This is a species of Calycomyza. I might be able to tell what species it was if I knew the plant - not as reliable as a rearing record, but these agromyzids are known to stick pretty close to their hosts.
Not a lot is known of the biology of these flies, so field records like these could be invaluable.

The plant that i found this fly on is one that many insects love in my yard its Axocatzin. Hope this helps.

Thanks Eric, now, do these eat leaf miners or are these the insects that leave all the squiggly designs on the leaves? If you don't mind me asking.
