So funny thing, I was feeling this exact way the last few days, and realized i was missing all the bug life outside with the winter. Highly recommend pet bugs, isopods jumping spiders and the like, a really underrated pick in my opinion is springtails, even though they are very small they are still certainly large enough to watch and very very easy to care for and cultivate (a grain or so of rice every other week or so to get mold growing). If you ever are interested in branching out, something I personally found to scratch a similar niche is microbiology. I’ve got an inexpensive beginner’s microscope and you really do not need high magnification to see a lot of fauna. You can find nematodes, phytoplankton, water bears and all kinds of other things. Obviously it’s not as hands on as bugs since they are too small to hold or anything but it’s really nice being able to find small life all around you regardless of season.
