Food Plant: Silene nutans (Nottingham catchfly)

Mine: September-July

Notes: Found on shingle beaches and also chalk cliffs on the Kent coast. The eggs are laid on the plant in August-September and the larva feeds in the autumn and overwinters. Heckford & Beavan (2022) showed that this initial pre-hibernation larva feeds on the leaves of Silene nutans and that the initial case (as shown) is not made from seed husks or seeds, contrary to some publications. The final case is about 12mm long and many may be found on a single plant. This case has distinctive longitudinal stripes.
