Tachinid Fly, we believe

Hi Dave,
We needed to do a web search to determine that your location is in the Canary Islands off the west coast of Africa.  We are relatively certain your fly is a Tachinid Fly, a member of a large family with members that parasitize insects and other arthropods.  Different species of Tachinid Flies are often very host specific, concentrating on a single species or genus as their host.  The female Tachinid Fly lays eggs on or inside the host and the larval flies develop as internal parasites, eventually killing the host.  Tachinid Flies are important biological control agents.
