Comments

There are 14 species in the genus Archytas in North America.  In the larval stage Tachinids are parasitoids of other insects, but the most common hosts are caterpillars.  Most adult females deposit eggs directly on the body of the host.  Upon hatching, the larva burrows into the host and feeds internally.  When fully grown it leaves the host and pupates.
