on Taraxacum officinale


Dandelions are non-native. Is the miner fly also? I see from another site that it will also mine other genera of Asteraceae, at least one of which is native American.

Not sure, but I suspect so
What's the other site you mention? I've only seen references to this species feeding on Taraxacum, "probably Cichorium intybus [also nonnative] and possibly some other genera of the Liguliflorae." (1)

UK fly mines

Well, given that the only documented hosts in North America are nonnative, I would presume that the fly is also. Owen Lonsdale could probably give a more informed answer. I've been wondering the same thing about Phytomyza crassiseta.
