I just wanted to let you know that the beetle on your page 2, Some one gave the correct on the family name, but didn’t give a name on what they are called. I live in Tucson Az. & to my knowledge are mainly known here in the SW
They are called “Palo Verde” beetles, because the female will lay their eggs in soil surrounding the Palo Verde trees, which will hatch & live underground for 3 years, feeding on the roots of the trees. They are usually seen in the summer & fly in the early evenings, they are attracted to light, which is why we always find them by our front porch where the light had been on! I couldn’t find anything on your page under that name, so I hope you find this helpful. They are the biggest bug I’ll ever want to see with pinchers! I’ve enclosed a couple pictures.Thanks,
Since that time, we have received numerous other images of the Palo Verde Root Borer that are properly identified. We will include your correction with that long ago entry as an update as well as posting your wonderful images on our homepage and our most recent beetle page.
