Found and collected unknown eggs on Sept. 17, 2015 from a cluster that was deposited on the outer stucco wall of a rest area in southern New Mexico. At that time, I set out to try to identify them, and found a picture of the same kind of eggs, also unidentified. (pls click thumbnail)
Eggs were about the size of those tiny Indian "seed beads".
They hatched today! They seem huge for caterpillar hatchlings, bigger than, say, a tomato hornworm hatchling, and you know how big those guys get!
