mine

Usually a very small (but see below), pear-shaped, upper-surface blotch, most of it stuffed with reddish-brown frass. Often several mines in a leaf. Oviposition is already in May, but the larvae hatch late and initially develop very slowly; only against the end of summer the mines become apparent. The larvae remain the the mine: they hibernate in the fallen leaves (van Frankenhuyzen & Freriks, 1969c). The bright-coloured frass and their large number makes these mines very conspicuous in autumn, despite their small size. The weevils feed pinhole-sized windows in the leaf upperside (maturation feeding).

Mainly on hawthorn the mines take a quite different aspect in the autumn. Then they are comparatively large, full depth blotch mines with granular, black, dispersed frass.
