For every single human being on Earth, there are 200 million insects. Both in terms of species and sheer numbers, insects outnumber all other animals on the planet. More than a million different species of insects have been described and named, and thousands more are discovered each year … some estimates exceed 30 million total in existence.
Over 70 percent of all known animal species are insects and almost half of them are in the beetle category. Among the more infamous are boll weevils, which crossed into the United States from Mexico in 1892. They proceeded to destroy great swaths of the cotton grown in the South. Even today, efforts to eradicate them in both countries is problematic.
Thanks to the amazing adaptation skills of insects, they flourish in every land habitat and play a key role in the global ecosystem, recycling dead plants and animals, pollinating flowering plants, and providing food for a host of animals. In fact, insects are so vital to life on Earth, we could not survive without them.
Insects are also the most numerous of the arthropods – animals with tough external skeletons and jointed legs.
A remarkable example of biodiversity is the beautiful Monarch butterfly, which starts life as a wingless caterpillar that spends most of its time eating. Its metamorphosis into a butterfly is one of the most dramatic changes in nature. Within two hours of emerging, the butterfly is ready for flight and launches into the air to start looking for a mate so it can breed and create a new generation.
Monarch butterflies spend the winter asleep in the warm woods of Mexico and California. In spring, they awake and fly north to find milkweed plants that do not grow in the warmer southwest. Then, they lay their eggs and die. The next generation then flies further north and does the same thing. After two generations, they reach the Canadian border. Then, the fourth generation migrates all the way back south again, clear across the United States.
It’s not clear if they seek approval from the Department of Homeland Security or simply rely on special TSA exemptions for frequent flyers. Hopefully, they make it safely, since our fortunes seem to be linked in some mysterious way.
