When most people think of wasps, they imagine a stereotypically striped stinging insect. Such wasps are part of the family Vespidae, but they are, in fact, a minority of species and unrepresentative of their order. Taken by sheer number of species, the average wasp is quite a different animal: timid, stingless, and very, very small.

Encarsia pergandiella is scarcely larger than a speck of dust. This particular speck, however, is our friend. Encarsia is used extensively in agriculture as a natural control of the silverleaf whitefly, a pest of tomatoes, cotton, cucumbers, and other crops. Like the majority of wasps, Encarsia is not aggressive and does not sting.
