I could only make a few bad flash photos. I use f16 indoors with flash which works nicely but f11 with flash is required outdoors. I didn't have time to change settings. I can see 8 scutellar bristles, so this should be Ornithomya avicularia, correct? I have a specimen but i will wait to examine it. Thank you for your time. johnes81 attached the following image: [153.61Kb] John and Nini. Naturalists not experts.

I see the claws and the pulvilli but what is the feather-like object called? does this piece even have a name? I suppose the purpose of it is for clinging to a host? or perhaps a sex comb? vide attachment with red arrow. johnes81 attached the following image: [52.24Kb] John and Nini. Naturalists not experts.
