49.195 Marsh Lance Bactra furfurana (Haworth, 1811)


Similar species:

Forewing: 6 to 9mm

Habitats: Marshes, fens, pond margins, bogs, coastal brackish marsh and coastal landslip.

Habits: The moth rests low down on the vegetation, but flies from the afternoon onwards in warm weather. It comes to light.

Foodplant: The larva hollows out the stems of Compact Rush and Common Spike-rush, leaving much green frass and moving to another stem if more food is required. The feeding often causes the stems to go brown or collapse. It pupates in a flimsy cocoon in a stem of the foodplant.
