Grey Wall Jumper Menemerus bivittatus Spider  
Every so often I notice these little spiders, most often on a building. They usually run away while I approach, but this time I managed to slip my hand in the spiders path and briefly block it's escape. It's spider is small enough to sit on my fingertip.

The next time you want to get rid of a spider on your home or office, remember these little grey wall jumpers. They're small, they're afraid of people, and they're great little guards who catch and consume other less welcome bugs that might try to come through that door or window instead of just living near it.

It's a shy Menemerus bivittatus spider (I think.) I've found that the best time to take their picture is when they're eating.

See the dead moth in the palm of my hand?  It's an odd angle, but I wanted to show the un-cropped photo to illustrate how very small the little brown moth is.
The spider got upset when I got too close while taking pictures of it enjoying its meal, and it dropped the moth.

 They seem particularly fond of flies and small bugs like this unfortunate moth.

The metallic green bug that the spider is eating is a long-legged fly. Here's another fly:

I've been able to photograph the female Menemerus bivittatus quite a few times, but the males have hidden somewhat quicker. Here's a male trying to duck out of sight:

The male was on the same window as the spider eating the green fly; they seemed to be a couple.
