My son collected FOUR queens from the exact same species and each of the four are thriving in their respective test tubes with between 10 and 15 workers.
Had a bit of hard time getting good pics but I think this one below is the best and captures the features adequately. At first we thought they were Tetramorium but because of the redish thorax on the queen I now think they are Camponotus.
1. Location of collection:
Ottawa, Ontario, Canada.
2. Date of collection (more important for ID's of queens):
Caught mid-June
3. Habitat of collection (ie: desert scrub, oak forest, riparian, etc.).
Most of the Queens were caught in or near a mall Parking Lot (with some small bush islands). One in slightly wooded area near houses.
4. Length:
Queens: 13mm
Workers: 5mm
5. Coloration, hue, pattern and texture:
Mostly black but Queens have distinct dark reddish hue on top of thorax.
6. Distinguishing characteristics:
One petiole as far as i can tell. Yellowish segmented gasters (lined?) that look more prominent on workers than on queen.
