If there's one group of organisms on this planet that seem to really embody the core tenets of life to such an efficient extreme, it would be arthropods. They are incredible. They're also some of the few animals that are this easy to observe up close for such an extended period of time WITHOUT THEM CHANGING THEIR BEHAVIOR DUE TO YOUR PRESENCE. Super rare for a non-professional observer!
Anyway I adore moths and rolypolies the most as those visit me in my room most often. I always escort them out after watching a bit. Other close-by friends would be silverfish, though I've only spot a single one so far, flies and mosquitos. Mosquitos are the only ones I usually end up killing, it sucks but they're really hard to get to leave when they'd rather just eat you. May figure something out for them one day.
Flies are a bit like a puzzle of herding getting them to go through a window instead of against the glass. Still, flies are fun to watch, they groom a lot (legs, wings and eyes) and just look for things to graze haha.
I'll also get a "leaf footed bug" occasionally. They startle me because of the uncommon sighting and size. They're slow and methodical until you agitate them and that startles me again. Usually requires a glass to capture and escort. They're still a good memory because it was one of the first times I bothered visually identifying a bug using an insect guide, though I did it out of concern that it would attack or something.
Last but far from least. Sometimes a panicked wasp will shoot into my room, a classic yellowjacket. Now outside, I don't mind wasps, they're a bit unnerving but I've spent enough time near them while they chew wood to come to appreciate them with caution. But when they're in my room I keep my respectable distance. As in, when they're in my room, I won't be. I wait patiently for them to leave the same way they came, which happens fast enough. There's nothing for them here. They look beautifully terrifying.
And yes I used arthropods instead of insects at the start for the sole purpose of including roly polies. They are the bestest boys. We can only strive to be more like them.
