Caliadurgus fasciatellus
Blotchwing Spider Wasp
Caliadurgus fasciatellus is a small spider wasp in the family Pompilidae, subfamily Pepsinae. It ranges from Western Europe to the Far East of Asia. The species hunts orb-weaving spiders, paralyzes them, and provisions underground burrows for its larval offspring. It was historically confused with Priocnemis hyalinata due to taxonomic errors regarding type species designations.
Cerceris verticalis
Cerceris verticalis is a solitary predatory wasp in the family Crabronidae. Like other members of the genus Cerceris, it constructs underground nests and provisions them with paralyzed insect prey for its larvae. The species was described by Frederick Smith in 1856 and occurs in North America and Middle America. As a member of the diverse genus Cerceris, it likely specializes on a particular prey group, though specific prey associations remain undocumented in the available sources.
Entypus unifasciatus
spider wasp
Entypus unifasciatus is a spider wasp species in the family Pompilidae. Females hunt large spiders, paralyze them with venom, and provision underground burrows as food for their developing larvae. The species exhibits a broad transcontinental distribution across the Americas. Adults display distinctive coloration with black bodies, bluish sheen, yellow antennae, and variable orange-banded wings.
Euodynerus annulatus imperialis
Euodynerus annulatus imperialis is a subspecies of mason wasp in the subfamily Eumeninae. As a subspecies of the widespread E. annulatus, it shares the species' distinctive burrow-nesting behavior, including construction of curved mud chimneys aboveground. The subspecies exhibits color and marking variations characteristic of the three western subspecies of E. annulatus. Females provision nests with paralyzed caterpillars from moth families Crambidae, Pyralidae, and Noctuidae.
Pterocheilus sinopis
Pterocheilus sinopis is a species of solitary mason wasp in the family Vespidae, subfamily Eumeninae. It is one of approximately 40 species in the genus Pterocheilus, a group characterized by fossorial (burrow-digging) nesting behavior. The species was described by Richard M. Bohart in 1999. Like other members of its genus, females are equipped with specialized anatomical adaptations for excavating soil burrows, including a psammophore (a "beard" of setae on the palps) for transporting soil away from nest sites.
