probable Chrysomya megacephala

Moved from Blow Flies.

Armpit hair
If you're following the keys you have to look underneath. Lucilla has a hairless white flap under the wing root and hairs at a particular spot on the body near the front of the thorax.

"Looks like" does have some value but I won't guess.

 
Lateral View
John,
Thanks to your advice, I added a lateral view showing the flap. I originally wasn't going to subscribe that image, as it is not the quality of this dorsal view. However, it does show important information.

 
I think it may be a Chrysomya
I think it may be a Chrysomya species, perhaps C. rufifacies. This is because of the black first abdominal segment and black rims of the other abdominal segments. I don't know any Lucilia sp. that have these black markings.
