I'm not an exclusive bird observer. I make observations of 'moving' organisms from mammals to invertebrates, recording my observations on iNaturalist [1], which is a pretty good way for me to track what I've seen.
I'm always surprised by the quality of insect pictures on inaturalist. What are you using?
My focus has been on fungi and plants, but I try to scan what people are recording in my region just to keep up with what is around, where it is and what time of life it is. The turtles laying eggs around now are worth keeping an eye out for as an example.
I am currently using a Sony RX10M4 camera with a Nisi close-up lens attachment.
It is a 'point and shoot' model (no detachable lens), so the lens attachment helps to zoom in on small organisms. With some support, I can take handheld shots of insects about 5 mm in length.
At the moment, I still find mirrorless cameras by Canon, Sony, etc. a bit too expensive for my taste, so I compromised by getting the RX10M4, which is considered one of the best P&S cameras with a huge zoom range, which is good for shooting all kinds of wildlife, big and small.
