Very Odd Whatsit - Lutzomyia

Very Odd Whatsit - Lutzomyia
Montrose, Laurens County, Georgia, USA
May 11, 2012
Size: approx. 3mm overall
Found on back porch after dark. I realize this is hardly good enough for a positive ID of any kind, but the bloody thing is driving me nuts. If someone could just please, PLEASE point me in some kind of direction in case I should ever run into this insect again.....

Phlebotominae. formerly Lutz
Phlebotominae. formerly Lutzomyia (classification has been significantly altered in the past 20 years). This is a female, so it's a blood-feeder. For most phlebotomines, it's impossible to ID to species without slide mounting or sequencing their DNA.
As pointed out in another comment, Psathyromyia shannoni (= L. shannoni) is commonly recorded in the southeast USA... This one looks most like P. shannoni as far as the body shape is concerned, but there is no way to be sure based on the photo alone.
If you'd like any of the literature for this group, please contact me directly and I will send it to you.

Moved from Flies.

Compare Lutzomyia (not yet in the Guide, but on the internet). I need to do some reading.

Very cool
our first sand fly in the guide?

Very odd
The long coxae (bases of legs), lack of tibial spurs, and five normal sized tarsomeres are consistent with the Cecidomyiidae (exclusive of the true gall midges), but the wing veins might be wrong. Do you have any more pictures from other angles?

Maybe one of the narrow-winged Psychodidae instead.

Sorry, but this was
the single moment I could capture with this guy. I haven't seen it again, but I am prepared for it, now. If your suspicions pan out, would this species be considered warm-weather-only?

Probably warm weather
I suspect these are like most flies, being found most often in late spring and less often from spring through fall.

The most common species of the Southeast is L. shannoni. I won't attempt a species ID from the photo.

That's fine, John...
at least now I have a direction to go if I should run into it again. As well, I am more prepared for its idiosyncratic behaviour towards being photographed....strange bird, indeed...Thanks!
