            The below photos were taken by the author in a suburban yard on West Summer Street in Appleton, WI (Outagamie County) (Google Earth figures).  The habitat includes a variety of trees, gardens, and lawns.  The closest forested habitat is along the Fox River about 1.2 miles to the south (mesic to hydric hardwoods).  Fields, mesic to hydric hardwood forest, and prairie planting occur just over 2 miles to the west.  Forested and open wetlands occur just over 3 miles to the northwest.  Xeric uplands do not occur in the vicinity.

 

While many of the photos shown are of live specimens, at least one voucher specimen of each species was collected on each date recorded.  Many of the live specimen photos are the same individuals as the voucher specimens collected after the photo was taken. 

 

I have collected at least twelve species of Nymphulinae in Wisconsin: Chrysendeton imitabilis, Elophila ekthlipsis, Elophila icciusalis, Elophila gyralis, Elophila tinealis, Elophila obliteralis, Paraponyx maculalis, Paraponyx obscuralis, Paraponyx badiusalis, Paraponyx allionealis, Petrophila bifascialis, and Petrophila canadensis.  Eight of these occur in suburban Appleton, and seven were found in numbers every year from 2016-2018.  All of these species have aquatic larvae and no suitable breeding habitat is present in surrounding blocks.  Thus, all of these species are dispersers from their breeding habitat, yet Elophila obliteralis is one of the most common pyralid species here.  In 1995 I found Nymphulinae larvae in abundance in a pond at Memorial Park 2.1 miles northeast of the suburban yard. 

 

Numbers in [ ] are from the Hodges et al. (1983) checklist of the Lepidoptera of America North of Mexico.
