The flame brocade (Trigonophora flammea) is a moth of the family Noctuidae. The nominate subspecies T. f. flammea is found in Europe, mostly in the Mediterranean area up to Normandy. It is also found on the Channel Islands and it has spread to Southern England and Ireland. It is found in the Maghreb as the subspecies T. f. vividior. This also occurs in parts of Spain. The species lives primarily in dry areas, on warm slopes, grassy scrubland and in karstic oak.

Biology

Adults are on wing from October to November.

Larvae are wood brown mottled with grey; a row of diamond-shaped reddish brown blotches traversed by the pale dorsal line; tubercles black, with white centres; subdorsal lines pale, with fine dark edges; spiracles yellowish white.

The larvae feed on low plants such as Ranunculus in the early stages, later preferring such species as Fraxinus and Ligustrum.[2]

British Isles

Formerly, it was a resident in Sussex until becoming extinct there in the late 19th century.[3] In October 2011 however, The charity Butterfly Conservation reported that the moth has apparently become established in the south coast of England.[4]
