Eriocrania
Birch leaf-mining moths
Eriocrania is a Palearctic genus of small, diurnal leaf-mining moths in the family Eriocraniidae. Adults are active in early spring (March–May), flying in sunshine around host trees. Larvae are specialized miners of birch leaves (Betula spp.), forming large blotch mines with distinctive frass patterns. The genus exhibits pronounced population fluctuations between years and has been extensively studied for its ecological interactions, including competition with other leaf-miners and responses to environmental stressors such as urbanization and pollution.
