The Difference Between Wasps and Bees
There are over 30,000 identified species of wasps, the most common being Yellowjackets, Baldfaced Hornets, and Paper Wasps. The body is slender with a narrow waist and cylindrical legs. The skin appears smooth and shiny. Their sting can be nasty, but wasps are extremely beneficial to humans, preying on other pest insects―such as caterpillars, flies, and crickets―either for food or as host for their larvae.
Bees, on the other hand, have fuller bodies and are hairier than wasps, and have flat hind legs which are used to collect and transport pollen. 80% of the pollination required by most fruits, legumes, and vegetable seed plants and ornamentals is handled by honey bees.
