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.
