bugs (including the shield bugs), have their wings
divided into two parts:
- the toughened basal part
which consists of the corium, clavus and cuneus. There
are 'fractures' between these areas which give flexibility to the wing.
- the distal part which
consists of the hemyletral membrane (the clear tip).
Homopteran bugs -
froghoppers and treehoppers
Instar: the larval stage
between two successive skin moults. There are several instars and the
larva may have an entirely different pattern or colour during each instar.
Legs: consisting of
fore-legs, mid-legs and hind-legs. Each of these is divided into the coxa,
trochanter, femur, tibia and tarsus.
Ocelli: these two
organs on the top of the head are simple eyes (some Hemiptera have three).
Pronotum: this is
the large structure saddling the thorax. In many of the shield bugs it is
widened into large thorn-like extensions.
