Fly from stinging nettle dead stems - Melanagromyza martini

Fly from stinging nettle dead stems - Melanagromyza martini
Winneshiek County, Iowa, USA
June 13, 2016
Three of these flies have emerged so far from my batch rearing of dead stems of stinging nettle, Urtica dioica. I have torn into several stinging nettle dead stems (not part of the rearing) and found fly pupae inside, especially in the bottom 12" or so of the stalk, where it is very thick.

One of the other flies from the batch rearing:

Moved from Melanagromyza.

This species was described by Spencer (1969) and was only known from Canada until 2015, when it was documented in California by Shi & Gaimari. So that's why it's missing from the USDA manual.

 
And thank you
for making the page. Nice to have a species page under Melanagromyza now!

 
Ah!
Interesting, thx :)

One possibility
According to the manual of Agromyzidae, only Melanagromyza urticella is known from stems of Urtica dioica.

 
Hi again John
The publication I found is here (there is a link to the full text on the webpage):

http://dx.doi.org/10.11646/zootaxa.4005.1.1

The authors redescribe M. urticella on pp. 82-85, with some nice photos on p. 83. The wing looks to be a pretty close match from what I can tell. Also the authors describe the haltere as follows: "Halter with stem pale brown and knob brownish black." Seems like a match with this picture (of another specimen from the same batch rearing):

 
Thanks, John
That would be a new sp. for BG and Iowa! I have found a paper with some nice pictures of that species, and when I have time (hopefully in the next few days) I'll compare it with my specimen pictured here.
