Insects make up more than half of all living things on Earth, comprising over one million species. They outnumber humans 200 million to one: for every human, there are two million insects. This figure does not include non-insect arthropods, such as spiders and scorpions. Over 3,600 species of insects have been found in Big Bend National Park, including a new species of beetle recently discovered in the Chisos Mountains. Observing insects opens a whole new world of dimensions, color, form, activity, and beauty. You'll find insects in flowers, wood, earth, fabric, hair, blood, flesh, water, and dung. You'll find them eating these same things, as well as grain, fungi, microbes, glue, spiders, and each other.
