Hello,

 

First time Poster here. Can someone please confirm that these are pavement ants? Photos are of one worker in detail and then one dorsal shot of the queen. 

 

Thank you,

Sorry got excited and didn't follow instructions

 

1. Location (on a map) of collection: Tulare, California
2. Date of collection: 2/26/25
3. Habitat of collection: Under a rock on edge of parking lot
4. Length (from head to gaster):3mm roughly
5. Color, hue, pattern and texture: light brown/amber. queen brown
6. Distinguishing characteristics: spines on thorax, 2 node petiole. 12 segmented antennae
7. Distinguishing behavior: Found multiple queens under same rock
8. Nest description: nest under rock on the edge of parking lot

9. Nuptial flight time and date: didn't see flight, wings already removed upon finding.

 

I am trying to rear them in test tubes until they lay more eggs. 

 

Is it advisable to catch workers to jump start the colony?

I will let someone more adept with microscopic ID's answer your ID question, but as to the care of Tetramorium immigrans, you do not need to boost the colony as they grow super fast as it is. You can check out this journal by RushmoreAnts: https://www.formicul...-1125/?p=242217for more information and to compare queens.

Pheidole hyatti: flattened and expanded scape bases (cylindrical in both P. desertorum & P. vistana), short scapes (long in P. vistana), striae on frons restricted more or less to lateral margins (striae present more or less across entire fron region in P. desertorum & P. vistana).
