- Brood Boostable : Yes
- Hibernation : Yes, 3-4 months during winter months.

- Founding Stage Notes: During founding phase, queens prefer dark area's and will move brood into darker test tube if given chance. Without a dark area the queens tend to forage and explore more often, possibly stressing the queen unnecessarily. Blacking out test tubes with electrical tape seems to work best. After workers appear, they may be uncovered. Best to let them found with/in soil; Increases eggs produced. It's also very important to keep temp above 60F. They will stop laying eggs if nest is always below this temperature.
Every ant, even from same species may be temperamental to certain foods. Trial and error is best way to figure out she will eat. Compiled below is a list of likes and dislikes for this particular species.
