Anoplius
Blue-black Spider Wasps
Anoplius is a large genus of spider wasps in the family Pompilidae, commonly known as the blue-black spider wasps. The genus contains over 200 described species distributed across multiple subgenera, with approximately 26 species occurring in Colorado alone. Most species are characterized by predominantly black or blue-black coloration, making field identification challenging without close examination. Members of this genus are solitary hunters that prey primarily on spiders, with most species specializing on wolf spiders (Lycosidae) and some exhibiting broader prey preferences.
Aporus luxus assimilis
Aporus luxus assimilis is a subspecies of spider wasp in the family Pompilidae, originally described by Banks in 1917. Current taxonomic databases list this name as a synonym of Aporus luxus rather than a valid subspecies. The parent species A. luxus is a small iridescent blue-black wasp, 8–15 mm in length, known from western North America. Adults are commonly found on flowers of umbellifers and other plants where they feed on nectar. Females hunt trapdoor spiders (family Euctenizidae), paralyzing them and using the spider's own burrow as a nest for their offspring.
