Calliopsis pugionis
Pugnosed Miner Bee
Calliopsis pugionis is a solitary ground-nesting bee in the family Andrenidae, described by Cockerell in 1925. It is found in North America, where it excavates burrows in sandy soil. The species exhibits sexual dimorphism with females larger than males, and has a female-biased investment sex ratio consistent with local mate competition theory. It serves as the host for the cleptoparasitic bee Holcopasites ruthae.
Colletes kincaidii
Kincaid's Cellophane Bee, Kincaid's Polyester Bee
Colletes kincaidii, known as Kincaid's cellophane bee, is a solitary ground-nesting bee in the family Colletidae. Like other Colletes species, females construct individual burrows and line brood cells with a cellophane-like secretion from the Dufour's gland, creating waterproof chambers for larval development. The species has been documented as a host for the cleptoparasitic bee Epeolus compactus, which exploits its nests. It is found in North America, with confirmed records from Vermont.
Macropis nuda
Dark-footed Yellow Loosestrife Bee
Macropis nuda is a small, ground-nesting solitary bee in the family Melittidae, native to northern North America. It is a highly specialized oligolectic species that forages exclusively for floral oils and pollen from Lysimachia ciliata (Primulaceae). The bee exhibits unique adaptations for oil collection, including dense white scopae on the posterior tibiae that use capillary action to hold oils. It is univoltine, with offspring hibernating as pupae in cocoons until the following spring.
Osmia chalybea
Osmia chalybea is a solitary mason bee (Megachilidae) native to North America. It nests in pre-existing cavities and has been studied as a potential pollinator for orchard crops, particularly blueberries. The species serves as a host for the cleptoparasitic bee Stelis ater. It is one of several Osmia species evaluated for commercial management in agricultural pollination systems.
Pemphredon inornata
aphid wasp
Pemphredon inornata is a small solitary wasp in the family Crabronidae, commonly known as an aphid wasp. The species hunts aphids as prey for its larvae, paralyzing them and transporting them to nest cavities in hollow stems, twig pith, or pre-existing holes in wood. It is one of approximately 20 recognized Pemphredon species in North America north of Mexico. The wasp has been documented exhibiting rapid, evasive flight that allows it to bypass ant guards at aphid colonies.
