Cionus olens (F., 1792)
Cionus olens
The weevil Cionus olens (family Curculionidae) is one of a total of twelve species of the genus in Germany. Contrary to other species of the genus, Cionus olens is easily determined by the conspicuous, long and erect pubescence of the elytra. The distribution of the stenotopic and thermophilic species ranges from Western over Southern Europe to Anatolia. In Germany, recent records of Cionus olens exist from the western Federal States (from Baden to Westphalia). The 3.5 to 4.2 mm large species can be found on warm and dry mountain slopes and fallow land. It develops oligophagous on different Verbascum species, mainly on Orange mullein (V. phlomoides), rarely on Dark mullein (V. nigrum) and Hoary mullein (V. pulverulentum). In Germany, Cionus olens is regarded as vulnerable (RL 3). (CB)
