True bugs include insects such as leafhoppers, aphids, cicadas, stink bugs, water bugs and bed bugs. They have many of the same parts as other insects in that they have an exoskeleton, segmented bodies, and six legs. However, when they reproduce all true bugs hatch from their egg as a miniature version of the adult bug. The front wings of true bugs are thickened and colored near where they are attached to the insect’s body, and are clearer and thinner towards the hind end of the wing. It is important to remember that all bugs are insects, but not all insects are bugs.

The key difference between true bugs and other insects is their mouthparts. True bugs have specialized mouthparts that look like a long beak and work much like a straw to suck juices, allowing them to move food from the source to their mouth. A plant-feeding true bug pierces the leaf, stem, or other plant part with its beak and sucks the plant juices up its food channel. Many bugs feed only on a certain kind of plant. Mostly they suck fluids from plants, but there are some true bugs, like bed bugs, that feed on animals. In addition to plants, some bugs feed on algae and fungi
