Bactra robustana

(Christoph, 1872)

Wingspan c. 16-22 mm.

This species is to be found in saltmarshes around the coasts of southern and western England and Wales, where it can be locally common.

Habitat is a good indicator of the species, but it does closely resemble other Bactra species, and therefore genitalia dissection may be necessary for confident identification.

The flight period is June and July, and the moths can be attracted to light.

The larvae feed internally in the stems of sea club-rush (Bolboschoenus maritimus).
