Green Bottle Fly - Lucilia - female

Green Bottle Fly - Lucilia - Female
Baiting Hollow, Suffolk County, New York, USA
August 5, 2008
I thought this would be an easy one, but after looking at a lot of flies I can't determine where this one should go.

Maybe your photo's too good? LOL.
It certainly looks better than many of the green bottle fly shots we have here. That's what I think you've got, perhaps Lucilia like this one:



Eyes are smaller on yours since it is a female.

(Flies are generally shot from above, which further complicates comparisons with your photo. Wing veins can be very important.)

 
Thanks Ron
for ID and extra information.

I always do try to take multiple views since I really don't which view will have the important information for the species. Sometimes they just get away.

How can you tell the gender of this fly?

Thanks again, I'm new here, some day I hope to know enough to help out.

 
Looks like my eyes aren't doing very well.
The example I linked to above is also female. Check these two images and the description on the first one.

Male, larger eyes:


Female:


On some flies, syrphids for instance, the male's eyes touch at the top. The way to seat this in your mind - or to double-check what's what - is to look for images of mating pairs.

Most people here - me definitely included - are eager to help. So ask away!

 
Interesting about male eyes b
Interesting about male eyes being larger. I wonder why males need larger eyes.

I do have another question about this fly. I am curious about the white patch under the wings of these flies(not the halteres).

Thank you for your generous offer to help.
I have to warn you that I'm famous for asking questions.
I'll try not to wear you out with too many !!

I only realized recently the enormity of insect taxonomy and how so much is still unknown.

I am so happy to have found this large community that loves insects.

 
Large eyes ... in the words of The Big, Bad Wolf...
all the better to see you with, my dear. (I suspect they're an aid in finding a mate.)

White patches are calypters; there's even a group of flies named after them. More here:

Glad you're here!

 
Thanks Ron
I'm learning so much here. Even flies are starting to look beautiful.

(Duplicated by the system. It wasn't me, honest.)
