Summary

Myrmeleon is a genus of antlions with several species found primarily in North America. Their larvae create distinctive funnel-shaped pits in sandy substrates to trap prey, usually ants. The adults exhibit noticeable physical characteristics that aid in identification, contributing to their identification in the study of entomology.

Physical Characteristics

Myrmeleon adults are typically recognizable by their stockier build, white pterostigmas, and often simpler body markings.

Identification Tips

Look for their characteristic funnel-shaped pits dug in loose sand, which are unique to their larvae. Adult identification can be aided by stocky body structure and color patterns.

Habitat

Larvae inhabit sandy areas where they can dig pits; adults may be found in similar environments.

Distribution

12 species in the region (primarily in the eastern and southwestern United States) and about 189 species worldwide.

Diet

Larvae feed primarily on ants and other small insects trapped in their pits.

Life Cycle

Larvae create funnel-shaped pits to trap prey. They are capable of moving backwards out of their pits to avoid predation; life cycle details may vary by species.

Reproduction

Not specifically detailed; however, like many insects, reproduction likely involves egg-laying in suitable habitats.

Predators

Larvae can fall prey to dune crickets, such as Schizodactylus inexspectatus.

Ecosystem Role

Myrmeleon species play a role in controlling ant populations and serve as prey for higher trophic levels.
