A spider of the family Polytminae. It spins a shelf-like web around garden trees or hedges, and builds a tubular dwelling at the back of the web. It is commonly seen from flatlands to mountainous areas. It is distributed throughout Japan except Okinawa, the Korean peninsula, and China. Body length is 15-17mm. Both the cephalothorax and abdomen have two thick black vertical stripes on a gray background, and the abdominal vertical stripes are separated by several gray horizontal lines. It reaches adulthood in mid- to late August, and lays eggs in mid- to late September in the back of the dwelling or in a birthing chamber made from collected leaves.
