Sotol stalk grub - Thrincopyge alacris
Dona Ana County, New Mexico, USA
December 25, 2005
Size: 30 mm approx.
Found inside dead flower stalk of yucca-family plant called Sotol on lower slopes of Organ Mountains. The stalk showed evidence of woodpecker activity, so I split it open to see what might have attracted the woodpecker(s). There were 20 or 30 good-sized larvae living inside it. I saved the bottom 20 inches or so of the stalk intact to see what might emerge after any larvae inside it pupated. These larvae seem intermediate in form between Buprestidae and Cerambycidae.
