Little brown male jumping spider
This little brown jumping spider was on our windowsill on August 16, 2014.
He was only about 3 mm long, so not very big at all. I can tell he’s a male from the big, boxing-glove-like pedipalps on either side of his face.
He has good, general-purpose camouflage that is excellent for inside of a house, hanging out on the woodwork or running around in the dust under furniture.
Looking through the possible candidates, I think it is pretty likely that he is Sitticus fasciger, a species of jumping spider that has cheerfully adopted the human house environment. So, aside from looking identical, the fact that we found it in the house goes nicely with this ID. They originated in northern and western Eurasia, but were found to have come to North America by the 1950s. They apparently like to hang around lights at night, preying on the small insects that the lights draw in. This is quite likely the same species as the first jumping spider I ever photographed, way back in 2007 (but that one was evidently a female).
