About Crabro cribrarius (Linnaeus, 1758)
Crabro cribrarius is a species of digger wasp first described by Linnaeus in 1758. Females of this species reach a body length of 11–18 millimetres (0.43–0.71 inches), while males reach 9–17 millimetres (0.35–0.67 inches). Individuals of this wasp species have black and yellow bodies. Males have distinct, conspicuous trowel-shaped dilations, or shield-like structures, on their fore tibiae that are used for excavating burrows. Their antennae are filiform, with expanded central articles. Their tibiae are yellowish-brown and lightly mottled. This species is distributed across most of Europe, and extends east through the Palearctic region to Korea. These digger wasps live in dry sandy areas, lowland heaths, and coastal dunes. They can also be found in urban areas, spruce forest edges, chalk grassland, and open woodlands.
