Segmentation of the body is indistinct, but may be indicated by the presence of marginal bristles. This rich food source does not go unnoticed. As scale insects feed on the sap of a plant, they excrete tiny droplets of a sugary liquid called honeydew. Besides sexual reproduction, a number of different forms of reproductive systems are employed, including asexual reproduction by parthenogenesis.

[2] For example, cochineal species are restricted to cactus hosts, and the gall-inducing Apiomorpha are restricted to Eucalyptus. Scale insects (Hemiptera spp.) In Iowa, most species of shade trees, fruit trees, and ornamental shrubs are subject to scale insect attacks. On the University of Florida / Institute of Food and Agricultural Sciences Featured Creatures website: Reproduction and the genetics of sex determination, "The evolution of hermaphroditism by an infectious male-derived cell lineage: an inclusive-fitness analysis", "Large population size predicts the distribution of sexuality in scale insects", "Which host-dependent insects are most prone to coextinction under changed climates?
