Large blotch mine on the upperside of Broad-Leaved Dock Rumex obtusifolius.
No interactions present.
They can't, and not even from the larvae in the mines. I keep meaning to make the effort to rear some, but so far have not found the time.

I am going though all the posts of Pegomya (solennis).
I believe it unwise to agree to pictures of mines in plant tissue without fairly strong supporting evidence.
Note that Rob, who knows a thing or two about Leaf Miners, has agreed to the genera only here. There are VERY few agreements in leaf-miner posts
When posting my own, I usually go through other posts of these (obscure) observations - there are never many in Other Observations. I feel compelled to offer comment and be generally supportive and encouraging whenever possible.
For my post of today I looked at every other one in iSpot - a useful exercise.
Now see http://www.ispotnature.org/node/817566 - an hour's work.
