Description:
There are many kinds of parasitic wasps ranging in size from 1/100 of an inch to 3/4 of an inch. Most resemble wasps except they have no stinger. Many parasitic wasps lay their eggs inside of their host. The eggs then hatch, the larvae grow inside of the host and then chew their way out as adults.
