Ectoedemia subbimaculella - Ectoedemia subbimaculella

Alt Name
Spotted Black Pigmy
Description

Wingspan 5 to 6 mm. The adults are similar to E. heringi  but otherwise quite distinctive, with two creamy spots and a creamy basal patch on a violet-tinged blackish forewing.

Habitat

Around Oak.

When to see it

Adult: May to July.

Life History

The larvae mine Oak leaves, initially in a gallery following a vein, then creating a triangular blotch between vein and midrib. It can be distinguished from the similar mines of E. heringi by the presence of a slit in the lower epidermis which allows frass and water to pass.

UK Status

Commonest in south-east England, the distribution expands north and westwards. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.

VC55 Status

Occasional in Leicestershire and Rutland. L&R Moth Group status = C (very scarce resident or rare migrant). It is probably more common that this rating suggests as its tiny size and difficulty of identification probably means that the species is under recorded.
