The Traveller Costaconvexa centrostrigaria

(Wollaston, 1858)

Wingspan c. 22mm.

There is only a single record of this American species in the British Isles, an individual that came to light in Middlesex in June 1973, although it was not correctly identified until 1999. It is believed that the occurrence may be due to accidental importation.

Adults superficially resemble the Many-lined, C. polygrammata, although there are subtle differences in the shape of the transverse lines and the central spot on the forewing is larger and more conspicuous.

As well as the Americas, it also occurs in Madeira and other Atlantic Islands. In its native haunts, the larva feeds on low plants.
