Social Wasps

Family: Vespidae, e.g. Vespula vulgaris

Appearance

Social Wasp
  • Social wasps have yellow and black abdomens. Markings will differ according to species. They have two sets of wings (the hind wings being smaller than the fore wings).
  • Their eyes are kidney shaped and their bodies are more pointed than bees, with a noticeable waist.
  • Social wasps tend to be less hairy than bees.
  • These wasps have long distinctive stingers.

Lifecycle

  • Young Queens overwinter and emerge in the spring to start wasp nest building and lay eggs.
  • Workers (sterile females) emerge during early summer and take over wasp nest building. The queen then continues to lay eggs
  • New queens and males mate in early autumn.
  • The Social Wasps’ nest dies during winter, including all the males and workers. Only Queens survive to the next year.

Habits

  • Colony size: medium to large (up to as many as 25,000 individuals).
  • Preferred wasp nest sites: lofts, wall cavities, old rodent burrows, hollow trees and bushes.
  • Nest construction: pulped wood (paper). Combs are set horizontally. A new wasp nest is produced each year.
  • Swarming: Social wasps do not swarm.
  • Food preferences: Social wasps will consume insects and sweet foods.
  • Social wasp stings readily and repeatedly.
