I found this female wolf spider wandering outside, in the early morning after an
all night lan party. She was carrying her egg sac with her, attached to
her abdomen. When the spiderlings hatch, they will crawl onto the mother's
back, where they will continue to develop.
Wolf spiders are fast ground hunters. They are so named because they chase down
their prey -- not relying on a web for prey capture. For living quarters,
they often use the tunnels abandoned by other invertebrates, such as cicadas.
This saves the wolf from doing any extra work.
Since wolf's are fast, I had to put this one into a studio environment to get a
good photo. I threw a green material over the kitchen table, setup a
strong desk light, and used the Nikon 995 with SB-29 macro flash to get the best
shots. She was very cooperative, and let me take all the shots I wanted.
Once I finished shooting, I took her outside, and released her.
