Homoptera
Homoptera is an order of insects characterized by their sucking mouthparts, which are used to feed on plant sap. This group includes aphids, cicadas, leafhoppers, and scale insects, among others. Homopteran species vary greatly in size, coloration, and behavior, but they share certain features such as having two pairs of wings, with the forewings typically being harder and more heavily veined than the hindwings. Many homopterans also have a complex life cycle involving multiple nymphal stages and, in some cases, asexual reproduction through parthenogenesis. The order Homoptera was traditionally recognized, but it has been merged with the order Hemiptera in many modern classification schemes due to their close evolutionary relationship.
