Dasymutilla arenerronea

Bradley, 1916

Dasymutilla arenerronea is a of velvet ant in the Mutillidae, described by Bradley in 1916. Like all mutillids, it is actually a rather than an , with wingless females and winged males. The species belongs to a large of solitary wasps that primarily target ground-nesting bees and wasps. Females are capable of delivering a painful sting, a trait common across the family.

Appearance

Specific morphological details for D. arenerronea are not documented in available sources. As a member of Dasymutilla, females are wingless and densely hairy, giving the characteristic 'velvet' appearance. Males possess wings. Most Dasymutilla exhibit aposematic coloration, typically combinations of red, orange, or white with black.

Habitat

Specific preferences are not documented. Related Dasymutilla occur in arid and semi-arid environments including deserts, prairies, and sandy areas where nests are accessible.

Distribution

Documented from the southwestern United States. The specific epithet 'arenerronea' (from Latin arena = sand, erronea = wandering) suggests association with sandy .

Seasonality

activity periods are not documented for this .

Host Associations

Ground-nesting bees and wasps - Specific unknown; Dasymutilla generally parasitize nests of solitary and bees, especially crabronid and sphecid wasps

Life Cycle

Not documented for this . Related species have solitary : females locate nests, lay in , and larvae consume host pupae or larvae.

Behavior

Not documented for this . Female Dasymutilla are known for rapid, erratic running while searching for nests. Both sexes can produce audible stridulation by rubbing abdominal segments together.

Ecological Role

As a , contributes to regulation of ground-nesting hymenopteran . Females participate in Müllerian mimicry complexes with other aposematic .

Human Relevance

Females can deliver a painful sting if mishandled, though no specific reports exist for this . Not known to be economically significant.

Taxonomic History

The was described by Bradley in 1916. A major 2010 molecular revision by Williams et al. synonymized many Dasymutilla species, but D. arenerronea was not among those lumped into D. bioculata, suggesting it represents a distinct lineage.

Etymology

The specific epithet combines Latin 'arena' (sand) and 'erronea' (wandering/erroneous), possibly alluding to its sandy and perhaps initial taxonomic confusion.
