Alternate Common Name: European Skipperling.
This skipper occurs in two distinct populations in North America. In the east, it ranges from southeastern Manitoba to Newfoundland and south to northeastern Missouri and Tennessee. In the west, it occurs in British Columbia, Idaho, Montana, and Colorado. Its range is continuing to expand.
It can be found in fields, meadows, pastures, and other grassy places.
Caterpillar: Caterpillars feed on the leaves of timothy (Phleum pratense) and other grasses.
Adult: Butterflies drink nectar from short-stemmed flowers such as clover (Trifolium spp.), milkweed (Asclepias spp.), and thistle (Cirsium spp.).
Eggs overwinter and hatch in the spring. There is one generation of caterpillars each summer. Caterpillars live in nests made of leaves tied with silk. Adults generally fly from mid-May to mid-July. Butterflies roost at night in tall grasses; in some areas, the butterflies have been observed roosting together by the hundreds. A strange and detrimental behavior of some of the butterflies, reported by one expert, is crawling within orchid flowers (Cypripedium spp.) in search of nectar. Once inside the flower, the butterfly is trapped and cannot get out. Interestingly, native skippers have not been observed behaving similarly. The European Skipper was introduced to Ontario, Canada from Europe in 1910 and to British Columbia in 1960, and the species has spread considerably since. Its progressive expansion is believed by experts to be the result of the inadvertent transport of its eggs through the shipment of hay.
Males actively patrol all day among grasses in search of receptive females. Strings of eggs are laid on the stems of grasses.
