Insects are arthropods and represent 90% of all life forms on earth. There are over 1 million different known species of bugs in the world, and some entomologists estimate that there might be as many as 10 million! All of these species are divided up into 32 orders, and the largest group are beetles. They have 125 different families and around 500,000 different species. In fact, one out of every four animals on earth is a beetle!
Insects have three body parts: the head, thorax and abdomen. They have six jointed legs and two antennae. Insects have an exoskeleton which contains sense organs for sensing light, sound, temperature, wind, pressure and smell. Insects usually go through 4 separate life stages: egg, larvae or nymph, pupae and adult. Insects are cold blooded and do not have lungs, but many insects can fly and most have compound eyes.
Insects are incredibly adaptable creatures and have evolved to live successfully in most environments on earth, including deserts and even the Antarctic. The only place where insects are not commonly found is in the oceans.
Insects can be useful in producing honey, wax, silk and other products. They also pollinate flowers and crops. However, they can also destroy crops, carry disease, and be a major pest to people and animals! Spend a little time with us and check out all the cool bug stuff we have.
