Parasitic fly

5970  I reside in the Roodepoort area in Gauteng Province of South Africa and I wondered if you can shed some light on the subject of this kind of fly, it is not one of the more common flies in our area.  It is late Autumn 10 April 2017 so it is not yet cold. It came flying in to the house late evening, it doesn’t fly very fast.  It is 13mm from the tip of the wing to the tip of it head.  Green eyes.  The body is yellowish red-brown in colour. Thank you for the opportunity to find out what kind of fly this is.  Kind regards,  Samantha 

This fly looks like something in the family Tachinidae, but I cannot offer a more specific identification. All flies in this family are parasitic on other arthropods, mainly other insects. Ed Saugstad, retired entomologist; Sinks Grove, WV.
