Delta
potter wasps
Delta is a genus of Old World potter wasps in the family Vespidae, subfamily Eumeninae. The genus was established by Henri Louis Frédéric de Saussure in 1855. Species are predominantly distributed through tropical Africa and Asia, with some representation in the Palearctic region. A few species have been introduced to the Nearctic and Neotropical regions. Delta wasps construct characteristic pot-shaped mud nests and provision them with paralyzed caterpillars for their developing larvae.
