31st - A very warm day - the day of the Aiglon College Triathlon, which I could not run because of illness. Yesterday was also extraordinarily hot. A single small tortoiseshell flew near the New Sporting, at the start of the cross-country skiing section o the race. I searched for more but found none. I suspect it had been hibernating in a building.
No butterflies!
10th - Sunday - the day of the Engadine Skimarathon. Saw a peacock flying in the kit collection area at the end of the race and then a further three before I was in the train back home.
11th-14th - individual small tortoiseshells flying around school and at home. One at 8.30am on 11th. Very warm weather gave way to clouds on 14th.
16th - a few small tortoiseshells around, even though not very warm. We have reached the time of year when if the sun comes out, butterflies fly.
17th - warm and sunny - individual small tortoiseshells flying in many places.
25th - the 'bise' has been blowing and it is glacial. But it is also sunny and small tortoiseshells are flying in many places. So far nothing else around here. 28th - still sunny, radiantly warm but ambiently quite chilly. Small tortoiseshells flying.
30th - warm and sunny. Two commas flying in Chesières. A single, male wood white in lower Chesières, in a spring meadow.

1st - trip down to Villeneuve and Les Grangettes. Very few butterflies at all, despite being sunny. But one or two small whites flying over grass and fields and a single male brimstone in Les Grangettes itself. Lots of black kites calling and flying around. Chiff chaffs and blackcaps singing.
2nd - several small tortoiseshells around. Also a few wood whites below Barboleusaz and a single green-veined white also. On return home, a painted lady flew past.
4th - walk in Lower Chesières. Quite windy, so few butterflies. But in sheltered spots plenty of small tortoiseshells and wood whites. One fritillary flying. Very small and tatty - I presumed it to be a small Queen of Spain until a slightly closer view suggested violet fritillary. But I never got close and it disappeared before I could name it definitively.
5th - back in England. New butterflies for the year were orange tip and large white. For various reasons I haven't got a picture of large white on this site - so must procure one asap.
21st - Switzerland - nothing new, but orange tips, wood whites &c. on the wing again after a spell of cold weather
25th - fine weather again in morning - wood whites and work.

2nd - Fine weather. Trip to Chesières, where saw little in general, but one or two violet fritillaries and a pale clouded yellow. Plenty of wood whites and orange tips. No skippers on the wing yet.
9th - Mostly fine weather. A single small heath flying at school. Still far too much work to do to go out looking for butterflies.
13th - Quick trip to Chesières at end of afternoon. Little flying, and no skippers yet, but sooty copper (males only) quite common in sunny meadow and green hairstreak at top of meadow near woods.
16th - Warm sunny day - hottest of year so far. Little blue flying on grassy bank at Aiglon.
[mid-May] - found a dying Berger's pale clouded yellow, a male, by the side of a road. These butterflies are normally too difficult to identify but this was a gift, except to the butterfly.
30th - Quick dash to Chesières during afternoon produced Duke of Burgundy, chequered skipper and large wall, in addition to a very few other butterflies, already noted.

1st - Woodland ringlet, mazarine blue and chequered skippers in garden, as well as common blues. Large wall and a largish fritillary flying around. Swallowtail 'hilltopping' at Les Chaux, but very few other species apart from small tortoiseshell up there. Wood white still in garden.
