Long-nosed Twist

The wingspan of female is 17–22 mm. and the male 15–20 mm. The long labial palps help distinguish this species from other tortrix moths. The moth flies in one generation from July to August.

Eggs are laid on the foodplant in batches of forty to sixty in July and August. Initially emerald-green, they change to greenish-yellow and later yellow. The eggs hatch in September and the larvae overwinter and continue to feed until May and June. They have a black head and prothoracic plate, with a pale green to greyish green body and a narrow darker green dorsal line. Feeding is within folded and spun leaves of various herbaceous plants and pupation occurs inside the rolled leaves.
