My husband found this thing, the nastiest looking thing ever on this planet, this morning (Saturday, Jan. 23, 2016) on our back porch here in Fannett, Texas. Our exact address for GPS purposes is 10933 Gilbert Drive, Beaumont, Texas 77705. NASTY!!

Dear Kathi and Richard,
This is the grub of a Scarab Beetle, but we have never seen one so blue.  We are not certain of the species, but we suspect it belongs to a Rhinoceros Beetle in the subfamily Dynastinae.  Members of this family include some of the largest beetles in the world, including the heaviest North American beetle, the Eastern Hercules Beetle that is found in Texas.  Here is a BugGuide image of the grub of an Eastern Hercules Beetle.  According to BugGuide:  “Larvae live in rotting heartwood of logs and stumps, particularly hardwoods, but sometimes pine.”  We are uncertain why you found this grub on your porch, but if someone was splitting firewood, or if firewood is stored on the back porch, the appearance may be connect to the wood.
