Moved
Moved from Phytomyza.
Owen Lonsdale says he has records of P. syngenesiae from Saskatchewan and Ontario in the Canadian National Collection, so Wisconsin seems perfectly plausible.

Did you happen to get a shot of the underside?
The only known linear mines on Cirsium are from Liriomyza species, but the frass pattern looks like Phytomyza. I'm wondering if there might be a puparium hidden under the lower epidermis.

They're pretty sneaky!
Well, time to go edit my Asteraceae chapter again... this is probably Phytomyza syngenesiae, but this introduced species apparently hasn't been reported from anywhere between Alberta and Massachusetts.
