This fly seemed to be interested in laying eggs in the bud of a cactus flower (I think the cactus was Pilocereus sp.) It maneuvered around the bud for more than fifteen minutes and seemed to be trying to oviposit into it. Thanks in advance for any ideas about what it might be. A couple additional photos to follow.

Nice photos But it would probably help the experts if you say where in the world the photo was taken

Sorry, I forgot to give the location. It is St. Martin in the Lesser Antilles.

hello Definitely female Lonchaeidae, all black legs and a very long antennal segment would point to the genus Silba or Neosilba - and as only Neosilba occurrs in the Neotropics thats what it is. Difficult to get to species level from a photograph as there are a few very similar species in this area - See link below for maps and further info ..........

Thanks Paul and Ian! As a side note, I was eating a fruit from the same species of cactus today and it contained larvae. I didn't have my macro lens with me, but perhaps it was the same species. __________________ http://www.lesfruitsdemer.org |
