The Hawthorn Shield Bug (Heteroptera)
has been used to illustrate the anatomy of the Hemiptera. The Homopteran bugs do
not have hemyletral forewings and their wings are held
over their abdomen in a tent-like manner, not flat as in the Heteroptera.
Antenna: these are
segmented and vary in the number of segments according to the family.
Clavus: the inner part of the
wing adjacent to the scutellum of the heteropteron bugs.
Compound eyes: two
Corium: the main central area
of the toughened and opaque base of the forewing of heteropteron bugs.
Coxa: the first segment
(from the body) of the leg.
Cuneus: the most distal
part of the toughened and opaque base of the forewing of heteropteron bugs.
Dorsal or Dorsum:
the upper surface of the insect.
Femur: the third
section (from the body) of the leg.
