Bucculatrix ainsliella mine



Tiny, full depth gallery, often in a vein axil, apart from the larval chamber almost completely filled with blackish brown frass. The mine starts at an iridescent egg shell next to a thick vein. Older larvae live free on the leaf, causing window feeding.

The mines often are a bit longer and less compact than those of Bucculatrix ulmella, that can live on the same host plant, but for a certain identification free living larvae must be looked for.

host plants

Fagaceae, narrowly monophagous

Quercus rubra.

In North America also on other “Red oaks”.


Free living larvae found in the Netherlands in early July.


BE recorded (van Nieukerken ao, 2012a).

NE recorded (van Nieukerken & Doorenweerd, 20011a).

LUX not recorded (Fauna Europaea, 2011).

distribution within Europe

North American species, Nieukerken in 2011 discovered at several localities in the Netherlands and Belgium; probably also in Germany.





In North America a forest pest; how the expansion of the species in Europe will develop is an open question.
