[Hunter]

Found in Maine

Found by a damb with a lake on grass

Size is 6-6.5mm

Looks like camponotus but is half the size and was found in two locations by 2 difrent people 

its solid black with redish where its legs are

[VoidElecent]

Myrmentoma-group Camponotus queen; either Camponotus nearcticus or C. caryae.

its Camponotus Cyarae. nearcticus are all black

[VoidElecent]

its Camponotus Cyarae. nearcticus are all black

 

This is incorrect. The only distinguishable feature between the two species is the presence of erect hairs on the cheeks of Camponotus caryae workers, which C. nearcticus lack.

The tape measure in the picture is showing approx 5/8 of an inch which = 15.875 mm.

to convert inches to mm its (inches) x 25.4 = mm

On the cheeks of the workers!! Now that's detail!!      Sorry it just amazes me sometimes the things that differentiate species.

With those measurements, Camponotus pennsylvanicus, from a glance. Although your mention of "red where the legs are" might mean it's C. herculeanus or less likely C. chromaioides. (Again depending on the hair, C. chromaioides has a lot of long hair on their gasters, and the front portion of the gaster is typically red)

[rbarreto]

She seems very long and slender, the length confuses me but she still looks myrmentoma group to me. A side view picture may help.

Edit:
Buuuuuuut 16mm seems way too large. I don't know what to think.

Does nobody know how to read a ruler? That mark is the half inch line!

EDIT: that means that the measurements are presumably correct, although I would say she is more towards 7-8 mm.

DOUBLE EDIT: I’m going to say that she is Camponotus nearcticus do the the elongated gaster that Camponotus caryae lack. Also, Camponotus caryae from what I’ve seen tend to have orange/red in their thorax (I have a small colony of this species) which the queen also appears to lack. Still need a second opinion though.

No. Not 5/8 of an inch, 5/16 of an inch. Look at the ruler.

 

Once again, the only thing that differentiates the two species is erect hairs on the cheeks of C. caryae workers. Not gaster length. Not coloration.

You literally can't separate caryae from nearcticus without seeing the malar region of the head in close magnification, and both species are highly variable in color. VoidElecent is right.

As long as you don't misinform and let them know you're just guessing no harm done. Plus I believe being wrong is one of the best ways to learn.

[Alacom]

Based on the ruler pic, she is 3/8in long which would place her at about 9.6mm
