emiptera is an order of insects that is also known as a true ladybug (although some Hemiptera members are not a true ladybird
Aquatic Hemiptera includes semi-aquatic Gerromorpha bugs that live mainly on the water surface and water fleas (Nepomorpha) that live submerged underwater along with several other terrestrial groups living near aquatic habitats. Over 4,800 species described from aquatic Hemiptera occur in all continents except Antarctica, and occupy a diversity of habitats ranging from lakes and rivers to seasonal rain pools. Taxis can be large (up to 11 cm), and most are predators in other insects or occasionally vertebrate prey. Aquatic Hemiptera evolved terrestrial and secondary-invaded water habitats. This terrestrial spatial plan has influenced the evolution of Hemiptera
Most hemipterans feed on plants, using sucking and poking mouths to extract plant sap. Some are parasitic while others are predators that feed on other insects or small invertebrates. They live in a variety of habitats, generally terrestrial, although some species adapt to life on or on the surface of fresh water. Hemipterans are hemimetabolous, with a slightly resembling young nymph
As a plant feeder, some bugs - like aphids, for example - are serious agricultural pests, not only because they damage crops but because they can transmit viral diseases as well. However, most bugs are not pests
The actual bug often has a long antenna divided into a small number of segments, and the front wing can be slightly hardened. Some bugs resemble beetles, but beetles have an overlapping wing cover, unlike bugs
The Heteropteran Bug has an obvious front wing split into two regions, a hard and rough basal area and a membrane tip, and a membranous rear wing; the four wings are folded over their backs when not needed to fly.
Homopteran insects have hard or membranous wings (but not both) front and fourth wings like a tent above the body when insects are resting
