It sounds like your garden has a wonderful little ecosystem of its own going on! I would love to have so many beneficial insects, for both my plants and my poultry.
I’ve only seen one black widow this year but I’ve seen MANY fiddlebacks. The only to spiders I kill on sight. When I take down mud dauber nests I use my hands, so I absolutely would have died if a thousand baby spiders came crawling up my arm

Lovely bug finds as well. How is your injured chick doing?
I found this Sphinx moth(?) pupa and a millipede that I need to identify while putting hardware cloth up around my chicken run. I love millipedes, but absolutely can’t stand centipedes!
