Common at this time of the year, Tenuiphantes zebra is one of the first spiders to emerge in this area each spring. Though very small, their dark bodies are easily visible against the white background of the snow upon which they spend a great deal of their time. Many of them make small sheet webs within tiny cavities in the snow, in which they hang upside down and catch springtails and other small arthropods. Both males and females make these webs, but individuals of both sexes are more usually found wandering on the snow. They can be active even when the ambient temperature is barely above freezing. This lone adult male was probably searching for a female, on a sunny day when the temperature was around 9C. ID was based on similarity to T. zebra identified via palps from this location in March, 2009.
