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

Identification
Clearwing moths in this can be distinguished from other sesiids by their combination of -mimicking coloration, reduced wing scaling that creates transparent areas, and the presence of hair-like thoracic . Males are readily identified by their prominently bipectinate and wispy white thoracic tufts. The wings possess flattened marginal scales that are visible upon close examination. Specific identification requires examination of genitalia or detailed pattern analysis.

Distribution
North America and Eurasia. occur in the Great Plains and western regions of North America, with E. nebraskae documented from Kansas, Nebraska, and surrounding areas. Eurasian distribution includes species described from Central Asia.
Behavior
activity with little to no attraction to artificial light sources. Males have been observed perching on elevated vegetation such as dried flower . is pronounced, with males displaying elaborate and thoracic ornamentation. Some exhibit cooperative perching that facilitates photography and observation.
Human Relevance
Of interest to lepidopterists due to their -mimicking appearance and challenging observation. lures have been used successfully to attract males for study, though most encounters remain opportunistic. The serves as an example of hymenopteran mimicry in .
Similar Taxa
- MelittiaBoth are sesiid with -mimicking appearance, but Melittia are generally more robust with different wing venation and lack the highly bipectinate male seen in Euhagena.
- SynanthedonAnother clearwing moth , but Synanthedon are typically smaller, often show different color patterns, and some species are occasionally attracted to lights—unlike Euhagena.
