Bembecinus floridanus
sand wasp
Bembecinus floridanus is a small sand wasp in the family Crabronidae, first described by Krombein & Willink in 1951. As a member of the genus Bembecinus, it exhibits the characteristic traits of this group: strongly convergent eyes at the bottom of the face and strongly divergent at the top of the head, along with a petiolate or nearly petiolate second submarginal cell in the forewing. The species is found in North America and, like other Bembecinus, is a solitary ground-nesting wasp that provisions its larvae with prey.
Bembecinus nanus
Bembecinus nanus is a small sand wasp species in the tribe Stizina, family Crabronidae. Like other members of its genus, it excavates burrows in sandy substrates and provisions nests with leafhoppers (Cicadellidae) for its larvae. The species practices progressive provisioning, bringing prey to the developing larva on an as-needed basis rather than mass provisioning. It is one of approximately 190 Bembecinus species worldwide and among ten species recorded from North America north of Mexico.
