Usually reaching a length of some 4mm Campyloneura virgula is very small indeed. Characteristic are the two small yellow dots on the front wings, just before the hardened part ends. One rarely gets a good look at it, for it is one of the swiftest runners among the plant bugs. However every now and then it might bite a human, thus exposing itself for a while. The curious thing about this species is that we hardly ever see a male. It is speculated that this species reproduces without mating. It is a predator that hunts for small insects, including aphids and red mites. It is the adult overwintering. Campyloneura virgula is a common species on numerous deciduous trees all over Europe, including all of the British Isles. Has been introduced to the United States of America, where it is well established on the West Coast.
