Defending a diversity of bugs... Relevancy of arthropod biodiversity?

First of all, I recognize my bias -- I LOVE bugs, and I simply love finding so many different kinds of 'bugs' (arthropods in general). They're so tremendously biodiverse, they live anywhere and everywhere, and I think they're genuinely the most interesting organisms on the planet. There is such intrinsic joy when you appreciate bugs.

But, I've also found myself 'defending' my interest in bugs -- specifically, the relevancy of doing biosurveys and documenting lots of bugs at parks. I try to create some good 'talking points' on why bugs matter, but I'd love to hear what others use/say when talking about how important bugs are, and why we should care about bugs. They're not 'game species' like deer or turkey, they're not as big or charismatic as some of the vertebrates -- and heck, sometimes they don't sit still like plants!

Here's my typical message:
Bug diversity means plant diversity.
Bug diversity means bird diversity.
Bug diversity means healthy wildlife habitats.
Healthy wildlife habitats mean more ecosystem services like clean air and clean water.

I also think that bugs are the perfect representatives of the urban ecosystem -- at first glance they may not seem significant, just like a small urban park or a front/back yard may be. But, when you recognize that the urban ecosystem is made up of a mosaic of urban parks, yards, cemeteries, vacant lots, then you notice how important these all are.

Anyways, I'd love to know some of the talking points that you've used when talking about why bugs matter (the relevancy of bugs). :)

Interesting. I ran into someone I had not seen since the Covid days at the feed store in Lexington yesterday. We were both buying bird seed. We talked a long time about all things wildlife And he spent a good deal of time telling me about how important bugs are to the world. Loved it!!!

Well... Sam, now, I don't have a great answer for this and would probably flounder. Especially when the first default so many people have is to scream and squash bugs.

I guess... well, I guess with the right person, say you're looking at a boring old moth, well, I guess you could always show them how the moth is actually quite fashionable and wearing some very beautiful clothes, like a Victorian lamplighter shawl, and how cool is that? Here's one that has a green furry cloak; here's one that is dressed in an orange, purple, and green winter coat - do you think the fuzziness helps it stay warm? Look at this one, surely the extra white curl is like a wig!

Maybe that little bit of anthropomorphizing could be the key to some people's hearts. (Okay, probably younger people. I actually tried it with a relative who was very upset about assassin bug nymphs, which the person thought was milkweed bugs, and I got to talking about the business suits they were wearing with cute little black buttons and bowties and honestly, it did not work, I managed to collect the assassin bugs and carry them off before the yard spray came out. I think... we gotta start with folks who are young and have less preconceived notions about bugs being bad.)

I definitely agree with you, sam. bugs are extremely helpful in mother nature's ecosystems. other animals rely on bugs for a food source, a lot of bugs pollinate plants that other animals (including humans) couldn't survive without, and bugs are also great decomposers, cleaning up the natural wastes. so in my opinion, this paragraph was well written and very well explained, sambiology.
bugs may Appear useless or annoying, but they have a major purpose in Mother Nature.

First, I share your bias. I love bugs! Second, we shouldn't need to justify bugs or any other aspect of nature. Nature just IS, and that should be enough. But for some, I guess, it isn't.

As already mentioned, there is the "beauty" argument. It's not just moths and butterflies that are beautiful to the eye. There are some gorgeous beetles, odonates, true bugs, mantids, and others. We also have to remember that the beauty that we see did not evolve for us but for some function in the insect's life cycle.
Then there's the pollinator argument. Without pollinators, which occur in so many groups of insects, not just bees. Except for the grains, essentially all of our fruits and vegetables rely on insect pollinators to reproduce. Interestingly, we in North America have become almost entirely dependent upon a single introduced species, the Western Honey Bee, for our agricultural pollination, a strategy that has become questionable with the significant declines in honey bee populations.
There is the "sanitation" argument, as mentioned by @nature-tracker. Without insects, we would literally be up to our eyeballs in s***. Think Australia after the introduction of cattle and before the introduction of dung beetles.
Most importantly, however, is the importance of insects in every food web. When "justifying" bugs to "non-believers," you may have to defend those insects that truly "bug" us, like mosquitoes. As annoying as they are to us, we have to remember that nature does not evolve to serve humans, and mosquitoes have an important role in aquatic ecosystems. Without mosquito larvae, those bass fishers love to catch probably wouldn't be around, either.

I have a front yard pollinator garden with hundreds of arthropods including butterflies, bees, wasps, beetles, grasshoppers, spiders, ladybugs, aphids, spittlebugs, and so much more. Two houses away in both directions, and there’s almost nothing – sometimes non-native honeybees feeding on non-native vitex, non-native fire ants, and wasps hunting for caterpillars in their trees but they’re treated as a pest. Yesterday I had a lawn guy come by my house to see if I wanted to get my yard sprayed for insects since he’s working in the neighborhood. The problem is, people try to make human living spaces including our lawns as completely apart from nature and try to sterilize the environment around our homes.

In reality, a diverse environment is a sign of a healthy ecosystem. Insects are the primary consumers and the lowest consumer trophic level on food webs. Without enough insects, there would be fewer birds, mammals, reptiles, and even plants that rely on them for pollination – including most of our produce! Many insects are also a keystone species,

Of course you know all of this – the challenge is trying to convey these concepts to people who grow up being taught to fear arthropods.

I thought about this a little more from a practical angle today after finding a dying owlfly in a bowl of water left out overnight. (It's not my water bowl, but I suspect most people would see it, say "oh, ick" and dump it out without thinking about it much more).

While I really do believe that my silly anthropomorphizing of little creatures that may otherwise be seen as drab or scary can be helpful with the right audience - to make them more 'fun' and relatable - in truth I know I can't expect to pull that out of my hat out with most adults.

Perhaps when we look at "bugs" from such a wide lens it is hard to share the importance of them. We are trying to carry too much weight on broad concepts that may not be so meaningful to somebody no matter how we phrase those concepts. Maybe we need to narrow the focus so that a person can understand the value of one or two things at a time.

I've had some success getting people to see paper wasps differently when I talk about how they keep pest caterpillars out of my garden. I pull up some of the pictures I've taken of them in action, grabbing caterpillars from my leafy greens. I talk about how the queen pollinated my early flowers. I stand by their nests to show they aren't interested in attacking me if I'm just hanging around.

Via another analogy - Sam, I went on a nature walk you did last year at Native Plants and Prairies Day. I don't remember everything but the background history you gave on the Arkansas yucca has stuck with me; I imagine it stuck with a few people, who now might see a space and think of that plant and see the value of the space differently. The people who held pieces of the plant could imagine making ropes or baskets with it. What you did not do was tell the group about the plant's value to the ecosystem scientifically, or speak about it in broad ecological terms - it was story showing the plant's relevance in our society. Bugs -- one at a time, perhaps.

Great question! Much of my teaching about nature has been with kids, so this is somewhat simplistic—but maybe that is an okay approach for adults who say they ‘hate bugs’? What's in it for me? How does that bug fit into my world? I may not love that creepy caterpillar, but I appreciate that it could serve as food for the birds that I love to watch outside my window. Or I don’t like that a bee could sting me, but I appreciate that they pollinate the flowers that I love to look at in my garden. It's simple, but it can get smaller brains thinking in a different way.

So true.

I think of them as indicator organisms. Are these insects normally here? No. Why are they here now? We better find out because climate change, trees disappearing, or insert reason here. Same for insects that go missing. In fact, I haven't seen a single dogbane leaf beetle all year at Twelve Hills, and they're my absolute favorite. Where are they and why didn't I see them this year?

Plus, they're just neat to look at up close. Even the plain little brown ones. Get a macro lens and suddenly you see their cool patterns and textures.

This is something I grapple with a lot - not justifying my love for bugs, exactly, but dealing with the burden of living in a world where bugs are so eagerly despised. Knowing that in most cases, it's not even on an individual scale - it's a reflection of the bigger picture, a society where there's profit in teaching people to fear and to kill our native wildlife. Sometimes it feels hopeless when I look up an interesting bug or a rodent to learn more about it and the first ten search results are pest control companies telling you what poisons to buy to kill them. Most recently, it was springtails - the article said that although they cause no damage to people or property, they're a pest "due to their large numbers". Why does simply existing near people make them a problem? They're eating the mold growing in basements and in between walls; they're doing us a service! And people will thoughtlessly pay someone money to get rid of them. Sometimes, it seems hopeless to even bother to change peoples' minds.

But we wouldn't be who we are if we gave up the good fight - I think bugs are a good teacher, in that regard. They're eaten by everything, one wrong step away from being crushed or splattered onto a windshield, but still they keep going. You can pluck a leg off a bug and it might not even notice. I owe it to nature to be bug-like in that way; to do whatever I can to share the gifts nature has given me with others. If my enthusiasm rubs off on even one person, who knows what kind of a difference that could make?

I wish the answer to your question was as simple as "You should respect life in all its forms, not just when it's convenient for you." That's the real answer to the question, but it's not the answer that's going to change the mind of someone who doesn't already understand that.

I think you may be more equipped than I am to give the answers that might actually sway people, and the common ones have all already been said (food for other animals, pollinating our crops, decomposing our waste), but here's a few more for the arsenal:

-Removing arthropods from the food web would simply cause it to collapse; if you work your way down, pretty much everything relies on them. And even the large herbivores need them pollinate the plants they're eating.

-They're food for us, too. Lots of cultures traditionally eat insects; even in Western culture, we use shellac and carmine. And if that still doesn't do it: what about the chickens that they eat? Insect protein is a great chicken feed. Related to that, it's likely that early humans were able to grow our giant brains by eating bugs. Eventually, that expanded to include hunting bigger and bigger animals - but insects were probably the first protein-rich foods that allowed us to become the weird apes we are today.

-Silk and honey! Without insects, we wouldn't have honey in our tea or silken pajamas. The silk moths in captivity are completely domesticated - they can't survive without humans, we're intrinsically linked. Honeybees could choose to leave their hives, but the protection offered by the humans who tend to them is worth losing some of their honey.

Sorry I waxed poetic about this, I just have a lot of feelings about the value of bugs and nature in general.

Thanks everyone for the feedback on this! I really do appreciate how others highlight just how important (and awesome) bugs are.

Anytime! My favorite part of inaturalist is that we all can pitch in to friendly and honest discussions about our natural world.

Publicado por nature-tracker hace 24 días

And this is just about terrestrial arthropods! There are so many different species of aquatic arthropods too!

Shrimp, crawfish, crabs, and lobsters are basically water bugs. 🦐 🪳
