For those wondering, I do sometimes place my favorite sand grains into the empty molted head cap of small jumping spiders. It’s an obsession, really. I’ve done about 30 of these total. This is a favorite as I love the green color of that one grain. 3mm field of view. I love Bandon Sand!

I’m 44, obsessed with sand and jumping spiders, size 14US and love avocados.
