Pentatomidae, Greek pente meaning five and tomos meaning section, are a family of insects belonging to order Hemiptera including some of the stink bugs and shield bugs.
There are several subfamilies, of which the Australian Aphylinae is often given family status, but is here retained as a subfamily, following Grazia et al. (2008).
The scutellum body is typically half of an inch long, green or brown color, usually trapezoidal in shape, giving this family the name "shield bug". The tarsi are 3-segmented. The forewings of stink bugs are called hemelytra, with the basal half thickened while the apex is membranous (as are the hindwings).
The stink bug derives its name from an unpleasant scent from a glandular substance released from pores in the thorax when disturbed. The chemicals involved include aldehydes, making the smell similar to that of coriander. In some species, the liquid contains cyanide compounds and a rancid almond scent, used to protect themselves and discourage predators.
The term 'stink bug' is also used in referring to the distantly-related species Boisea trivittata and to some unrelated insects, including beetles in the genus Eleodes such as the Pinacate beetle.
Many stink bugs and shield bugs are considered agricultural pest insects, because they can create large populations which feed on crops (damaging production), and they are resistant to many pesticides. They are a threat to cotton, corn, sorghum, soybeans, native and ornamental trees, shrubs, vines, weeds, and many cultivated crops. However, some genera of Pentatomidae are considered highly beneficial: the anchor bug, which can be distinguished by the red-orange anchor shape on the adult, is one example. It is a predator of other insects, especially Mexican bean beetles, Japanese beetles, and other pest insects.
Some also are commonly eaten in Laos, and are regarded as delicious due to their extremely strong odor. The insects are sometimes pounded together with spices and a seasoning to prepare cheo, a paste mixed with chilies and herbs.
