Jumping Spider vs. Coffee Mug

Kathy and I were enjoying the warm noontime sunshine on our back stoop.

I noticed a little jumping spider approaching my coffee mug.

No doubt this was a new vista for this spider to contemplate.

I wonder how my coffee mug registered in this little fella's world view.

The jumping spider family (Salticidae) contains more than 500 described genera and about 5,000 described species,[2] making it the largest family of spiders with about 13% of all species. Jumping spiders have some of the best vision among invertebrates and use it in courtship, hunting, and navigation. Though they normally move quietly and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats.
