The subfamily Crabroninae is the most diverse group in the wasp family Crabronidae, containing over 100 genera. The subfamily consists of solitary, predatory wasps. The adult females of many groups dig tunnels in the ground for nesting, but others use different techniques, including the construction of tube-like mud nests (e.g., Trypoxylon politum).
