I have yet to post my final post for the year on the monarch Butterfly but I can guarantee that all, or at least most, of you will be delighted by the beauty of the butterfly. Most of you may not, however, share the same view of this 13mm long fly. Apart from the fact that it is from the order of Diptera (true flies are insects of the order Diptera - from the Greek di = two, and ptera = wings) I can tell you nothing about her. I'm assuming (big leap here) that it's a she because I assume that the two little 'tails' are in fact oviposter. I may be wrong. Presumably someone with more knowledge will correct me if I am. The Diptera include files, mosquitos, gnats, midges, and no-see-ums. There are about 120000 known species of true flies alive today.
