Hemiptera is an order of insects called a true ladybug, although some Hemiptera members are not a true ladybird. They all have special features such as a needle-shaped mouth that is used to puncture the tissue from its feed and then suck the liquid in it.
Another feature is that Hemiptera does not have perfect metamorphism. In these newly hatched insects usually have the same appearance with the mother, but the size is smaller and not winged. This seedling phase is known as nymph. Hemiptera nymph is then doing the skin replacement many times until finally become adults without going through the cocoon phase.
here's my simple explanation, hope you like it.
