Alternative names
Winter Oak Groundling

Wingspan about 14mm. Although quite variable in intensity of markings and depth of ground colour, this species generally shows a distinctive black bar at the base of the forewing leading edge, a good identification pointer.

Identification difficulty

When to see it

Life History

The larva feeds inside a folded leaf of oak or dogwood.

UK Status
