When a home is a breeding ground for a bee population, their being there will eventually be felt by all. As the bees swarm around the hive, working so diligently, a person cannot help but notice their presence. Bald Faced Hornets protect their nest (home) very diligently, and have been known to sting more than once (repeatedly) if their home is in danger.
Yellow Jackets are hunters and have been known to eat many times their weight in other insects, flies, caterpillars, etc…
Yellow Jackets, Paper Wasps, and Bald Faced Hornets are types of social wasps that live in colonies.
Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of thirteen segments in males and twelve in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings that make flight difficult or impossible, but none are wingless.
The smallest bee is the dwarf bee (Trigona minima) and it is about 2.1 mm (5/64") long. The largest bee in the world is Megachile pluto, which can grow to a size of 39 mm (1.5"). The most common type of bee in the Northern Hemisphere are the many species of Halictidae, or sweat bees, though they are small and often mistaken for whtms or flies.
The most well-known bee species is the Western honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as beekeeping or apiculture.
