Agrilus obsoletoguttatus
Beech Borer
Agrilus obsoletoguttatus is a small metallic wood-boring beetle in the family Buprestidae, native to North America. It is among the smallest jewel beetle species utilized as prey by the specialist predatory wasp Cerceris fumipennis, which provisions its underground nests with paralyzed buprestid beetles. The species has been documented in nest caches containing up to 13 individuals, reflecting its small size relative to larger buprestid prey.

Ammophila
Thread-waisted Sand Wasps
Ammophila is a large, cosmopolitan genus of solitary hunting wasps in the family Sphecidae, comprising over 200 species distributed across warmer regions of all continents except Antarctica. These thread-waisted wasps are characterized by their elongated, slender petiole connecting the thorax and abdomen, and their distinctive nesting behavior involving burrow excavation and caterpillar provisioning. Females construct underground nests in sandy or compact soils, paralyze caterpillars with their sting, and provide this food source for their developing larvae. The genus serves as a host for Strepsiptera endoparasites and is subject to nest parasitism by satellite flies and other organisms.

Bembecinus
sand wasp, sand wasps
Bembecinus is a cosmopolitan genus of sand wasps in the family Crabronidae, with approximately 200 described species worldwide. These small to medium-sized wasps are known for their distinctive eye morphology—strongly convergent at the bottom of the face and strongly divergent at the top of the head—and for practicing progressive provisioning of their larvae. Females construct burrows in sandy substrates and hunt leafhoppers to feed their offspring, while males exhibit complex alternative mating tactics including digging for pre-emergent females and patrolling for mates.

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.

Bicyrtes
Bicyrtes is a genus of large, often brightly colored predatory sand wasps in the family Crabronidae. The genus name derives from the two noticeable projections arising from the rear of the mesosoma. Most species nest in sandy or coarse soils and provision their burrows with paralyzed true bugs, primarily Pentatomidae (stink bugs), though some species utilize Reduviidae (assassin bugs) and Coreidae (leaf-footed bugs) as prey. The genus contains approximately 11 described species distributed across North America, with some species extending into Central and South America and the Caribbean, including the Galápagos Islands.

Clitemnestra
Clitemnestra is a genus of small sand wasps in the family Crabronidae, containing at least 60 described species. Members of this genus are predatory wasps that hunt various sap-feeding insects, particularly planthoppers, leafhoppers, and related Hemiptera. The genus was revised by Bohart in 2000, which included the merger of the former genus Ochleroptera into Clitemnestra. These wasps are generally inconspicuous due to their small size, with some species measuring only 5–6 millimeters in body length.
