Louis - female conopids have a complex abdominal structure where the fifth segment is produced ventrally to form a theca (though this is quite small in Sicus ferrugineus), and the seventh and eighth segments are enlarged as well. These structures form a clasping organ used when ovipositing on bees and wasps. By comparison the male genitalia are insignificant! In the Gallery, Gerard has posted a number of good photos of specimens which show the differences well. Your photos show a female. Perseus - your Shoreham fly has a much shorter second tergite. This could be a male S. ferrugineus, or a male or female S. abdominalis (that would be a great find!). Another possibility is that it could be a Myopa species which can look rather like a stumpy Sicus. On balance I'd plump for a male S. ferrugineus. Tony ---------- Tony Irwin |
