in total but probably more - some of which were prepared to open up (and here) The problem was, they were constantly being harassed by the many small tortoiseshells at the site. Small tortoiseshells and brimstones were nectaring on sallow catkins (and here, and here with a passenger).
There were lots of brimstones - usually several nectaring on the same
tree at once and always one or two roding along the track. Other
species seen were a couple of Queen of Spain fritillaries, several commas and a single eastern Bath white, Pontia edusa.
I left before 15h00 because I had a lot of work to do back home. As I
left, things were apparently beginning to hot up. Roll on the clock
13th: After a cloudy start it was a warm day. Although I had to spend
it working I did see several small tortoiseshells on my lunchtime
14th: Warm again - small tortoiseshells flying.
15th: Intermittently cloudy and sunny. I saw three brimstones as I
cycled into school at lunchtime, as well as one each of small
tortoiseshell and red admiral during the day.
16th-17th: Sunny. Small tortoiseshells in Huémoz and a few brimstones seen as I cycled into work on both days.
19th: Mostly cloudy. This is (I believe) the remains of a silver-washed fritillary pupa (and here),
found on honeysuckle while looking for white admiral caterpillars. The
honeysuckle is coming into leaf throughout the wood. Here is a white admiral caterpillar, probably on his first sortie outside the hibernaculum.
25th: Up early and off to Italy, arriving at Domodossola shortly after
10h00, in the hope of nettle tree butterflies, green hairstreaks and
maybe chequered blues. Despite a good forecast, it was in fact cloudy
almost all day, with sunny intervals of a few minutes at a time. As I
cycled to my first nettle tree spot I saw brimstones and small whites.
At the site, I initially saw only large tortoiseshells, flying despite
the cloud - this was the commonest species of the day (a large tortoiseshell from my second site). Then a first holly blue put in an appearance, then a wall, and then finally I spotted this nettle tree butterfly in a nettle tree, sihouetted agains the sky. Suddenly, the sun came out and I got this shot
with the light coming through. Throughout the rest of the day I saw
nettle-tree butterflies here and there in the brief sunny intervals.
There were no good photo opportunities but here, here and here are some more shots. Green hairstreaks (and here, and here)
were also flying in the sunny spells, disappearing as if by magic when
the clouds came over. The full species list was: small white,
brimstone, orange tip, wood white, small copper,
green hairstreak, holly blue, nettle-tree butterfly, large
tortoiseshell, Camberwell beauty (I put up the same individual twice
during a long cloudy spell but never saw where it landed) small
tortoiseshell, peacock, comma, wall.
27th: Small tortoiseshells flying around Huémoz.
29th: Working in morning but cycled down to valley in afternoon.
Southern small whites are now flying, as well as small whites and
green-veined whites - here are both species in one picture. Southern grizzled skippers are now on the wing (and here).
Also seen were: brimstone, orange tip, holly blue, comma, small
tortoiseshell, large tortoiseshell, peacock, Queen of Spain and
30th: I had time after school to check the woods, now the evenings are
lighter. Some of the sallow is in leaf so I scanned for any first signs
of purple emperor feeding. High up one, some 7-8m off the ground, I
spotted this clump of nibbled leaves with a caterpillar
resting on his seat leaf. I named him Kyle (South Park characters for
the 2016-7 season!). He's not going to be easy to follow, at that
height, but I hope to find more before long.
31st: A trip to the valley, where despite haze and a strong wind I was able to find 21 species: swallowtail and scarce swallowtail, small, green-veined, eastern Bath and wood whites, orange tip (and here, rudely intruding on a pair of mating beetles), brimstone, clouded yellow, green hairstreak, holly blue, Queen of Spain (and here), comma, large tortoiseshell (and here, a different individual), small tortoiseshell, peacock, Camberwell beauty, red admiral, speckled wood, dingy skipper and grizzled skipper.
Probably the commonest butterfly of the day was orange tip, though I
saw no females. Large tortoiseshells are common too, and I saw
Camberwell beauties at both sites I visited. In the morning, eastern
Bath whites were zooming around non-stop while the weather was still
reasonably good. By mid-afternoon it was predominantly overcast and by
16h00 I headed home.
1st: Grizzled skipper (malvae, rather than malvoides) in my local woods. Here is a slightly better picture of Kyle, the purple emperor caterpillar, than I was able to get the other day.
3rd: A trip to the valley. New for the year were violet fritillary and baton blue.
There were quite a lot of violet fritillaries about and at least three
baton blues. I also saw a single Berger's clouded yellow and a single
de Prunner's ringlet, both year firsts. Neither stopped for a picture.
I was surprised not to find any chequered blues yet, nor mallow
skippers. Other species flying were: swallowtail, scarce swallowtail,
small white, green-veined white, southern small white, wood white,
eastern Bath white, orange tip, brimstone, clouded yellow, holly blue, green hairstreak, small tortoiseshell, large tortoiseshell, Camberwell beauty, peacock, comma, speckled wood, southern grizzled skipper, dingy skipper. 4th: Found a second purple emperor caterpillar,
in a part of the woods I regularly search but where I have never found
one before. I have called him Mr Mackey. Although I didn't even touch
the branch and did my best not to disturb him, he stopped feeding and
retreated to his resting position when he became aware of me. 6th-7th: Back in Suffolk, in the UK, the weather is mild and butterflies are on the wing. Today and yesterday I saw plenty of orange tips in the garden, male and female (and here),
as well as a few holly blues, commas, peacocks and a brimstone. Today
the first small white drifted through. Yesterday, on a cycle ride to
the coast, I also saw red admiral, small tortoiseshell and speckled wood. This peacock
was taken on blackthorn in local woods. I was surprised not to see any
small coppers but I am sure they will be on the wing any day now. 8th: An evening trip to local woods. Lots of commas (and here) and peacocks (and here) were sparring for the best sunspots. 9th:
Had a quick look in the morning to see if any green hairstreaks had
emerged yet. I didn't see any. Orange tips are everywhere, as well as
commas, peacocks and now a few small whites too. Holly blues are easy
to find but so far I have not seen one settle. Here is a blue tit. 11th: A holly blue in our Suffolk garden (and here).
18th: Back in Switzerland, here is Mr Mackey,
now in his 4th instar. If he keeps going at this rate he will be flying
in early to mid-June! But it's much colder now so things might well
slow down. Here is a new caterpillar I found this evening - Timmy (and here). It was too dark to find Kyle by the time I got there.
21st: It has been sunny but very cold for the last few days. Today at
lunchtime a Berger's clouded yellow was flying, as well as this green-veined white and a few small heaths, new for the year.
22nd: First trip to the Rhône Valley since my return to Switzerland.
Almost as soon as I got out of the train I saw my first green-underside
blue of the year, closely followed by my first Adonis blue. Unsurprisingly, many firsts for the year followed: Chapman's blue (locally very common), turquoise blue (just this pair, which I first spotted courting and here), Provençal short-tailed blue (a few), Osiris blue (locally common), Glanville fritillary (generally common), spotted fritillary (locally common), pearl-bordered fritillary (just one seen), rosy grizzled skipper, safflower skipper. Hibernators are still on the wing, with Camberwell beauty (and here),
comma, large tortoiseshell, small tortoiseshell, brimstone and peacock
all out in reasonable numbers. The full list for the day was: scarce swallowtail,
small white, green-veined white, southern small white, eastern Bath
white, orange tip, wood white, brimstone, Berger's clouded yellow,
green hairstreak (small numbers everywhere), small copper
(surprisingly, just a couple), green-underside blue, holly blue, Adonis blue, Chapman's blue, turquoise blue, baton blue,
Provençal short-tailed blue, Queen of Spain fritillary, pearl-bordered
fritillary, Glanville fritillary, spotted fritillary, large
tortoiseshell, small tortoiseshell, peacock, comma, Camberwell beauty,
red admiral, speckled wood, wall, de Prunner's ringlet, small heath, southern grizzled skipper, rosy grizzled skipper, safflower skipper, dingy skipper.
23rd: I had to be at a meeting in Montreux until after 13h00 and was
held up on the train by a signal failure after that, so couldn't get
very far along the Rhône Valley this afternoon. In a vineyard walk I
saw my first little blue
of the year, as well as walls, lots of Glanville fritillaries, Queen of
Spain fritillaries and a few dingy skippers. I then spent about an hour
at a mud patch, watching common blues (my first of the year, as the ones in Spain were celina), turquoise blues, green-underside blues (and here and here), Provençal short-tailed blues (this individual is apparently exuding waste or water from the tip of its abdomen), holly blues, wood whites, scarce swallowtails and a few more Queens of Spain and dingy skippers. It was late in the day but still warm.
29th: After two days of snow it was still very cold this morning. I
cycled down the hill at 09h30 and by the time I reached Aigle my hands
were numb. We headed off to a site in Valais at about 900m, arriving
shortly after 11h00. It was still cold and very little was flying -
some speckled woods and a few roding orange tips. By midday it had
warmed up considerably and during the afternoon more and more took to
the wing. Four species were new for the year: Nickerl's fritillary (a couple of males - here is another shot), Oberthür's grizzled skipper (quite common - and here), chequered skipper (just one seen) and Duke of Burgundy (just that female). Other species were: swallowtail, scarce swallowtail, small white, green-veined white, Eastern Bath white, brimstone, Berger's clouded yellow, small copper, Adonis blue, little blue, Provençal short-tailed blue, holly blue, green-underside blue, Glanville fritillary, Queen of Spain fritillary, pearl-bordered fritillary, comma, large tortoiseshell, peacock, red admiral, small heath, southern grizzled skipper and dingy skipper. Here are a male and female orange tip and here a female rejecting a male's advances.
30th: Worked at home in the morning but cycled to a local 'tails' site
in the afternoon to look for short-tailed blues. There were plenty of Provençal short-tailed blues (this female laying on medick, and here - here is a male) and also common and Chapman's blues, but initially no short-tailed. Sooty coppers were on the wing (and here, and here). Here is a swallowtail and here a scarce swallowtail. Finally, a single, female short-tailed blue flew through, pausing briefly for that photo before moving on, over a hedge and out of the meadow.
May 5th: I am currently following five purple emperor caterpillars, named this
season after South Park characters. I checked on them all today. They
are: Mr Mackey (he has been in fourth instar some weeks and should enter 5th very soon), Timmy (also fourth instar, but a little younger), Wendy (third instar, currently laid up for shedding her skin), Stan (fourth instar for some weeks now - that picture was taken two days ago - here he is today) and Mr Garrison
(fourth instar - that picture also from two days ago - he was still
there today). It was sunny today. Brimstones, orange tips, wood whites,
speckled woods, peacocks and pearl-bordered fritillaries were all
flying in the woods.
9th: Took a trip after school to see if cardinals and iolas blues were
flying yet. It was sunny but windy and late in the day so perhaps not
surprising I saw no cardinals. No iolas blues either. The bladder senna
was not really in flower yet - no more than a few flowers on any bushes
- so I think it is still too early for this species. I did see my first
red-underwing skipper of the year, as well as turquoise blue, common blue, green hairstreak, Provençal short-tailed blue, Adonis blue, holly blue, wood white, Queen of Spain fritillary, wall and safflower skipper.
13th: A trip to the valley for cardinals and Iolas blues. It was sunny when I arrived at my first cardinal site and I saw a single male (and here),
which stayed just long enough for those record shots. As clouds were
brewing I moved to my second site but it was overcast by the time I got
there. At first, all that was flying were a swallowtail,
a turquoise blue, a wood white and a couple of Berger's clouded
yellows. I couldn't find any Iolas blues on the bladder senna. Then, by
a stroke of luck, I found a single, female Iolas blue perched out in the open (and here, and here). Here is an underside shot,
after she moved and settled on some rocks. It was still overcast so I
moved further up the valley to where sun was forecast, visiting two
different sites. Camberwell beauties (and here) are still on the wing, but rather tatty now. This is my first geranium argus of the year. There were no Provençal fritillaries but plenty of Queen of Spain fritillaries and a single Glanville. For the skippers, I saw southern grizzled, safflower and dingy. Eastern Bath whites were common, as were wood whites. Other species were: red admiral, comma, peacock, speckled wood, green-underside blue, turquoise blue, Adonis blue,
Provençal short-tailed blue, common blue, Chapman's blue, swallowtail
and scarce swallowtail. There were a few small heaths over the meadows
and brimstones drifting up and down near the woods.
16th: First properly sunny and warm lunchtime walk for ages. Meadow fritillaries (and here) are now flitting over the meadows, though I only saw males today.
20th: Saw my first black-veined whites of the year while I was looking for ladies' slipper orchids. This geranium argus was roosting in the cold in a local meadow in the morning.
21st: Expedition to Valais for mountain dappled whites. Surprisingly,
although the foodplant was abundant and in full flower, I saw just one dappled white, a female (and here). I imagine they were very early this year - it is
difficult to believe this is the very beginning of the season. I also
saw a single cardinal zooming up the road. This is a considerable
distance from my usual cardinal site and I believe a satellite colony.
Also new for the year were northern wall, olive skipper and Apollo. I
thought I saw Escher's blue but have no proof this. Other species seen
were scarce swallowtail, brimstone, clouded yellow, Berger's clouded
yellow, small white, wood white, orange tip, Glanville fritillary,
Queen of Spain fritillary, wall, speckled wood, small heath, de
Prunner's ringlet (and here), common blue, Chapman's blue, little blue and
22nd: Current state of the purple emperor caterpillars I am following in my local woods.Stan (and here
- both photographs taken today), the most advanced, entered 5th instar
on 12th May.Today he moved from his old seat leaf and relocated to a
new leaf about 4m away. It is too soon for him to be pupating but it is
possible he sees his new site as a possible pupation site. Or, he may
move again in a few days. Mr Mackey
(that picture taken two days ago - he is still there today, on the same
leaf) entered 5th instar on 18th May. Mr Garrison probably entered 5th
instar yesterday. Here he is today. Wendy is still laid up for transition into 5th. I took this rather poor picture today.
25th: All the purple emperor caterpillars have moved and I couldn't
relocate them on today's walk. All ate half their resting leaf - a sign
they intend to travel some distance. Stan almost certainly went off to
pupate. I saw my first large walls of the year.
26th: Worked in the morning but had time in the afternoon to check on the cardinals. They were on fine form. Here, here, here and here are some females and here one of the few shots I got of an uperside. Here, here and here are some males. Good photographs were very difficult because it was so hot and they were very mobile. I also saw about a dozen iolas blues.
These were even more mobile and that was the only photo I got. I saw my
first marbled skipper of the year, as well as red-underwing skippers, a
safflower skipper, various other blues including turquoise, little and
Adonis and lots of Queen of Spain fritillaries.
27th: Trip to Geneva to see if poplar admirals were flying yet. They
weren't - and indeed very little at all was flying at my chosen site. I
did see my first meadow browns
of the year. Apart from that, the species list was: small white,
green-veined white, wood white, Berger's clouded yellow, black-veined
white, speckled wood, comma and chequered skipper.
28th: Another trip to the Canton of Geneva, this time for black
hairstreaks and large coppers. At my first site, black hairstreaks were
quite visible, flitting over the tops of blackthorn thickets or
disappearing deep into them, but almost impossible to photograph. Here
is one, distant shot of the first one I saw. It was a very hot day -
over 30 degrees C - and very little was settling, of any species. At
the same site I also saw my first heath fritillaries and pearly heaths
of the year. I have seen large coppers here in the past but there were
none in evidence today. Moving on to my main large copper site, I
thought at first they were not flying there, either. Then I caught site
of what seemed to be a male, at some distance, but it was not behaving
territorially like most of the males I see. I got a poor, long shot of it. At this site there were also heath fritillaries, and Glanville and knapweed too - and quite a lot of very fresh, summer brood violet fritillaries. As I was preparing to leave, I saw another large copper, this time a female,
and followed her. She was flitting around well away from the water.
Thinking large coppers laid their eggs near water I assumed she wasn't
doing this and wondered what she was doing - stopping for just seconds
at a time and always searching. But soon I had found another three females (and here), and these were definitely laying. Here and here
are some shots of the eggs laid by these females. These are in a hot,
dry field, near a river but not damp in any way. At the same site I saw
grizzled skipper and dingy skipper. Finally, I moved on to get a year
tick for Reverdin's blue. This had obviously been on the wing a while
and I saw just one, very worn individual.
Like large coppers, Reverdin's blues are double brooded and will fly
again in August. Other species seen during the day were comma, speckled
wood, meadow brown, common blue, my first brown arguses of the year, my
first marbled fritillary of the year, swallowtail, brimstone and
