I found this bug on my front porch in San Antonio, Tx on Sunday Nov. 7th. I have was wondering what it is.
Thanks in advance
There are two genuses of beetles with the common name Ironclad Beetle, and your specimen of Zopherus nodulosus haldemani is one of them. We have another letter and photos from June 2004 on our Beetles 2004 page with additional information.
