Insects 31 images Created 3 Apr 2012
Roughly half of the lifeforms alive today on earth are insects. As wildly different as they are in appearance, behavior and the habitats where they live, they all have certain things in common: they all have an exoskeleton made of chitin, three pairs of legs, three main body parts (head, thorax and abdomen), compound eyes and one pair of antennae. It is believed that there are over a million species found around the world. That's a lot of bugs!
