Onichodon
Onichodon is a genus of beetles in the family Eucnemidae (false click beetles), established by Newman in 1838. The genus belongs to the subfamily Macraulacinae and tribe Macraulacini. Mature larvae of at least three Nearctic species have been described, though detailed biological information remains limited. Adults are poorly documented compared to the larval stage.
Physorhinus fusculus
Physorhinus fusculus is a species of click beetle in the family Elateridae. The larvae and pupae have been formally described, and the male genitalia have been redescribed. Mexican agave has been documented as a host plant.
Protoboarmia
porcelain gray (for P. porcelaria), dash-lined looper (for P. porcelaria)
Protoboarmia is a genus of geometrid moths in the subfamily Ennominae, containing at least two described species: P. porcelaria (porcelain gray, dash-lined looper) and P. simpliciaria. Larval stages have been documented from forest habitats, with eggs laid singly on conifer needles. The genus was established by McDunnough in 1920. Taxonomic status varies by source: Catalogue of Life and GBIF recognize Protoboarmia as valid, while some sources consider it synonymous with Alcis.
Thoracochaeta seticosta
Thoracochaeta seticosta is a species of small dung fly in the family Sphaeroceridae, originally described as Leptocera seticosta by Spuler in 1925. It belongs to the subgenus Thoracochaeta, a group associated with marine supralittoral habitats. The larvae have been formally described, distinguishing it from many related species where immature stages remain unknown. The species occurs in Europe and has been recorded in the Nearctic region.
