Phidippus johnsoni is one of the more distinguished denizens of our yard, and occasionally house. It is the only creature I have identified to species based on the quality of my spider-averse girlfriend's screams. It's big, its abdomen is I'm-dangerous red, and it has iridescent chelicerae. I thought that was deserving of a poem. (Poetry's not my thing, but then drawing wasn't once either).
