Is there a particular bug or fish that your villagers always ask for?

When my villagers have thought bubbles, oftentimes it's because they want a certain bug or fish, and for me they keep asking for wharf roaches, so I've taken it upon myself to catch a stash of them in advance whenever I see them, so when a villager asks for a wharf roach I can just whip out my shed and grab one

What about you guys?
