Order Hymenoptera encompasses Ants, Bees, and Wasps. About 18,000 types reside in North Amerca (excluding Mexico). Like other insects, they have chewing mouth parts for breaking down food sources. Ants can deliver bites through their mandibles while Bees and Wasps sting to repel threats and subdue prey. The order typically operates during the warm summer months across Tennessee. Bees are an utterly important part of the state's ecosystem, eating pollen and nectar to help raise their young - Bee by-products are essential in many human products and their pollinating action serves many other purposes. While Bees and Wasps live in carefully constructed nests, the social Ant survives in colony made up of networked tunnels. The furry Bumble Bee is not aggressive by nature though disturbing an in-ground nest of Yellow Jacket wasps will be a mistake made only once!
