Distinguishing morphological features of Order: Homoptera consist of mouthparts that are sectorial, formed into a beak, segmented, and rising from the back of the head. Homoptera have two pairs of wings, the wings consist of a leather or membranous, uniform texture, and at rest the wings are placed roof-like over the abdomen. Homoptera have antennae that are short and bristle-like or long and slender with 10 or less segments. The Aphid form of Homoptera are pear-shaped, have wings or wingless, with long antennae and consist of two posterior tubes called cornicles.


Ecological Importance: Aphids and plant hoppers are important plant diseases to control invasive species of plants or control the plant populations.


Economic/agricultural/human health importance: Some important contributions the Homoptera provide for humans include its secretion of lac. The lac is refined and used for shellac and varnishes. Aphids and scale insects of the Homoptera produce waxes that are used in candle wax, medicines, and candies. Some species of Scale insects of the Homoptera have been used for red dyes in clothing, food, and medicines.


Habits: Plant feeders and each species usually feeds on a particular part of a few species of plants resulting in discoloration, distortion, wilting, or stunting of the plant. A few homopterans cause the development of plant galls and sometimes death of plant.

Distinguishing morphological features of Order: Often has long antennae with 5 or fewer segments. Tarsi consists of 3 segments or less. Pronotum is usually large. Have sucking mouthparts that are formed into a beak arising from front of the head. Wings are usually held flat over back and overlap.


Ecological Importance: They can feed on plants or other insects and some are parasites. Some predaceous bugs are of value in keeping pest species under control.


Economic/agricultural/human health importance: Are considered pests to cultivated plants; a few are bloodsucking and irritating pests, and some are disease vectors to plants which hurts agriculture. They can also be parasites and transmit diseases to humans such as Chagas disease.


Habits:Members vary in habits; most are terrestrial but many are aquatic, and few are external arasitesof vertebrates. Many are plant feeders, and many are predaceous on other insects.
