Description
Oberthür’s Grizzled Skipper is generally limited to unimproved grasslands. In the north of its range,
the populations are small, but large numbers of butterflies make up the southern populations.
The butterflies can often be seen visiting flowers and seem to be especially fond of Globularia.
The female lays her eggs singly on the underside of the leaves of cinquefoils (Potentilla spp.) and
rockroses (Helianthemum spp.). The caterpillars of the first instar only eat the surface layer, leaving
translucent “windows” in the leaf. The larger caterpillars eat the whole leaf, and live in a tent-like
shelter, spun from one or more leaves. It is the caterpillar that hibernates. It pupates in a cocoon
on the ground and there are two to three generations a year.
