I think its a Mica Cap but I am peeping a very cute isopod as well.
Mycology
This slug was finishing it's meal as i started clicking.
Speaking of isopods I'm getting ready to evict 100's from my terrarium to the compost, they keep eating my moss.
If you are on iNat there is a neat project called Molluscan Mycophagy where you upload observations of slugs and snails eating mushrooms. You upload an observation for each organism and use fields to indicate the "eating/eaten by" interaction.
I lucked out with my sandstone pods, I have plants and moss and they don't touch them.
I've been using Plantnet to scan everything in my yard but I'll check out iNaturalist.
I've even tried feeding the pods potatoes buy they still cleaned out all but one kind of moss and every little seeding that pops up. It my fault by not cleaning and quarantining my yard finds but my granddaughters do love the "rolly pollies"
