\n<\/p>\n


\n<\/p>\n

mine<\/h3>\n

Almost round, brown to brownish black, upper surface, very opaque blotch, about 1 cm in diameter, without an initial corridor. Upper epidermis leathery in colour. Often several mines in a leaf. All frass as a tar-like film on the floor of the mine. Egg shell at leaf underside, difficult to see, hyaline. Larva solitary. Pupation in the mine; pupa not in a cocoon.<\/p>\n

<\/p>\n


\n<\/p>\n

BE in 2008 bred from Salix<\/em> by Jorgen Ravoet; det. Theodoor Heijerman; see also Curuculionidae.be (2010).<\/p>\n

\n<\/p>\n

notes<\/h3>\n

Hering (1957a) describes the species as very common and numerous; this is not generally true in the Netherlands, although it may suddenly be locally abundant on pollard willows (van Frankenhuyzen & Freriks, 1986a).<\/p>\n
