Wasps are slender with a relatively thin waist and four wings. They’re smooth and somewhat shiny with brightly colored “skin,” generally having sharply contrasting black and yellow patterns. Females can sting multiple times. The males have wings but no stingers. Wasps are predators and feed on insects and spiders.

One type, the umbrella or paper wasp, is colored in dull shades of brown and yellow. It’s usually only a threat when disturbed in its umbrella-shaped nest. Because its stinger is not barbed, it can be removed and reinserted repeatedly, each time metering out enough venom to cause considerable pain.
