Winter moth larvae (caterpillars) emerge in early spring from egg masses laid near leaf buds after a series of days in which the daytime high temperatures reach around 10 °C (50 °F). [10] Recently hatched larvae feed on expanding leaf buds, often after having burrowed inside the bud, and later on foliage, for approximately six weeks.
The buds are a distinctive narrow conic shape, 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long, with red-brown bud scales. The leaves are spirally arranged but slightly twisted at the base to be upswept above the shoot, needle-like, 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, gray-green to blue-green above with a single broad stomatal patch, and with ...
