The Bad-Wing Moth - Dyspteris abortivaria

Description:

Gunpowder Falls State Park Sweet Air, Sweet Air, MarylandTaken verbatim from BugGuide.net: Called "The Bad-Wing" because the small hindwings are difficult to pull into position for pinning. The name of the genus also means bad wing - from the Greek "dys" (bad, difficult) + "pteron" (wing). Even the specific epithet abortivaria doesn't sound good, perhaps suggesting that various attempts or methods of pinning the wings have been aborted.Host Grapes
