Stigmella suberivora
Plain Holm Oak Dot

Wingspan c. 6mm.

A bivoltine species with larvae mining leaves of Evergreen Oak (Quercus ilex) during mid-summer and again during the winter-spring period.

It is found mainly in southern England but apparently rather local.

The eggs are laid on the upper surface of the leaves, and the yellow larva creates a fairly broad mine almost filled with frass.

The adults are dark grey/blackish with a faint purplish tinge and a yellow head.
