Summary

Amblypsilopus is a diverse genus of flies within the Dolichopodidae family, characterized by distinct sexual dimorphism in morphology, particularly within various species groups. It encompasses around 350 species, many of which are not well-documented and can be challenging to identify.

Physical Characteristics

Species can be identified by male secondary sexual characters and wing markings. The type species presents a specific wing deformation as a modified secondary sexual characteristic.

Identification Tips

Male secondary sexual characters, wing markings, and detailed morphological features help in identifying species within the genus. Key references include Steyskal's identification keys.

Habitat

Amblypsilopus species are found in various environments across the Nearctic and tropical regions.

Distribution

Primarily distributed in the Nearctic region and pan-tropical areas, with numerous species in North America, particularly north of Mexico.

Diet

Larval stages are typically predacious, feeding on other small invertebrates. Adult feeding habits may include nectarivory.

Life Cycle

Life cycles involve complete metamorphosis with egg, larval, pupal, and adult stages. Specific life cycles may vary by species.

Reproduction

Reproductive strategies involve mating displays primarily by males, with distinctive secondary sexual characteristics aiding in the process.

Ecosystem Role

Amblypsilopus species likely play a role in local ecosystems as predators of other small arthropods and as potential pollinators as adults.
