The woolly apple aphid, Eriosoma lanigerum is a widespread pest of fruit trees, feeding principally on apple, but also, pears, hawthorn, ash, alders, elms and oaks. Gall making species include Melaphis rhois and Pemphigus spp. Further minor damage can be caused by the honeydew that woolly aphids secrete, which is difficult to remove.
Like other true bugs, Dysdercus cingulatus sucks fluids from its host plants. The only part of the cotton plant affected by this pest is the flower and the seed capsule or boll. As this develops, the insect thrusts its rostrum between the carpels and sucks fluids from the still soft seeds inside. Micro-organisms are admitted in the process and ...

Species may be confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. They can be readily distinguished from most other genera of Pyrrhocoridae by the strong white markings at the junction of the head and thorax, and along the sides of the thorax, and often abdomen.
