My book, "Jasper Ridge Ants" (2013) is still available. You may be surprised to know that there are at least a dozen genera of native ants in the Preserve, and at least two invasive ones. One genus, Camponotus (carpenter ant) has at least five species here. The book is not an exhaustive or scientific survey of all ants at Jasper Ridge; rather, it shows some interesting activities of those that caught my eye.
You are welcome to leave comments to improve this work. Some questions:
1. Do you know any of these species? Most ant IDs are to genus level only. Please check my IDs as well for errors. (I understand, detailed ID is difficult from a photo. I may be able to provide other photos taken at the same time, if that would help.)
2. Any other info would be useful. The book is intended for people generally interested in Jasper Ridge and local ecology.
3. Is that a winged ant, captured by a spider in the last image?
