Cantharis obscura / Cantharis paradoxa
Another typical Sailor Beetle is Cantharis obscura. In order to identify it pay attention to the fact that it is all black, except for the edges of the neck shield which are red. Alas there are two identical species around, which can only be told apart by examining their genitals: Cantharis obscura and Cantharis paradoxa. The larvae live in oak mainly, but are often found in orchards as well. They may be harmful to the trees, when there are a lot them. But not only do they eat fresh leaves, they hunt for aphids and other small insects as well. Once adult they measure some 9 to 13 mm. in length. The adults have the same diet as the larvae have. both species are common all over Europe, including Scotland.
