The Acorn Ant is a tiny ant that nests inside hollow acorns, nutshells, and small wood cavities in forests. Entire colonies with queen and brood fit inside a single acorn cap. It is a model organism in studies of collective decision-making — when a nest is destroyed, scouts evaluate potential new sites and lead the colony to the best option through a quorum-based process.
