This is a repost from November 28, 2014, but it still applies today; and not just for the American holiday of Thanksgiving, but for every day in every location on the globe. Life as we know it would not be possible without insects and their kin.
A couple days ago the following post crossed my Facebook newsfeed, and it is an excellent reminder of why insects and other arthropods are so important to us as human beings, and to the planet Earth as well.
"Thanksgiving is tomorrow …and we all have much to be thankful for. But don’t forget to thank our pollinating friends (bees, beetles and a host of other critters) that provide 1 out of every 3 mouthfuls of food and drink we consume. Without them, and the invaluable service they provide, our lives and our world would be drastically different. Happy Thanksgiving!"
Beyond pollination, insects and related invertebrates furnish many other "ecosystem services" that we can't easily put an economic price on. They are responsible for seed dispersal in many plants. They are at the front lines in the decomposition process for all organic matter be it animal or vegetable. Their activities aerate and mix the soil. They serve as the basis of the food chain, feeding other invertebrates and many vertebrates from fish to birds to bats to aardvarks and anteaters.
A scientific article was published in 2006 in the journal Bioscience that attempted to quantify just four of these ecosystem services: pollination, pest control in croplands, waste (dung) removal on rangeland, and food for wildlife (recreational hunting, fishing, birdwatching, etc). The carefully calculated estimate of the value insects thus provide, in the United States alone, was a staggering sixty billion dollars ($60,000,000,000).
Insects are quickly becoming "watchable wildlife" in their own right. Countless field guides and online resources cater to those who enjoy observing butterflies, dragonflies, moths, tiger beetles, and nocturnal "singing insects" like katydids and crickets. What will the next craze be? It is clear that these communal passions are not only sustaining themselves, but actually growing in popularity, as witnessed by the explosion of National Moth Week, for example. There are festivals for everything from butterflies to bees, even mosquitoes (in Paisley, Oregon).
Insects and other arthropods are also used extensively in scientific research and medicine. We owe much of our knowledge of genetics to research conducted on "fruit flies" (Drosophila spp.) and flour beetles (Tribolium spp.). Fly larvae are used to clean wounds because they carefully avoid living tissue while secreting fluids with antibiotic properties. Many patients with joint inflammation and diseases swear by "bee venom therapy," even though it may be relegated to the category of alternative medicine by the healthcare establishment. Spider, scorpion, and insect venoms continue to yield promising derivative compounds. Some fireflies produce chemicals that show promise in fighting herpes.
Many people find inspiration in the world of insects. We owe the invention of paper to ancient peoples in Asia who observed paper wasps constructing their nests of chewed wood and plant fibers. We continue to refine the performance of our aircraft thanks to experiments on, and observation of, insect flight. Insects are being enlisted in the fight against terrorism because of their acute chemo-tactile senses that far exceed our own abilities to detect harmful substances and agents; and their small size that allows them access to the most remote cracks, crevices, and other cavities. Artists are endlessly inspired by the beauty, colors, and patterns of insects.
Personally, I value insects and arachnids as an endless source of fascination. Their physical diversity is mind-boggling. The behaviors they engage in are amazing. You can find them anywhere and everywhere, even inside your own home in the middle of a cold winter. Their stories demand telling, and I feel honored and privileged to have a modicum of ability to bring them to life for others.
What is it about "bugs" that you are thankful for? I encourage you to share your thoughts and feelings here.

I am thankful for bugs because I think they are the most exotic creatures on Earth, ALL have a purpose & provide hours of amazement just observing & marveling at their behavior. You don't have to go in search of them, they are always there. They could survive perfectly well on Earth without humans to interfere.
ReplyDeleteBugs and plants do really make the world go round. Your passion is evident throughout this post for bugs. Thanks for sharing the wonder that they bring to the world.
