Great Lakes region, USA. May 2026.

I was birding again and stumbled upon this little jumper on a developing acorn. I swapped to my macro for the close ups, but my telephoto did pretty well for those zoomed out shots. "Eris" is the Greek goddess of discord and strife. "Militaris" is Latin for "of a soldier" or "military", so this spider's name is "discord of a soldier" which is pretty badass imo. This spider wasn't too interested in the many tiny beetles that walked right up to it. I was hoping I could get some action shots, but alas.
