Modern time is often referred to as the "Age of the Insect." At any given time, one billion billion insects are alive on our planet. That many of anything is nearly impossible to imagine. Insect fossil records go back 400 million years, which means they even survived the great extinction at the end of the Paleozoic era. Renowned biologist and author E.O. Wilson equates this to being equivalent to surviving a total nuclear war. But what is it about insects that allow them to persevere when other organisms come and go with relative frequency?
