Spider & Egg sack that's fluorescent in sunlight green. In Jefferson, OH and wanted to kill it, however I didn't when I saw it change color when sun light hit it. When clouds cover sun, it goes back to brown including egg sacks. Tried to ID, comes up as common house spider. House spiders don't turn colors. Didn't have my black light with me, spider in the barn. But this reacted the same way a mineral does under black light. Only in reverse. Color activated on spider and eggs when sun is direct. Indirect light, goes back to brown? Help me identify. Thank you Tina Pope Spider & Egg sack that's fluorescent in sunlight green.
