Panorpa setifera
Webb, 1974
common scorpionfly
Panorpa setifera is a of in the Panorpidae, described by Webb in 1974. It belongs to the order Mecoptera, commonly known as scorpionflies due to the enlarged, upturned claspers of males that resemble a 's stinger. The species is found in North America. Like other members of the Panorpa, it likely inhabits moist woodland environments where it scavenges on dead or dying soft-bodied insects.

Habitat
Moist woodland , including dense forests and wet bottomland forests. Based on observations of such as Panorpa helena, the likely frequents areas with abundant leaf litter and damp soil conditions.
Distribution
North America. Specific range details beyond continental distribution are not documented in available sources.
Diet
Scavenging on dead or dying soft-bodied insects. This inference is drawn from documented feeding of related Panorpa , including Panorpa acuta observed scavenging prey in spider webs and Panorpa nuptialis documented feeding on cadaver fluids.
Life Cycle
Complete with four larval instars. Larvae live in soil and leaf litter, scavenging on dead or dying soft-bodied insects. occurs in an earthen chamber in the soil. This pattern is consistent across the Panorpa as documented for related .
Behavior
are known to flit nervously through dense foliage when approached, a observed in such as Panorpa helena. Males use their enlarged genital claspers in courtship and mating. Adults have been observed scavenging in spider webs, stealing prey from the webs of sheetweb-weaver spiders ( Linyphiidae).
Ecological Role
Scavenger and nutrient cycler in forest . Contributes to decomposition of soft-bodied arthropods. May serve as prey for spiders and other . Has documented forensic significance as an early-arriving on human cadavers.
Human Relevance
: Panorpa nuptialis, a , was documented as the first insect to feed on a freshly placed human cadaver in a 2012 forensic study, feeding on fluids from autopsy incisions. This suggests potential value for postmortem interval estimation. No agricultural or medical significance is documented.
Similar Taxa

Taxonomic note
The was described by Webb in 1974. It is recognized as a valid species in the Catalogue of Life and GBIF, with no synonyms recorded.
Data limitations
Published biological information specific to P. setifera is sparse. Most behavioral and ecological details are inferred from well-documented , particularly Panorpa helena, Panorpa nuptialis, and Panorpa acuta. Direct study of this is needed to confirm these traits.
