    Foodplant and Larval Feeding Signs

    Juniperus communis (common juniper), see plant distribution, and garden species and cultivars, including Juniperus squamata 'blue carpet'. Found once on Chamaecyparis lawsoniana (Lawson's cypress).

    Mines a needle in the autumn, overwintering in the mine. In the spring spins an extensive, dense silk web amongst the needles which may occasionally contain more than one larva.

    Chalk and limestone areas where Juniper occurs, and occasionally in gardens where suitable cultivars occur.

    Finding the Moth

    Larva: best found by looking for the distinctive dense silk web in the spring.

    Adult: can be beaten from the foodplant and comes readily to light
