Anerastia

As a genus-level record, specific identification criteria are not applicable. Species within Anerastia are small to medium-sized pyralid moths with characteristic snout-like palps. Anerastia lotella specifically has sandy-brown forewings with variable speckles and streaks, and a distinct white costal streak.

Habitat varies by species. Anerastia lotella inhabits coastal sand dunes and inland grasslands, where larvae construct silken tubes at the base of grass stems. Other species' habitats are not well documented.

The genus is known from Egypt and Sudan (type region), with additional records from Denmark, Norway, and Sweden. Anerastia lotella specifically occurs locally in Britain, throughout Europe east to Russia, and in Canada.

Anerastia lotella is single-brooded and flies in July. Other species' seasonality is not documented.

For Anerastia lotella: larvae feed on grass stems and rootstocks, particularly Marram (Ammophila arenaria) and Sheep's Fescue (Festuca ovina). Feeding period extends from September through June. Diet of other species is unknown.

• Marram - larval food plantAmmophila arenaria, coastal dune grass
• Sheep's Fescue - larval food plantFestuca ovina

Anerastia lotella is single-brooded. Larvae live in silken sand-covered tubes at the base of grass stems and rootstocks, pupating in a cocoon at the base of the host plant. Life cycle details for other species are unknown.

Anerastia lotella larvae construct distinctive silken tubes covered with sand particles at the base of grass stems. Inland populations of this species often produce smaller, darker adults than coastal populations.

Anerastia lotella has been the subject of genomic research; a chromosome-level genome assembly has been generated from a female specimen collected at Winterton Dunes, Norfolk, UK, achieving EBP reference standard (6.C.Q61). No economic or agricultural significance is documented for the genus.
