Phymatopus
swift moths, ghost moths
Phymatopus is a genus of swift moths in the family Hepialidae, erected by Wallengren in 1869. The genus occurs across Eurasia and western North America, with species distinguished primarily by male genitalia morphology and forewing pattern variation. Members lack tibial spurs, proboscis, frenulum, and have very short antennae. The genus exhibits an unusual mating system where males release attractants to draw females, reversing the ancestral hepialid condition.
