Neacreotrichus

Neacreotrichus species are distinguished from other bee fly genera by their small size. They belong to the subfamily Phthiriinae, tribe Phthiriini. Specific diagnostic characters for genus-level identification require examination of wing venation, antennae structure, and other morphological features typical of the tribe.

Species in this genus have been observed in arid and semi-arid environments, including the Sonoran Desert. The type locality and documented occurrences suggest association with desert scrub and adjacent habitats in the southwestern United States and Mexico.

United States (southwestern states) and Mexico.

Adults have been observed in spring, with records from April in the Sonoran Desert region. Detailed seasonal patterns across all species remain undocumented.

As bee flies, adults likely function as pollinators. Larval stages of related genera in Phthiriinae are parasitoids of other insects, though specific hosts for Neacreotrichus remain unconfirmed.

• Other Phthiriinae generaShares subfamily characteristics including reduced wing venation and small body size; distinguished by genus-specific morphological features.
• DiadasiaBoth occur in similar desert habitats and may be found visiting similar flowers; Diadasia is a genus of bees (Hymenoptera) rather than flies, with two pairs of wings and different body structure.
