Quick answer. Messor capitatus is a Mediterranean harvester ant with glossy black workers and majors with very prominent heads, cared for just like Messor barbarus: a seed diet, a rather dry environment with a humid area for the brood and a temperature of 20 to 28 degrees in the active season. It takes a winter rest, although less marked than northern European species. It's as rewarding as barbarus and visually different, so it's a good second colony for anyone who already knows how to care for harvester ants and wants some variety without changing their routine.

What the species is like
Like the other Messor, it organises its life around grain: it collects it, stores it in dry chambers, grinds it and carries the waste out to the foraging area. The majors, with big heads and powerful mandibles, handle the hardest seeds.
The typical mistake is too much humidity in the storage area: the grain sprouts, mould appears and the colony suffers.
What the colony needs
A nest with a large dry area and a humid spot, plus a foraging area to leave waste in. The Dry models and the standard ones in the Terra range both work, depending on the humidity in your home. For grain, small mixes such as chia.
Frequently asked questions
Where can I get it?
At AntMaster it costs €0: a fertilised queen, in Free Ants, depending on seasonal availability.
How does it differ from barbarus?
In the look of the workers and a somewhat different growth rate. Care is practically the same.
Does it need insects?
It doesn't need them, but they speed up brood development if you give them every now and then.
