Dasylechia atrox
(Williston, 1883)
Dasylechia atrox is a of robber fly ( Asilidae) in the Laphriinae. Once considered ultra-rare, its true geographic range is now being defined primarily through photographic observations on iNaturalist, which have substantially outnumbered collected specimens. The species belongs to a small of distinctive, large-bodied robber flies.

Identification
Dasylechia atrox is a large, robust robber fly. Members of the Dasylechia are characterized by their substantial size among Asilidae and distinctive . Specific diagnostic features for D. atrox versus require examination of detailed morphological characters not readily apparent from photographic records alone.
Distribution
The documented range of Dasylechia atrox has expanded significantly through citizen science observations, with iNaturalist records now defining its true distribution more comprehensively than traditional museum specimens. Historical collection records were sparse, contributing to its former status as ultra-rare.
Similar Taxa
- Other Dasylechia species share the large body size and general Laphriinae ; precise identification requires detailed examination of genitalia and other subtle characters

Documentation shift
The exemplifies a significant shift in how rare insect distributions are documented. Photographic observations through platforms like iNaturalist now substantially outnumber physical specimens in collections, challenging traditional paradigms about the necessity of specimen collection for understanding species ranges. However, photographic records alone cannot provide genetic data, detailed anatomical examination, or voucher specimens for definitive taxonomic work.
