Tameable, Hostile, and Neutral arthropods

Dung beetles spawn in the desert, you can ride them and the ball in front crushes mobs it runs over, they're tamed with cactus. Dragonflies (the prehistoric variety) spawn in jungles and lift you off the ground similar to shulkers so you need to make sure you land in a tree canopy or kill them before it's too late. Butterflies drop wing scales which can be used to increase the speed of your elytra. Scorpions spawn in deserts and act like cave spiders, giving the poison effect. Mosquitos spawn in swamps but can be deterred if you're wearing a full set of armor. Crickets spawn almost everywhere and can be cooked and eaten. Mantises spawn in plains (orchid variant spawns in flower meadows) and can be tamed with crickets. They attack all bugs and act like wolves. Not all of these have to be added, but I'll be happy if one receives any amount of attention!
