Gazoryctra pulcher
Gazoryctra pulcher is a moth species in the family Hepialidae, a group commonly known as ghost moths or swift moths. It is known from the southwestern United States, with records from Colorado, New Mexico, and Utah. The species was described by Augustus Radcliffe Grote in 1865. Like other hepialid moths, it likely exhibits primitive moth characteristics including reduced mouthparts in adults.
Gazoryctra roseicaput
Gazoryctra roseicaput is a hepialid moth described in 1893 from western North American mountain regions. Adults are medium-small with distinctive dull red-brown forewings marked by silvery-white spots. The species has a narrow seasonal flight period in late summer.
Hepialoidea
Ghost Moths, Swift Moths
Hepialoidea is a superfamily of moths comprising over 650 species in approximately 70 genera, commonly known as ghost moths and swift moths. The group is characterized by primitive morphological features including a regressed haustellum (reduced proboscis), short antennae, and distinctive wing venation with a displaced Rs3 vein. Hepialoidea has a cosmopolitan distribution except for Madagascar and Antarctica, with greatest diversity in the Southern Hemisphere, particularly southern South America, southern Africa, and the Australian region. The superfamily includes several families, with Hepialidae being the most species-rich; fossil evidence suggests an origin in the mid-Jurassic with Hepialidae diverging by the mid-Cretaceous approximately 95 million years ago.
Korscheltellus gracilis
Conifer Swift Moth
Korscheltellus gracilis, the Conifer Swift Moth, is a hepialid moth native to eastern and central North America. Adults are active at dusk and exhibit a primitive mating system where males form aerial lek swarms to attract females. Larvae are root-feeders primarily associated with coniferous trees, particularly balsam fir and red spruce, though they can survive on deciduous hosts. The species is considered a forest pest due to larval damage to tree roots and associated pathogen entry points.
Korscheltellus lupulina
Common Swift Moth
Korscheltellus lupulina, commonly known as the Common Swift Moth, is a hepialid moth native to Europe and parts of northern Asia. It was previously classified in the genus Hepialus but was moved to Korscheltellus based on morphological and phylogenetic studies. The species is frequently observed and often abundant across its range. It is one of several swift moth species characterized by rapid, darting flight patterns and reduced mouthparts in the adult stage.
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.
Phymatopus behrensii
Phymatopus behrensii is a hepialid moth described by Stretch in 1872. It is known from California and Washington in the western United States. The species has a wingspan of approximately 43 mm. Larvae have been recorded feeding on a diverse range of plants including Helenium, Lupinus, Malus, and various ferns.
