Caenocoris nerii is a bug from the family of ground bugs (Lygaeidae). In English, the type of bug bears the name Oleander Seed Bug (German: "Oleander seed bug ").
features
The slender bugs are 7.5 to 9.5 millimeters long, with the females being on average larger than their male counterparts. The bugs are black and red in color. The abdomen is colored red. The head is red on the sides and back, otherwise black. The antennae and legs are completely black. The otherwise black pronotum has a red border on the sides. There are two black triangular spots at the base of the scutellum . The apical half of the scutellum is colored red. The hemyelytres also have a red-black pattern: the basal corners are red. The edge of the clavus and cuneus beginning at the tip of the scutellum is also colored red. Otherwise the hemielytras are black. The membrane is dark. This does not always cover the abdomen completely.
distribution
The species is common in the European Mediterranean area. Their occurrence ranges from the Canary Islands in the west over the Iberian Peninsula and the northern Mediterranean coast to Cyprus. Furthermore, the species occurs in the Afrotropic as well as in the Oriental .
Way of life
The species uses the oleander ( Nerium oleander ) as the main host plant . The females lay their eggs in larger packages on its leaves. The different nymph stages feed on the sap of their host plants and overwinter. The release in spring and early summer imagines feed mainly on fruits and seeds of the oleander plant. Because of their warning color and the toxins they ingest with their food, the bugs are avoided by possible predators.
