Insects use a variety of defense mechanisms to avoid predation, including chemical defenses, running, flying, mimicry and camouflage. However, these are only a few of the tactics and strategies employed by the group as a whole.Know More
North Carolina State University explains that when a predator grabs a leg of some insect species, such as crane flies, the insect can break off the appendage. Called autotomy, this technique is also employed by walking sticks, grasshoppers and other long-legged species. Some insects regenerate their lost limbs, but even among those that don't, the missing appendage usually isn't a serious burden.
Other species, particularly a number of caterpillars, use bristles, spines or hairs to defend themselves. Some of these hairs dissuade predators through mechanical means. Contrastingly, other hair types, such as the spines of saddleback caterpillars, induce pain or itching upon contact. Such structures are called urticating hairs.
Other insects, such as the familiar wasps, bees and ants, produce venom that is delivered through a hollow stinger. Located at the back of the abdomen, these stingers are actually modified ovipositors. The venom used by these insects often causes pain, but, in some cases, it can also cause an allergic reaction in the predator.Learn more about Bugs
Scorpions are neither insects nor spiders; they are distant cousins of the spider and are animals in the Scorpiones order, beneath the class Arachnida. Unlike insects that have six legs, scorpions and spiders both have eight legs, and scorpions have only two body segments, compared to the insects' three.Full Answer >
Stick insects, despite their imposing appearance, are herbivorous. There are over 3,000 different kinds of stick insects, collectively called phasmids, and all of them eat plants. Some are very specialized, feeding only upon a favored plant species. Others are generalists.Full Answer >
Drywood termites are classified as insects and fall into the order of Blattodea along with other termites and cockroaches. They belong to the family Kalotermitidae, which separates them from other species of termite.Full Answer >
Millipedes eat decaying plant materials and wood particles, and they sometimes eat decayed animals like insects, earthworms and snails. If their habitats dry out, millipedes tend to invade living plants to get moisture. They help to play an important role of putting back nutrients to the soil to be used by plants.Full Answer >
