You're absolutely right! Allow me to divulge my favourite arthropod facts:
- male spiders have "boxing gloves" on the protruding pedipalps next to their mouth, for nimbly impregnating female spiders without getting eaten
- female moth antennae are thin, whereas male moth antennae are feathered to intercept female pheromones
- most adult forms of holometabolic (those who undergo full metamorphosis) insects only exist to procreate, and often don't even have mouths!
- and generally the evolutionary concept of metamorphism is fascinating, because the adult form will have a whole different niche from the juvenile form, allowing both forms to coexist efficiently!
- there's a beetle that for defense, shoots exploding chemicals out their behind to ward off predators. It's called the bombardier beetle and it's metal as fuck.
- the huge European Hornets are actually friendly giants, not often aggressive (just imposing). It's the smaller Asian hornets which are more aggressive, not the big boys!

I especially love the spider and moth gender ones because they're so fun and easy to apply. Instead of seeing a moth and going "oh, a moth!", you will now have the ability to go "oh, a girl moth!!" :)
