What is the difference between a bee and a wasp?

Bees and wasps differ greatly in appearance. In general, bees are more full-bodied, hairy and appear to be fuzzy, a characteristic that helps them collect and disseminate pollen. Wasps are more slim-bodied, have slender legs and their body appears non-hairy and shiny. Additionally, unlike bees, which can sting only once—the process is ultimately fatal to them—wasps can sting multiple times and buzz merrily away.
