Right now, it's raising bugs. And I don't mean the hobbyist way of buying cool bugs from a pet store and raising them in some plastic container. It's the half-assed way of getting grabbing random bugs I see from my yard and raising them in those plastic soup containers and plastic food trays. I've raised mosquitos (I found mosquito eggs one day, dumped the eggs in some empty peanuts container, and watched the magic happen), midge flies, a whole bunch of different moths, some sawfly, and a bunch of hover flies. I found a parasitized caterpillar and watched the wasps emerge from their cocoons (along with a bonus fly that appeared out of nowhere).

It's just fascinating to me as someone with no zoologist background. There's so many time where I go "well, I didn't expect that." Stuff like how some caterpillars are cannibals or how there's apparently a type of maggot that will tunnel into a moth pupa, feast upon the pupa from within, pupate within the now empty moth pupa, and emerge from the two pupas as a generic-looking fly. And it's not like a parasitoid fly since all the parasitoid flies I've searched for online were smaller than the caterpillar when this fly is just a generic fly. I remembered being so confused when the sawfly emerged because sawfly larva look and act like caterpillars. I expected a moth and got some wasplike insect instead.

If you don't want to be weird like me, there's always gardening. You'll encounter the bugs that way as well.
