Morley’s Final Catalogue: Found at Ipswich about 1900 (Pyett); in profusion on oak trunks at Tuddenham before 1890 (Warren).
Recent Records: The species is common in Suffolk.
Life Style: A single brooded species that flies during June and July. The larvae feed on deciduous Quercus species. They pupate in a cocoon on the ground.
Identification: The moth is very similar to E. heringi. They have an orange head tuft and white scape. The black wings have white at the base, a spot centrally on the costa and a spot beyond this on the dorsum. The cilia and the sides of thorax are white. They can be separated by genitalia dissection. The larva creates a narrow gallery from the oviposition site on the upper surface of a leaf. The gallery follows a vein before becoming a blotch. E. subbimaculella usually cuts a slit in the lower epidermis allowing frass to escape. E. heringi does not. The larvae are similar but that of E. subbimaculella has a darker and less reddish brown head and prothoracic plate than E. heringi. More Info
Verification Grade Comment: Underside epidermal slit must be shown
