Despite being important pollinators, solitary ground-nesting bees are inadequately represented by pesticide risk assessments reliant almost exclusively on honeybee ecotoxicology. Here we evaluate the effects of realistic exposure via squash crops treated with systemic insecticides (Admire-imidacloprid soil ...
Insect pollinators are threatened by multiple environmental stressors, including pesticide exposure. Despite being important pollinators, solitary ground-nesting bees are inadequately represented by pesticide risk assessments reliant almost exclusively o
We're talking about solitary wasps and bees that are not part of a colony, but nest individually (not the social ground-nesting wasps and bees such as yellowjackets and bumble bees). The important things to remember about solitary ground-nesting wasps and bees are: (1) they nest ...
Studies of these bees often point to guarding and resource limitation as factors leading to social nesting. The large carpenter bee Xylocopa virginica L. (Hymenoptera: Apidae) is one species that exhibits both solitary and social nesting behaviour within the same populations. This paper first ...

Halictid bees construct larval cells under- ground. Each cell contains a pollen ball on which the female lays a single egg. Many species are bivoltine in a year and multiple-female nests occur only after the second reproductive period16,35. By carefully excavating the nests at the end of a...

Cicada-killer wasps are ground nesting. They are solitary (meaning femalesprovisiontheir own offspring with food), but frequently nest in aggregations. Like most other non-social, cicada-killers areparasitoids, and the larvae feed on the bodies of otherarthropods. Adult females hunt forcicadas, usu...
