Jumping spiders are included here separately, because, well, because I felt like it.  I estimate there are about 80 or 90 jumping spiders in Arkansas (see the list) in 34 different genera. Phidippus being the largest group in Arkansas (and in most places in the south for that matter). Phids are recognizable by their fairly consistent abdominal patterns (which can be confusingly alike) and their foreleg brushes and their sometimes gleaming, iridescent chelicerae (fang sheaths). The rest of the genera are diverse, from ant mimics to beetle mimics to gaudy elongate creatures. Also note that jumpers can be very different in appearance as they advance through multiple skin molts to reach their adult size and color. Many of the available photos out there depict only the adult color forms. Beware.

The jumpers are difficult photo subjects because they are fast and wary with those spring-loaded legs and four forward facing eyes. They appear sometimes to have a strange higher intelligence. The fearless things also love to leap onto the camera lens  when it gets close and they often appear to make threatening gestures at their own lens reflections. I sometimes have to take them into captivity for a short while to try and shoot them. It is rarely easy. Many have vanished into my home.

In the wild they stalk their prey like cats, moving one or two microns at a time in a slow focused creep. They will take on prey that is literally twenty times their size and weight. And can leap ten or fifteen times their body length by my poor estimate. You don't have to travel far to find them. Likely there are many in your yard and flower beds, on your ceilings and in your potted plants. One may be watching you now.
