A suborder of Hemiptera, in which the base of the anterior wings is thickened. See Hemiptera.

Heteroptera is a group of about 40,000 species of insects (also called true bugs) in the order Hemiptera. The word "Heteroptera" is Greek for different wings: most species have forewings with both membranous and hardened portions (called hemelytra); members of the primitive infraorder Enicocephalomorpha have wings that are completely membranous.
