Well, I love catching and looking at shrimps and crabs at the beach.

Dragonflies look quite cool to me in general, especially when they have that green or blue kind of metallic shine. They devour mosquito larvae too, as a bonus. I live in a fairly wet area so I see dragonflies frequently, waterbugs too (if you mean stuff like nepa).

Spiders don't bother me. Truth be told, where I live the biggest spiders must be tegenariae, they're harmless and just run into hiding as soon as they percieve a threat. I think some spider species look cool, like the goofier looking jumping spiders, but I've not seen them in the wild, even though I believe there should be some where I live. They're pretty tiny though.

Spiders are cute because they like to play fetch if you throw a bug in their web
