Contrary to the very common O. cerasi, the pronotum and elytra of O. lineola are pubescent. The species is distributed in Southern and Central Europe and develops in hawthorn (Crataegus), pear (Pirus) and plum (Prunus). According to Köhler/Klausnitzer (1998) there are no preceding records for Baden so far.

Record of Clitostethus arcuatus in the forest Dornhecke near Bad Schönborn (North Baden) in March 2008

On March 30th, 2008 the ladybird Clitostethus arcuatus was found in the forest Dornhecke near Bad Schönborn in North Baden on ivy. The very small (1.2–1.5 mm) and beautiful species is a predator of aphids (Aleurodidae). Clitostethus arcuatus is distributed in the Mediterranean region and is thermophilic. Accordingly in Germany it is mostly recorded from areas with favorable climatic conditions. Normally only single or a few specimen are found. However, under suitable circumstances, C. arcuatus can be found occasionally in abundance.
