Nutrition:
The species feeds on grasses, herbs and also captures small insects.
Habitat:
Conocephalus dorsalis colonizes wetlands. It occurs in reed edges, on bins rich fen meadows and in ditches.
Life cycle:
The eggs are deposited in blades, leaf sheaths and stems (Phragmites, Juncus, Carex, etc.), where they hibernate. The larvae hatch in spring (May). Adults usually occur from late June to October.
Endangerment: endangered
Endangerment factors:
Conocephalus dorsalis occurs particularly (but not only) in large marsh complexes and is accordingly threatened by habitat loss.
Remarks:
Conocephalus dorsalis occurs especially from France and Great Britain across Central Europe to western Siberia. In the north they reached Southern Scandinavia, in the south Southern France, Corsica, Bulgaria, Northern Italy and extremely locally Southern Spain.
