Agromyzid in developing columbine fruits - Phytomyza krygeri

Agromyzid in developing columbine fruits - Phytomyza krygeri
Battle Bluff Prairie SNA, Vernon County, Wisconsin, USA
June 5, 2017
06/03/17 Noticed damage to fruits of wild columbine plants growing on a hill prairie; agromyzid puparia inside the fruits, among the developing seeds. Puparia are about the same size and shape as the seeds and could easily be mistaken for them -- but the damage to the exterior of the fruits seems unmistakable. Collected for rearing

Rearing in progress

Moved
Moved from Phytomyza.

I had two adults emerge yesterday from the seed capsules I collected last June, and they look like the flies illustrated in Owen's paper.

Moved from Leaf Miner Flies.

Definitely something interesting... good luck with the rearing!

Nothing yet, fingers crossed.

Possibly Phytomyza krygeri
Owen Lonsdale has cited this photo in his paper documenting this European species in North America for the first time. I found similar damage to columbine across the road from my house, which is also mentioned. The puparia apparently overwinter in the pods and adults emerge the following spring; if we're unable to rear them, the best bet is to look for adults on flowers.
