Solenopsis molesta, the thief ant, is one of the smallest, but also underrated ants. They're called molesta for a fairly good reason. One of their main food sources comes from going into the brood chambers of other ants, paralyzing the workers, and making off with the brood. These queens are just 3-4mm long, and workers can be as small as 1mm. They require very high humidity and will dry out easily, but are otherwise a fun and easy to keep species.
You might be wondering why we only sell queens in multiples, and not one-by-one. In our experience, Solenopsis molesta seems to more than double the survival rate and worker count when in multiples. However, I do not recommend founding queens in groups of larger than 5 queens. Rather, for a larger colony, keep groups of 5, and merge them right as workers begin to emerge.
