Epargyreus clarus, silver spotted skipper, and the tallgrass prairie plants they were found foraging on at Barnes Prairie remnants, Racine Co., WI from 2020 through 2022
Eparygyrus clarus, silver spotted skipper, is a commonly found on Barnes Prairie, which consists of a number of small tallgrass prairie remnants. According to my observations over the past 50 years, silver spotted skippers have been one of the most abundant butterflies on these remnants. In the last 20 years, as many of these prairie areas have been developed to housing and commercial businesses, the skippers have found new nectar sources on purple clover, Trifolium pratense, queen Ann’s lace, Daucus carota,and teasel, Dipsacus fullonum (D. sylvestrus) flowers.
