what's the difference between Camponotus pennysylvanicus and herculanus

 

 

According to antwik:  The majors of C. herculeanus can be separated by the shorter scapes and the relatively short appressed setae on the dorsum of the gaster (C. modoc has similar short setae). The females and majors of C. herculeanus can be separated as the scapes are shorter than those in the other 3 species, barely extending past the posterior lateral corner (up to the length of about the first funicular segment, extends more than the first funicular segments in the other 3 species). Unfortunately, the amount the scape extends past the corner of the head depends on the size of the major, with smaller majors having relatively longer scapes.

 

 

But a lot of the time herculeanus has more red, so I think most people go from the coloration.

I’ve never seen a C. pennsylvanicus specimen with red on it, so that’s how I would tell them apart.

If the queen has no red on the first gastric tergite then she is not considered as Camponotus pennsylvanicus. Their legs can be red.
