Panorpa latipennis Hine, 1901
Diagnosis: This is one of four species in the claripennis species group that have short, broad hypovalves; unbranched, straight ventral parameres with broad, thick spines along the mesal margin; and a small, unmodified aedeagal hamulus. All species, except Panorpa claripennis, have some sort of lobe along the mesal surface of the dististyles. Panorpa latipennis males can be distinguished by a small, thumb-like lobe at the ventro-lateral margin of the dististylar, cup-like, basal lobe.
Distribution – Geographical: The distribution of this species appears centered in New England, and can be found as far south as North Carolina along the east coast and west as far as Wisconsin.
Distribution – Temporal: May to July.
Ecology: This species can be found on flowering plants and herbaceous vegetation in moist, hardwood forests at about 4000 feet elevation (Byers, 1954)
Biology: Panorpa latipennis larvae have been described by Boese (1973) from immature reared by G.W. Byers at Giles County, Virginia.
Notes: The small, thumb-like lobe near the base of the male dististyle is unique to this species and makes them readily identifiable.
