Hemiptera (Bugs)
-
Include aphids, scale insects, leaf hoppers and cicadas
Feed on plant juice, thus they are not of public/veterinary importance
But, very important agricultural pests
-
The true bugs have forewings that are hardened at the base and membranous at the tips.
They sit flat over the abdomen hiding the membranous hind wings.
The head and proboscis can flex forward.
Most suck plant juices, many are predatory, using their mouthparts to suck body fluids of smaller arthropods

Mouthparts & Feeding
Both homopterans & heteropterans have similar basic mouthparts (regardless feed on plant or animal juices)
-
Hemipterans feed by cutting into a plant or animal and sending saliva down one of the tubes to begin digestion.
