Hi, this is a Long-legged Sac Spider, Cheiracanthium mildei. (They are very common.)

OH MY GOD DON’T KILL IT, IT’S RARE!!

It is a Green Huntsman Spider, also known as Micrommata Virescens. Their species is in decline, possibly due to habitat loss. Green Huntsman spiders have a bright green carapace and legs. The females have a bright green abdomen which has a darker green stripe along the top, bordered in yellow. The males have a yellow abdomen featuring scarlet colored stripes. Both sexes have white circles around their six black eyes.

It happens to all of us. 🙂 Please keep your passion for protecting threatened species and don’t let fear of a mistake hold you back!

May is basically spider month. I can see from the picture you’re shining light on it (because of the shadow). I found one in my shower curtain (just south of Detroit, MI) and when I let up the jar it glew yellow. It was absolutely a Long Legged Sac Spider.
