Central Mexico Beetle
May 21, 2010
This colorful beetle was observed on some rock steps near hot springs in the Guanajuato province of Mexico. There was lots of vegetation around the area along with springs. At first I thought someone had painted this and put it there for a joke, but on closer look, it started to move and walk away. I have yet been unable to identify this guy.

The immature Giant Mesquite Bug in the genus Thasus in your photo will lose its bright coloration upon incomplete metamorphosis into a winged adult. We are not certain that it is Thasus neocalifornicus, which is found in the American Southwest and Mexico, or Thasus acutangulus, which ranges further south. We profiled the latter species in an earlier letter.
