Range & Status
Widely distributed in warm temperate regions, e.g. south-western Europe, the Canaries, California and South Africa (Pelham-Clinton, 1985). In Britain generally confined to warehouses and cellars (where it is continuously brooded) except on the Isles of Scilly.
Common on the Isles of Scilly on St. Mary' s, Tresco, St. Martin' s and St. Agnes, the only place in Britain where it is found in the open and also under the bark of Pittosporum bushes. (It is also found in the open on the Channel Islands).
Habitat & Ecology
Feeds as a larva in the open on dry vegetable matter (Emmet, 1991) and under the bark on Pittosporum crassifolium (Heckford, 1987), which has been widely planted on the islands as a windbreak. The adults fly from July to September. Little is known about its ecology.
