The 2.1 to 2.7 mm large weevil Ceutorhynchus scapularis (family Curculionidae) is one of the approx. 60 representatives of the genus in Germany. The conspicuous squamation of the pronotum allows a relatively easy determination of the species in the otherwise often difficult genus. C. scapularis occurs in Scandinavia, Central and Eastern Europe to Siberia. The stenotopic, ripicolous species lives on sandy edges of lakes and riverbanks and drying-up cut-off meanders. It develops oligophagous on Greater Yellowcress (Rorippa amphibian) and occasionally on Bog Yellowcress (R. palustris). The beetles can be found near their host plants from April on, but don't climb up the plants and can be found only by systematic search. Known from most Federal States in Germany but rare and regarded as near threatened (RL V). (CB)
