Found her this morning. At first I thought Pheidole, but she is really flat and small...maybe Tetramorium? AntWeb has the following documented species of Tetromorium in Northeast Florida.

T. bicarinatum

T. caldarium

T. simillimum

Thanks!

1. Location (on a map) of collection: Jacksonville FL
2. Date of collection: May 24, 2021
3. Habitat of collection: wooded area adjacent to recent development
4. Length (from head to gaster): ~4mm
5. Color, hue, pattern and texture: ridges on head (i.e. rugose)
6. Distinguishing characteristics: petiole and post-petiole, 2 spines on posterior mesosoma, club antennae

Not Tetramorium, looks like a Pheidole navigans queen to me.

I agree, she looks more like pheidole than tetrimorium.

Nylanderia parvula - 4 queen polygynous colony with larvae + devoloping workers

Camponotus pennsylvanicus - 1 queen with 2 cocoons, and a few larvae and eggs

Tetramorium immigrans - 3 colonies, first nanetics!

Formica pallidifulva - 1 queen, 8-10 eggs

Tetramorium atratulum - 1 queen with roughly 17 host workers

Pheidole pilifera - 1 queen! recently caught!

Solenopsis Molesta - 2 queens so far, polygenous set-up

Cool! Thanks! Anything particular distinguishing characteristics I can look for to distinguish Pheidole and Tetramorium?

Definitely Pheidole navigans. All of our southeastern Tetramorium species have queens that are much lighter in color and have a more slender build than the queens of Pheidole.
