Plant lice, Foto Fitis,


Aphids, or plant lice, are small insects that suck up plant juices. They secrete lots of honeydew, a sweet fluid. Ants in particular are attracted to this fluid. They even keep and guard aphids as if they were cows. Plant lice reproduce several generations in one year, in winged as well as wingless form. Many species cause characteristic growths (galls) on their host plants.
