Warren's Skipper
Description:
Warren's Skipper occurs mostly on flower-rich alpine grasslands. The males fly where flowers are most abundant, along mountain streams, for example. From a perch on a bush or tall plant, they also defend their territory. The females meanwhile are often found on warm, dry patches near bushes, where they lay their eggs one by one on the rockroses (Helianthemum spp.), preferring the smaller plants.
The small caterpillar lives hidden in a spun leaf, while caterpillars of later stages spin two leaves together, and finally, make a larger shelter from several leaves.
The Warren's Skipper is single-brooded and passes the winter as a caterpillar.
