Mac Not Able to Read SD Card

I have a microSD that I use in my raspberry pi. I have it plugged into my mac through an adapter and am trying to use it. However I caot erase any of its contents and it (contents) does not show up on the computer.

The only place I can find it is in disk utility. I am able to erase it and perform first aid but I can only see it show up in Disk Utility, not in finder.
