Leaf miner, Jacob's ladder - Coleophora polemoniella

Yellow River State Forest, Allamakee County, Iowa, USA

Detail, mines

For this image, I peeled back the outer layer of leaf tissue to expose a dark oval object inside the mine (at upper left)...a dead larva maybe but it's impossible to tell for sure

It almost looks like their might be two separate mines in this image...a thin, tortuous whitish mine (right side of image) and a broader, fainter mine (left side of image)

Will have to keep an eye out next year so as to sort this out.

Moved from Unidentified Leaf Mines.

Not sure what the mine on the left might be.

Braun 1919

Describing Coleophora palemoniella for the first time, in 1919, Annette Braun wrote: "The larva is yellow and makes a very fine whitish transparent thread-like mine, much contorted, which at last encloses in outline a slightly flattened ellipse,--that portion of the leaf which is to be cut out to form the case. The portion cut out measures 2 mm. by 1 mm. This piece, in which the parenchyma is not consumed, forms the foundation for the case." (p. 128)
