• Euhagena

  Euhagena is a genus of clearwing moths in the family Sesiidae, characterized by wasp-mimicking appearance and diurnal activity. The genus contains seven described species distributed across North America and parts of Eurasia. Members exhibit sexual dimorphism, with males possessing highly bipectinate (feathery) antennae and distinctive thoracic tufts. These moths are rarely attracted to light and are typically encountered by chance observation or through the use of pheromone lures.

• Knowltonia

  Burnleafs

  Knowltonia is a genus of jewel beetles (family Buprestidae) in western North America. The genus contains four species characterized by extreme sexual dimorphism in antennae: males possess highly modified, bipectinate (biflabellate) antennae with dual projections from terminal antennomeres, while females retain unmodified serrate antennae. This antennal modification is presumed to function in detecting female sex pheromones. The genus is notable for its independent evolution of male antennal elaboration similar to that seen in the tribe Xenorhipidini and other disparate buprestid taxa.

• Lasiocampidae

  Lappet Moths, Eggars, Tent Caterpillars, Snout Moths

  Lasiocampidae is a family of moths comprising over 2,000 species worldwide, representing approximately 5% of global moth diversity. The family is characterized by large, hairy caterpillars with distinctive skin flaps on their prolegs, and adults that are typically large-bodied with broad wings. Many species are notable for their social larval behavior, including tent caterpillars that construct communal silk nests. The family is the sole member of the superfamily Lasiocampoidea and includes several economically significant forest pests.
