My first ever picture, from Switzerland, taken many years ago!
Apollo is commoner
than the Apollo in my region of the Alps, though in general
it is a scarcer butterfly. I have also seen it in the Pyrenees. It
flies typically in June and July in a shorter flight season than its
cousins, the Apollo and small Apollo.
flight it resembles the black-veined white but is quite distinctive
when seen settled. Black-veined whites lack any black spots on the
wings. Unlike the Apollo and small Apollo, the clouded Apollo lacks any
red, making it equally easy to distinguish from them too. Like all
apollos, it has characteristically
areas at the wing tips, making it less conspicuous at rest than you
This is a
difficult butterfly to
approach closely, being very wary and capable of zooming off a
considerable distance - usually over a steep slope - without any
effort. It does stop frequently, though, and the photographer's best
opportunities are on mixed cloudy/sunny days when advantage can be
taken of the cloudy spells. The larvae feed on various species of Corydalis,
hibernating fully formed in the egg and developing the following
spring. For this reason, the date of its emergence depend strongly on
when the winter snow melts.
