Each spring vacation, San Jose State University offers a course, "Field Studies in Natural History": a trip to Death Valley, studying geology, ecology, plants, insects, animals etc. Even a visit to the Timbusha Shoshone Tribe. In addition to undergraduates taking the course for credit, they welcome some others to come along. They have offered this for 80 years. I finally went along. Here are some insects, spiders, a mite, and more. Many different species of ant.
To save time, I have not identified the plants or insects. Please leave a comment if you know the ID! I *have* tried to identify the location and time of the photo, to help you link it to the ecology.
I do have many other photos from this trip. I hope to sort, process, and post them some day. Don't hold your breath -- I seem to be busy these days.
