REDUCED NZ-Ento-Soc-Insect-Playing-Cards_RhopalumCommon name: Sphecoid wasp

Order: Hymenoptera  Family: Sphecidae

Size: 7- 14 mm long

These wasps hunt for flies on sunny day, sometimes catching prey as they visit flowers. The wasps will sting their prey to immobilise them and then carry them back to their nests for their larvae. These wasps nest in twigs and holes dug into trees by beetles and each nest is usually made up of between 7-11 cells. The females place their immobilised prey into these cells, lay eggs on them and then close the cells up with frass.
