Identification
As a member of Orchesella, this likely exhibits the -characteristic elongate body form and well-developed furca (springing organ). Positive identification to species level requires examination of chaetotaxy (bristle arrangement) and other microscopic features, as Orchesella species are morphologically similar and often distinguished by subtle differences in setation patterns and body proportions. The specific status of O. texensis was established based on diagnostic morphological characters separating it from .
Distribution
Southern North America, with records indicating presence in the south-central United States.

Taxonomic Note
placement has varied in literature: Wikipedia lists Entomobryidae, while GBIF, Catalogue of Life, and iNaturalist recognize Orchesellidae. Modern classifications treat Orchesellidae as a valid family within Entomobryoidea, separate from Entomobryidae.
Class Assignment
iNaturalist lists Class as , while other sources use Collembola. Collembola is now widely treated as a class-level within Pancrustacea, with Entognatha being a broader grouping of mouthpart-concealed hexapods.
