To the guy who said true bugs belong to order Hemiptera, you are technically right, however, there is more detail than that. True bugs are actually suborder Heteroptera in order Hemiptera. Some examples of Heteroptera are stink bugs (Pentatomidae), bed bugs (Cimicidae), water striders (Gerridae), and assassin bugs (Reduviidae). Some examples of Hemiptera that are not true bugs are cicadas (Cicadidae), aphids (Aphididae), and leafhoppers (Cicadellidae). These are classified under suborders Sternorrhyncha or Auchenorrhyncha.
