Blotch-mining agromyzid on dayflowers (Commelina spp.)
I'm using this post to organize information about an unknown species that is widespread in eastern and central North America, making communal blotch mines at the tips of Commelina leaves. So far I have been sent adults reared in Nebraska (but in poor condition), and adults have been reared in Texas but not sent to me; additional specimens would be most welcome!
