leaf mine - Phyllocnistis ampelopsiella

leaf mine - Phyllocnistis ampelopsiella
Cross Plains, Dane County, Wisconsin, USA
September 22, 2011
Mines found on the underside of a leaf of Virginia Creeper Parthenocissus quinquefolia. I think there may be two types of mines in this leaf. The white pupa (?) looked dark in the following photo which was taken several hours later. .

Now this is Phyllocnistis ampelopsiella for sure. Chambers said the mine of this species is found on the underside of the leaf, and that "though the mine is, strictly speaking, linear, yet it winds about from the midrib to the margin and back, between the veins of the leaf until the entire cuticle in the mined portion is separated, and the mine becomes a blotch." Your other mines that were on the upper side of Virginia creeper leaves

look pretty different, but I don't know of anything else that makes a linear mine on Virginia creeper, and it may just be that the mines look different when on occasion they are made on the upper side of the leaf. Another possibility, I suppose, is that those are Phyllocnistis vitifoliella mines on the "wrong" host plant. It would be interesting to get adults from those mines and have a specialist examine them.

 
I hope to be able to rear som
I hope to be able to rear some of these mines next summer.
