Honey Bee Swarming (Left) is the natural means of reproduction in honey bee colonies. Swarming usually occurs in late spring and early summer and begins in the warmer hours of the day. Honey bee swarms may contain several hundred to several thousand worker bees, a few drones and one queen. Swarming bees fly around briefly and then cluster on a tree limb, shrub or other object. Clusters usually remain stationary for an hour to a few days, depending on weather and the time needed to find a new nest site by scouting bees. When a suitable location for the new colony, such as a hollow tree, is found the cluster breaks up and flies to it. Honey bee swarms are not highly dangerous under most circumstances.
Bald-face hornet nest (Right). It is best known for its large, football-shaped paper nest. At the end of summer, or in early Fall, the queen lays eggs which will become females and males. These insects mate, and then all of the nest’s hornets die (including the old queen), except the females who have mated. Mated females overwinter and start their own nests next Spring. They often burrow into an old tree stump to survive the cold. Old nests are abandoned. You can see old nests in Winter, hanging in trees when the leaves have fallen.
