Chrysops cincticornis
Ring-clawed Deer Fly
Chrysops cincticornis is a deer fly in the family Tabanidae, first described by Walker in 1848. It is commonly known as the Ring-clawed Deer Fly. The species has been documented in Vermont and other parts of the United States, with 291 observations recorded on iNaturalist. Research on this species has focused on its oviposition behavior and fecundity, with laboratory studies showing females deposit eggs in gelatinous masses on mud substrates near water, averaging 156 eggs per female.

Cramptonomyia spenceri
Cramptonomyia spenceri is a species of fungus gnat in the family Pachyneuridae, first described by Charles Paul Alexander in 1931. It belongs to a small family of primitive nematoceran flies. The species is distinct from the mosquito Aedes spencerii, with which it shares a specific epithet but differs in family, genus, and ecological role. Available sources provide taxonomic placement but lack detailed biological information.

Exiliscelis
Exiliscelis is a genus of flies in the family Canthyloscelidae, established by Hutson in 1977. It contains a single described species, Exiliscelis californiensis. Members of this family are small, obscure flies often associated with moist or wetland habitats. The genus is part of the subfamily Synneurinae, a group of primitive nematoceran flies with limited ecological documentation.

Protaxymyja thuja
Protaxymyia thuja is a species of fly in the family Axymyiidae, a small and poorly known family of primitive nematoceran Diptera. The species was described in 2014 by Fitzgerald and Wood. Axymyiid flies are typically associated with decaying wood in forested habitats, though specific details for this species remain limited. The family is considered one of the most basal lineages within the true flies.
