Recent Status: Recorded across Suffolk but not common.
Life Style: The species is a single brooded species that flies from May to July and comes to light. The larvae live as an inquiline in ‘oak-apple’ galls feeding on the spongy material. The larvae hibernate fully fed in a cocoon in the gall.
Identification: The ground colour of the moth is chocolate brown. The face and palps are pale ochreous brown. There is a broad whitish sub-quadrate dorsal blotch that shows evidence of being composed of five short striae. The basal half of the wing is marked with plumbeous fasciae. The terminal half is marked with ochre, particularly between the whitish costal strigulae and either side of the ocellus, that is also edged with plumbeous grey. There are a number of similar Pammene species including P. agnotana, P. suspectana and possibly P. obscurana. All these species are present in Suffolk or adjoining counties but rare. If they are suspected then genitalia dissection is required. More Info
