Messor Wasmanni - Beginner Species - Medium in Size

The Burgundy Harvester  (Heat may be required)


The Messor Wasmanni is a nice variation of harvester which has a deep purple / burgundy thorax under light. This species is slightly smaller than the popular barbarus but once established has a very different look and behaviour.


Found in the most southern parts of Europe, our Wasmanni is sourced in Greece but they span all the way to norther Africa and the middle east too. They love higher temperatures of 25-30 degrees and are typically found in arid environments.


In addition to being pretty ants they are also almost entirely grainivorous. They primarily and almost exclusively eat seeds and grains with very little need for additional protein. Wasmanni have been noted as only taking insects if one poses a threat on a trail or a dead one is found.


Harvested seeds are eaten by the ants, using the large Majors jaws to de-shell them. They are then chewed into a protein rich food source known as "ant-bread". It is this ant-bread Wasmanni get 95% of their nutrients from.


Wasmanni are also Polymorphic. They will produce larger majors who can split the toughest of shells and defend the colony.


Harvesters make great beginner species. It is worth noting however that they do require a humidity gradient to store seeds in a dry section of the nest. They are also prone to drowning, open water sources should be avoided in favour of ones which use mesh or cotton.
