Iberian PeninsulaBroad documented localities — not a complete range map.
Iberian Peninsula and nearby western Mediterranean areas.
Dry grassland, scrub, field margins, paths and open agricultural landscapes.
Mostly diurnal in mild conditions, with seasonal avoidance of intense midday heat.
Seeds form the main food source, supplemented with arthropods.
Deep soil nests with granary chambers and strongly polymorphic workers.
What makes this species remarkable?
Cleared foraging trails can remain visible after workers have returned underground.
Granaries protect harvested seeds from rapid weather changes.
Worker size determines which seeds an individual can carry or open.
