Why do many people seem to believe that other animals have none of the advantages of a human and yet all of the drawbacks? As in, not capable of moral thought, but fully capable of suffering? You're right, most animals don't have the capability to think like that.Why do most people seem to not acknowledge that this is because humans have the capability to do this while other species do not?
Humans also have the capacity for evidenced abstract thought, so we can look into the question of whether bugs can suffer and come up with a solid answer.
You said a few times in this thread that bugs can feel pain and suffer. Evidence indicates that this is incorrect.

-Pain is a result of nerves sending signals to the brain, which then emotionally processes it as pain. Raw nerves themselves enough are not enough to experience actual pain and suffering, any more than little electronic input and output sensors of a robot can feel pain and suffer. As an example, take a look at those Buddhist monks that can burn themselves alive out of protest while sitting in perfect serenity, because their meditation is advanced enough to detach their emotions from the raw signals of the damaged flesh. Bugs have nerves but do not have the structures necessary to turn pain into an emotion. Many bugs can live for days without a head, because the brain is a small component of their overall nervous system and doesn't actually do all that much.
-Animals that can suffer, learn from their suffering. That's part of the point of suffering: nature doesn't generally evolve species with completely unnecessary capabilities, because they come at a cost as well as a gain. That's why there's no reason for a tree to suffer; it can't do anything about it anyway. A human learns not to touch a stove if she was burned by a stove. If a dog is mistreated, it will make clear signs of being afraid of the one that mistreated her. But bugs are so simple, their strategies for life don't rely on learning in most cases. If it a bug gets hurt at something, it doesn't show signs of avoiding it in the future. Its ability to feel stimulus seems isolated to dealing with things in the present moment, such as fighting, hunting, fleeing, etc.
-Animals that can suffer change their behavior when they suffer. If a human is in agony, she or he doesn't do things like eat and have sex and act normally. Same thing with a dog or a rabbit- if it's cut open or some other severe wound, it does nothing other than fret about that injury. Bugs don't do that. A bug with a crushed abdomen will still do things like eat or try to mate, and generally acts like nothing has happened. In science class once, we had two praying manti in a tank, and they began having sex, and before the male was done, the female began consuming him while he was still inside of her (they do that sometimes, his sacrifice is a meal for the soon-to-be-mother) by biting off his head in small chunks, and he fought a bit and then just kind of went with it, and continued having sex without a head. That's what bugs do- they'll struggle and fight when there is a threatening stimulus but when they are no longer scurrying around for survival and the threat is gone, regardless of the extent of their injuries, they'll appear clueless to them. Bugs survive by numbers, not individual quality. Like, when a spider egg sac hatches and countless spiderlings spill out, 99% of them will die shortly. A fraction will live. In the wild, bugs generally don't die well- they get consumed from the inside out by parasites (and act normally), they get eaten by predators, they get picked apart slowly by other bugs, they get partially crushed and left to die in various ways, etc. And there's no indication that they suffer at all, or to any bothersome degree.
So in this thread, it's been said that humans are anthropocentric for, say, not caring too much about the well-being of an ant. Yet, posts that are suggesting without evidence that bugs can suffer and feel pain like a human, appear to be anthropomorphic- giving human characteristics to non-humans.
Imo, how to behave with regard to things should be informed by evidence of the characteristics of those things. This is why, as I said earlier, I care more for a human than a cat, more for a cat than an ant, and more for an ant than a bacterium. We have good evidence on how they respond to things, what they've evolved to need to survive, and how they respond to pain and how they seem to experience it.
This is why, if termites are found to be eating a house, the correct approach is to get rid of the termites.
