Courting couple, male on left, female on right. Switzerland.
The orange tip is the spring butterfly par excellence.
As the hedgerows burst into flower, so these delicate and beautiful
insects begin to flit along them, occasionally resting on garlic
mustard or other plants to feed. The males are unmistakeable, even at a
distance, with their brilliant orange tips. The females, though
superficially like other whites, are also easily distinguished if the
mottled underside is seen. The upperside pattern is sufficiently
different, too, for ready identification given a good view.
