The Railroad Down Under

by Eric Neubauer

I saw many things during my expedition around the lower half of the Texas Panhandle. Too many in fact to even summarize. So here is one thing I particularly noticed. I spent some time at Big Spring State Park after sunset.

The land was dry, and the spiders were scarce. Finally, I found a nice adult female Big-eyed Wolf Spider at the edge of the road near the entrance. This is only one of a growing number of fairly large
unnamed wolf spiders in the pipeline.

While preparing photos for iNaturalist, I was struck (not for the first time) by the rainbow colors on the chelicerae of this species. The chelicerae are analogous to human lips or jaws except for housing venomous spines at the ends and separating in a vertical plane. Wolf spiders often have bold or complex patterns, but here is something extremely delicate.

Starting earlier this year I added face shots to my routine. After all, this is what spiders see when they meet each other. In this case it captures a colorful detail that would have been missed and shows how big the eyes of the Big-eyed Wolf Spider really are. The white circles in six of the eyes are artifacts, reflections of the dedicated light ring that is part of my setup.
