These day-flying tiger moths are on the wing throughout the summer in fields with flowers, where they nectar from goldenrods (Solidago spp.) and more. You may also see them occasionally flying at night, when lights draw them in. Their common name is a bit misleading since the vast majority of individuals have an orange collar rather than yellow. Like other tiger moth larvae, the caterpillars are “hairy.” The caterpillars feed on grasses (Poaceae) and sedges (Cyperaceae). This species is widely distributed in North America, found from coast to coast. BugGuide mentions that the adults are probably Batsian mimics of wasps or perhaps beetles.
Size: Wingspan 30 – 37 mm
