Description

Tachinid flies are large, dark, and bristly, resembling bees, wasps, or houseflies.

Life cycle

Some species lay their eggs on foliage, where a nearby host insect will feed on them. Others glue their eggs to the outside-or insert them inside-the host’s body. The emerging larvae parasitize and kill the hosts. Tachinid flies complete one or a few generations each year.

Tachinid flies attack the larvae of butterflies and moths, beetles, sawflies, and several other insect orders.
