Identification

Asian wall jumping spider is a small exotic spider from Asia. It is native to Korea, Japan, China, Mongolia, and Russia. It was introduced into North America in the 1950s and has expanded its range rapidly with the unwitting help of humans. It is now widespread east of the Rocky Mountains. It is common in the south half of Minnesota.

The female body is to 3 16 (4 to 5.5 mm) long, not including the legs. The male is slightly smaller, to 3 16 (3.5 to 4.5 mm) long.

On the male, the plate covering the cephalothorax (carapace) is wide and rounded on the sides. It is dark brown to almost black but is densely covered with white and brown hairs. White hairs form a distinct longitudinal line in the middle. There are four pairs of eyes arranged in what appears to be three rows occupying a little less than half of the length of the carapace. The first row of four eyes, consisting of the anterior median eyes (AMEs) and anterior lateral eyes (ALEs), is curved backward. The AMEs are the middle and forward-most pair of these. They are by far the largest of all of the eyes and can be moved. The AMEs are about twice as large as the ALEs. The second row of two eyes are the posterior median eyes (PMEs). They are very small and are barely or not at all noticeable on most photos. The third row of eyes is the posterior lateral eyes (PLEs). The PLEs are set far back on the head and are almost exactly as far apart as the ALEs. There is a row of erect, stiff, black bristles behind the anterior eyes (AMEs and ALEs) and more scattered bristles across the cephalothorax.

The abdomen is brown and is densely covered with dark brown hairs and white hairs that lie loosely. There are two dark bands with white spots on the front (anterior) half and a pair of large white spots on the rear (posterior) half.

The legs are short and yellowish with dark rings and black bristles.

The female is similar but has a broader abdomen and is light brown with yellowish markings.

This is a cute little jumping spider that was hand held the whole time of filming. It's a male Sitticus fasciger spider and is just as fascinating and curious as any jumping spider can be! Loved watching it clean and taste it's feet with its pedipalps and mouth, and then stomp each cleaned foot several times, as if to say, "there, that one's done!" And like any jumping spider, even tiny ones, they love to jump. This was a fun one to film, enjoy!
