European Paper Wasp

Fascinating facts about the European Paper Wasp

• European paper wasps eat a buffet of insects, not just caterpillars. One study in Europe found that the prey items brought back to nests represented three insect orders, and other Eastern European work listed five orders, Lepidoptera, Hymenoptera, Coleoptera, Orthoptera, Hemiptera, plus adult flies. This broader menu lets colonies thrive when any single food source runs low, giving them a survival edge over native wasps that rely mainly on caterpillars.
• A single European paper wasp queen can out-produce native rivals by a factor of four to five. In Michigan field tests, single-foundress colonies of P. dominula were four to five times as productive as the colony cycle of P. fuscatus, and across North America they beat Polistes metricus colonies in the same way. Higher output means faster colony expansion and more workers to defend nests, helping the species dominate new habitats.
• European paper wasp larvae grow up six days faster than those of the native P. fuscatus, even when eggs hatch on the same day. This six-day lead shortens the vulnerable period before workers appear, letting colonies start foraging and defending sooner. Faster development reduces the window for parasites and predators, sharpening the species' competitive edge.
• Introduced populations of P. dominula carry high genetic diversity, and in some North American sites more than 80 wasps have been seen banding together to reuse an old nest. Such aggregations likely boost colonisation speed, because many founders share the workload and increase the chance that at least some survive in unfamiliar terrain.
• The European paper wasp entered North America in the late 1970s, first recorded in Massachusetts, and by 1995 it was spread throughout the northeastern United States. Within two decades it pushed west to Colorado, with confirmed sightings as early as 2013. This rapid jump shows how human transport and the wasp's flexible nesting habits let it leap across continents.
