Hurrah! Hurrah! March is here and spring is springing up which means the return of many insects. Insects are the most diverse group of animals with more than a million described species and they represent more than half of all known living organisms. There are even estimates of 5.5 million insect species with about 1.5 million beetle species. And insects are found everywhere! From oceans to deserts, from the arctic to the equator. Insects come in all shapes, colors, and sizes. From the large elephant beetle to the tiny fairy wasp, from the colorful coreid bug nymphs to the black beetle. Some have wings and fly, others spend most of their life in the water. Learn more about insects and entomology, the study of insects, through the books and resources below.
