Abstract

The common sooty wing skipper, Pholisora catullus, has three broods each year in east-central Illinois. Adults are active for only a few hours at mid-day_ Wing color is a rough indicator of age in the field, changing from black to brown over 5 days. These skippers have adult lifespans of about 1 week in the field. Females mate early on their first morning of adult life, and some females mate more than once in their lifetime. Females can lay up to 32 eggs daily, and appear to be able to detect host plants visually over a distance of up to one meter. Densities of these insects are lower in and around urban areas even though larval host plants and suitable nectar sources for adults are present.
