Dasymutilla klugii

As a member of the genus Dasymutilla, D. klugii can be distinguished from other velvet ant genera by features of the genus, though specific diagnostic traits for this species are not detailed in available sources. The species is part of the Müllerian mimicry complex of North American velvet ants, which share aposematic coloration warning of their defensive sting.

Found in south-central North America; specific microhabitat preferences are not documented, but related species in the genus are associated with open, sandy areas where host wasp nests occur.

South-central North America, ranging from Utah to Puebla, Mexico. Most commonly encountered in Texas.

• Sphecius grandis - parasitoidCicada-killer wasp nests are used to incubate young; larvae develop as parasitoids of the host's brood.

As with other Mutillidae, females are believed to deposit eggs in host nests. Larvae develop as ectoparasitoids, consuming the host larva or pupa. Adults emerge from host nests. Specific developmental details for D. klugii are not documented.

Females run rapidly across the ground while searching for host nests, a behavior typical of velvet ants. Both sexes have been observed producing audible squeaking sounds (stridulation) by rubbing abdominal segments together when disturbed.

Acts as a parasitoid of ground-nesting wasps, potentially regulating populations of cicada-killer wasps and possibly other host species.

Females can deliver a painful sting if handled; caution is advised. The species is frequently encountered by observers in Texas, making it one of the more commonly observed velvet ants in its range.

• Dasymutilla occidentalisAnother large, brightly colored Dasymutilla species with aposematic coloration; both are part of the same Müllerian mimicry complex and share the wingless female morphology.
• Dasymutilla gloriosaSame genus with similar biology, though D. gloriosa females exhibit extreme sexual dichromatism with dense white setae resembling plant seeds.
