Here is a gall and the weed I found it on--there were several on each plant, and, even though these weeds are very common, I don't know what they are. I was afraid that whatever came out of the gall might be too small to be restrained by netting, so I put the stem in a very small jar of water, placed it in a larger jar, and capped it. Because I do have a life apart from insects, I often forget to check jars each day. The result was a moldy weed, but I believe the insect, found dead in the jar on 09-10-10 is what came out of the gall.
