Sphecidae (Nest-building solitary wasps)
The family Sphecidae consists of many species of solitary nesting wasps. Some, such as Isodontia and Trypoxylon, have received their own page in the species guide. This page is a general description of the family and encompasses all sphecids from our project that were not identified to genus or species.
Sphecid wasps are frequently all dark, with few markings and almost no hair on their bodies. They do not fold their wings at rest. Sphecids often have a square shaped head when seen face-on, have low set antennae and a silvery “mustache” of hairs or yellow markings on their face. Many are quite small. Most of the sphecids in Bee Atlas blocks are small aphid wasps.
Sphecids are solitary nesting wasps and stock their nests with paralyzed prey. Many sphecids store aphids in their nests as the food source for their young. They may collect hundreds of aphids per nests. Most sphecids in Bee Atlas blocks use light-colored resin to seal their nests, and may stick debris to the plug surface. Resin plugs with a lot of debris can be confused with mud with a lot of debris.
Sphecid wasps are common in the Bee Atlas blocks. They primarily use holes in the 3rd column (the smallest holes) though we do get nests from the upper second column holes.
