FAMILY PENTATOMIDAE: SHIELD BUGS
Instantly recognisable on account of the large triangular shield-shaped scutellum, the Shield Bugs or "Chinches" as they are known locally, are one of the most charismatic of heteropteran families. The body is rounded, tapering towards the rear and often with two "horns" on the pronotum. With a lateral view the dorsal surface appears flattened and the ventral surface convex. The small head carries antennae with up to five segments and often appears to be sunk below the broad pronotum. The legs are sometimes hairy or bristly but never spiny and the wings are well-developed for fast buzzy flight, with a maximum of 12 distinct veins in the membranous rear portion. Shield Bugs are well known for their ability to produce strong-smelling secretions from the thoracic glands of adults (or abdominal glands of nymphs) - hence the alternative common name Stink Bugs. These secretions are species specific and consist of organic volatile chemicals designed to perform a defensive function. Most Shield Bugs are vegetarian, sucking sap from shrubs and trees and some species show brood care behaviours. We highly recommend that anybody interested in this group check out Dr David Rider´s Pentatomoidea Home Page for further information.
