These Black Carpenter Ants are big. The biggest are around 0.5in/1cm in length. They were observed in the Great Trinity Forest and were busy feeding on this weird yellow goo when I found them. I have no idea what this sticky-looking stuff is, but it was attracting flies and pillbugs too. If anyone has a suggestion as to what this goop might be, please leave it in the comment section below.

UPDATE – August 3, 2020

This substance has been identified as River Otter “anal jelly” as described in an article from the Smithsonian Magazine. Read more by following the link below.
