    Habitat

    The lower slopes of mountains and glens in sheltered south facing areas adjacent to or amongst open woodland, but apparently not on juniper plants under trees.

    Finding the Moth

    Larva: in a silken spinning amongst the needles. The species has a mixed development strategy with larvae being fully fed by early September (occasionally pupating by then). Alternatively the species will overwinter as an egg or small larva (currently not known which), feeding up in the spring until June.

    Adult: can be beaten from the foodplant and is attracted to light.

    Similar Species

    The distinctive palps, pale greyish forewing colour with black outer edging along the termen and a few black central spots are distinctive.
