Any ideas for an identification are very welcome - but not expected!  I just found this in my latest batch of flies from French Guiana, courtesy of Jean Cerda, and had to post here to show everyone ... isn't it amazing?!  The green colour isn't the same as you would expect to see on Lucilia sp. or Gymnocheta viridis - this metallic green is actually dusting

This is a Chrysoexorista sp. - the colours are very transient and are lost after the specimen has dried out, leaving a greasy, brown dusting. The colours are not lost through grease though and Monty Wood things it is due to the loss of fluid from the scales that create the structural colours

Hi Chris, That's an amazing specimen. I have one collected in FG too (montagne des chevaux). It looks like very similar to your specimen excepted the presence of three longitudinal dark stripes on thorax. I have first pinned it but after reading your post, I have put it again in alcohol. I wouldn't like that he loss his beautifull green colors. Did you know a process to help it to keep its green colors? Cheers |

I have an African species with similar but less extensive dusting. If Monty is right, I wonder if "relaxing" the specimen might restore the colours to a degree (something which works sometimes for the eye patterns of tabanids). Steve |

Here is my green-scaled tachinid freshly taken in Zambia, which looks very similar to http://www.dipter...d_id=24923 Steve sd attached the following image:  [128.45Kb] |

Wow, that does look very similar to the one you linked to - in pretty much every detail ... nice fly!

Blepharella is close to Sturmia ( notice the short T5 and comb on hind tibia). As such it is sometimes placed in the tribe Sturmiini and sometimes in the tribe Goniini --to which Chrysoexorista belongs... Does anyone have examples from other genera? Steve Edited by sd on 29-10-2011 13:34 |
