Monochroa robusta

It is found in North America, where it has been recorded from Ohio and South Carolina.

The forewings are dull ocherous, rather densely overlaid with purplish fuscous dusting, especially toward the apex, where it obscures the ground color.

At two-thirds a not very oblique yellowish costal streak passes to the middle of the wing just beyond the rather elongate black spot at the end of the cell.

Following this is a linear green portion with sides nearly parallel, in which the leaf substance is not eaten.

When ready to pupate, the larva leaves the mine through a circular hole in the upperside of the linear green portion.
