Helcystogramma lutatella (Herrich-Schäffer, 1854)

Wingspan: 12-18mm

A bivoltine species on the wing from May to the end of August when it is a scarce visitor to the lights of Las Descargues and the Causse despite being a species of limestone habitats.

Larvae feed on Calamagrostis epigejos, Dactylis glomerata, Elystrigia repens and Phragmites australis. Pupation takes place inside a silky cocoon not used for feeding.
