Linear/blotch mining, white snakeroot - Leucospilapteryx venustella

Linear/blotch mining, white snakeroot - Leucospilapteryx venustella
Chattahoochie Park, Winneshiek County, Iowa, USA
September 27, 2017
Very small larva creating rather faint underside blotch mine on white snakeroot, Ageratina altissima, with some linear mining associated (maybe the linear mining is a fluke?); the mine I'm wondering about is left of the midvein in this image

Another example


I wonder if this could be an early stage mine of Leucospilapteryx venustella, with the leaf buckling later, like what's shown in this series

or like the buckled area to the right of the midvein here.

Rearing in progress

Moved
Moved from Unidentified Leaf Mines.

Not a fluke; the mine is always initially linear but that part is sometimes later obliterated (and the larva may be able to exit and form a new blotch mine elsewhere).

 
Very interesting
Thank you!
