Sonchus asper, Amstelveen, 27.viii.2007: two vacated mines, lower surface

a young larva in its mine

mine

Circular, lower-surface blotch, about 5 mm in diam, often quite a number together on a leaf. Upper surface wart-like, strongly reddish discoloured, opaque. At the lower surface the mine is closed only by the epidermis. The larva is easily visible, as is its food: drops of liquid resulting from external digestion. Pupation sometimes in the mine, sometimes in the soil. At least two annual generations. Pupa in a white cocoon (Löw, 1888a).

host plants

Asteraceae, monophagous

Sonchus arvensis, asper & subsp. glaucescens, maritimus, oleraceus, tenerrimus.

phenology

Larvae from July on (Hering, 1957a); two or more generations per year, pupation of the summer generation(s) in the galls, pupation of the winter generation in the soil (Bayram, Skuhravá & Çobanoğlu (2005a).

BE recorded (Gosseries, 1991c).

notes

The biology of Cystiphora species forms a transition between the mining and galling ways of life.
