Pachypsylla celtidisumbilicus
Hackberry Disc Gall Psyllid
Pachypsylla celtidisumbilicus is a species of hackberry psyllid that produces distinctive disc-shaped galls on hackberry leaves (Celtis spp.). Adults emerge in fall and seek shelter to overwinter, often becoming household nuisances when they congregate on building exteriors. The species is one of at least seven Pachypsylla species associated with hackberry in North America, each producing a characteristic gall morphology.

Helena's Scorpionfly, common scorpionfly
Panorpa helena is a species of scorpionfly in the family Panorpidae, described by George Byers in 1962. It is one of the most common and widespread scorpionfly species in eastern North America. The species is distinguished by three complete dark bands across its yellow wings and, in males, the presence of an anal horn on the sixth abdominal tergum. Adults are typically encountered in dense, moist forest habitats where they flit nervously through foliage.
Rhagio plumbeus
Lead-colored Snipe Fly
Rhagio plumbeus is a snipe fly in the family Rhagionidae, characterized by its lead-gray coloration that gives the species its name. Adults are medium-sized flies found in moist woodland habitats during late spring and early summer. Like other members of the genus Rhagio, this species exhibits sexual dimorphism in eye structure, with males having holoptic eyes and females having dichoptic eyes. The species is widely distributed across eastern and central North America.
