Grass-carrying Wasps, Grass-carrier Wasps
Isodontia is a genus of solitary wasps in the family Sphecidae, commonly known as grass-carrying wasps. Females construct nests in pre-existing cavities such as hollow stems, window tracks, or abandoned beetle tunnels, lining them with dry grass or hay. They provision nests with paralyzed Orthoptera (tree crickets and katydids) as food for their larvae. Several species are invasive in Europe, with Isodontia mexicana being the most widespread non-native species.
