Reproduction

Sexual. Males and queens produced in late autumn. Fertilised queens overwinter , and then start a new colony in early spring . She produces sterile females, called workers, throughout the season .c. 1000-2000 queens produced per colony in autumn. Average colony density in New Zealand beech forest c. 12 per ha.

Annual colonies initiated in spring by one queen. Colony expands through season and then produces sexual stages in autumn, before colony breaks down . In each cell of a new nest , the queen lays a single egg , which hatches into a larvae in 5 to 8 days. After five moults over about 90 days (the length of time spent in each stage is determined by environmental conditions ), each larva spins a silken cap over the cell and pupates. After about 80 days an adult worker wasp emerges .
