Monthly Mystery #19: Aster Leaf Tubes
As I mentioned here, I normally can’t be bothered with leafrollers, leaftiers, etc. Not so much because the thousands of leafminers (not to mention gallmakers) in North America are enough to keep me busy for a while as because what … Continue reading

Flies from a Goldenrod Leaf
As part of my survey of gall-making and leaf-mining species of Nantucket last summer, I collected a number of Elliott’s goldenrod (Solidago latissimifolia) leaves with mines like this one: Beginning three days later, agromyzid flies emerged from these mines over … Continue reading

Ovipositors
In one of my first posts, I wrote about some goldenrod rosette galls I collected and the things that were emerging from them. I pointed out how this female torymid wasp could be recognized by her long ovipositor, which allows her to insert … Continue reading
A Flurry of Emergences
I had four different insects emerge (or try to emerge) yesterday, and I think I’ll just show them all here rather than make four different posts. First, to follow up on my last post, another Tischeria quercitella mine yielded an … Continue reading

Goldenrod Ball Galls
