Panorpa hungerfordi
Byers, 1973
common scorpionfly
Panorpa hungerfordi is a of in the Panorpidae, described by George Byers in 1973. Like other scorpionflies, it is characterized by the male's enlarged, upward-curved genital claspers that resemble a 's stinger. The species is found in North America and shares the general habits of the : frequent moist woodland where they scavenge on dead or dying insects. Larvae develop in soil and leaf litter, feeding on soft-bodied .

Identification
Panorpa hungerfordi can be distinguished from other Panorpa by examination of male genitalia, specifically the structure of the claspers and associated genitalic characters. As with most scorpionflies, the presence of three complete dark bands across the yellowish wings and the presence of an anal horn on the sixth abdominal in males are useful field characters for distinguishing species within the . Conclusive identification requires microscopic examination of genitalic structures.
Habitat
Moist woodland , particularly dense forests with abundant leaf litter and damp soil. are typically found in shaded, humid microhabitats within forested areas.
Distribution
North America. Specific range details are poorly documented, but the occurs within the broader North American distribution of the Panorpa.
Diet
are scavengers, feeding on dead or dying soft-bodied insects. Larvae feed on dead or dying soft-bodied in soil and leaf litter.
Life Cycle
Complete . Larvae live in soil and leaf litter, passing through four instars before pupating in an earthen chamber. emerge from .
Behavior
are known to scavenge prey from spider webs, a documented in related such as Panorpa acuta. When threatened or disturbed, adults flit nervously through dense foliage to escape. Males use their enlarged claspers to grasp females during mating.
Ecological Role
Scavengers that contribute to nutrient cycling in forest . Their presence on cadavers has been documented in studies, where they may serve as early-arriving indicators in decomposition .
Human Relevance
Has been documented in research as an early visitor to human cadavers, where scorpionflies fed on fluids from autopsy incisions. This may provide useful information for determining postmortem intervals in legal investigations.
