Neacreotrichus diversus

Accurate identification of Neacreotrichus diversus requires examination of genitalic structures and other microscopic characters. The genus Neacreotrichus is distinguished from related genera in Phthiriinae by subtle morphological characters of the head and wing venation. Distinguishing N. diversus from other species in the genus requires specialist knowledge and reference to original description and type specimens. No field identification guides are known to cover this species specifically.

Has been observed in the Sonoran Desert region, specifically in Tucson Mountain Park, Arizona. The habitat is characterized by desert vegetation including blooming cacti and wildflowers. Specific microhabitat preferences are not documented.

United States: recorded from Arizona. The species' full range is poorly documented due to limited collection and observation records.

One record from April 2010 in Arizona. Seasonal activity pattern is otherwise undocumented.

Adults have been observed visiting flowers. Specific behavioral observations are limited to a single field record.

As a member of Bombyliidae, likely functions as a pollinator of flowering plants in its habitat. The subfamily Phthiriinae includes species with diverse larval habits, but specific ecological role of N. diversus is undocumented.

No documented economic or medical importance. Occasionally encountered by naturalists and entomologists in the Sonoran Desert region.

• Other Neacreotrichus speciesCongeneric species share small size and general Phthiriinae morphology; require microscopic examination for separation.
• Other Phthiriinae generaSmall bee flies in the same subfamily share general appearance; genus-level identification requires examination of head capsule and wing characters.
