Thanks guys: the Temnothorax call seems right. Upon comparing photos they look identical. In hindsight that “fruit” was obviously a gall, a favored home to this genus. I even caught a peek at what I believe to be the queen tonight: she was small but around twice the size of the workers and had a warm golden colored gaster. These ants are super shy so I usually only get a few seconds to scope them out. I’ll try and get a picture next time :) Go to the full post

Los Angeles County

Chantry Flats Trail Head

Santa Anita Cyn Rd

Sierra Madre,CA 91025

Date: January 5th

Habitat: Semi-arid desert/ lightly forested

Length: 2-4mm

Color: Black

Basic Description: Round Gaster, triangular thorax (top view), square head

Nest description: A dried out fruit attached to an unknown species of plant (a scrubby bush)

 

I found these little guys by surprise while on a hike with my brother. He happened upon a dried out fruit attached to a bush, cracked it open and found it teeming with tiny little ants (nanitics?) and eggs. I quickly snatched them up and placed them into a plastic container and have since moved them into a spare AntsCanada Formicarium. I haven't had any sighting of a queen yet but I am hopeful that she is hiding out in the center of the fruit considering how completely the ants swarm around it. Most of the ants will remain on the fruit except for the larger workers ants who are fairly active and quick to explore. I've witnessed them collecting sugar water and they absolutely devour meal worms but ignore crickets. I took some macro lens shots using my iphone:

Could also be veromessor andrei, but based on the size probably not.

-1x Parasitic Formica Sp. Colony

-1x Pogonomymrex Californicus Colony

-1x Camponotus Hyatti Colony

Nothing about this ant suggests V. andrei.
