Foodplant and Larval Feeding Signs

Said to feed on lichens on tree trunks although this reference appears to relate to observations in Europe in the first half of the 19th century and subsequently repeated by Stainton, Meyrick, Emmet and Langmaid. A reference to the larva having been found in Britain has, so far, not been located.


Woodland, with a suggestion it is associated with ancient broad-leaved woodland.

Finding the Moth

Larva: feeding signs might be found on lichens on the trunks of mature broad-leaved trees in old woodland or on the trunks of long-established fruit trees.

Adult: rests on tree-trunks by day and comes to light and sugar by night.

Similar Species

Superficially similar to the two Neofriseria species but can be readily distinguished by the pale-tipped brownish-black labial palps and the forewings which are more pointed and have obvious pale creamy-white patches beyond each of the three prominent black stigmata.

July, August

Single brooded, flying in July and August.
