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.Continue Reading
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
Centipedes feed mainly on small animals and insects. Some centipede species are scavengers and feed on whatever decaying plant or animal material they can find. Giant centipedes in South America have been known to eat larger creatures, such as frogs, mice and snakes. Centipedes in homes tend to feed on insects, as well as cockroach egg cases. For this reason, some homeowners choose not to harm centipedes.Full Answer >
All insects have six legs that are mainly used for walking, but they are also useful for jumping, hunting, swimming or digging burrows. All adult insects have three body parts: the head, the thorax and the abdomen. Insects also have a pair of antennae and two pairs of wings.Full Answer >
Praying mantis species are carnivorous and primarily feed on other insects, such as butterflies, moths, grasshoppers and crickets. However, adult mantids aren't picky and eat rodents, birds, reptiles, frogs and much more as well.Full Answer >
Thorough elimination of lice infestations is often difficult due to the insects' increased natural resistance to over-the-counter treatments and the frequency with which they reappear following treatment. Methods that work on adult lice are often ineffective against nits, while treatments for nits may not work with adults. The likelihood of success against lice outbreaks increases the more methods one uses, which may encompass over-the-counter, prescription and home remedies.Full Answer >
