Otiorhynchus rugifrons (Gyllenhal, 1813)
Large blotch with dispersed frass in one of the lowest leaves; after a few days the larva moves through the petiole down and continues feeding on the roots. Pupation in the ground (Fox Wilson, 1925a).
According to Scherf (1964a) oviposition is on the ground, and only exceptionally an egg is deposited on a leaf. Also Rheinheimer & Hassler do not spend a word on a mining habit of this species.
