Mine Comment: The larvae create a distinctive blotch mine on the underside of a birch leaf, often small but puckers the leaf noticeably. The mine is small (8-14 mm long) and causes the leaf to pucker noticeably, often resulting in several (can be up to 6) creases in the lower epidermis. A small lower surface tentiform mine and all frass is in a corner of the mine.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
