  • Formica truncorum are arguably rarer than formica rufa to see for retail and are very easy on the eye with their beautiful red and brown contrasts of colour.


    This species can be found in Europe, Italy including places like Japan. Because they are normally found in high altitudes in mountainous areas, they are usually a lot harder to find and require in depth knowledge and luck to find the queens.


    In the wild like Formica rufa they can form satellite colonies in which the colony occupies multiple nest spaces with multiple queens. They also have the tendency to nest inside tree stumps.


    The two ways in which a colony grows is by splitting via the satellite nest method or second in which the Formica truncorum queen invades the nest of another formica species and kills the queen such as fusca and takes over the colony, so its classed as parasite queen.


    Our Formica truncorum come with fusca slave workers.


    In the wild they can also accept queens from outside the colony but often is the case they adopt queens back into the colony once they have mated to increase the population of queens.


    A truly amazing and rare species with beautiful colourations a must have for any ant collector.

    Be aware of sellers only using the Live arrival guarantee and not the 14-day additional warranty on European ant species it might be slightly cheaper but could end up paying more in the long run, also all our products are sold as starter kits including food and a pipette.

    We do require photographic evidence of the queen in the original test tube for validating the guarantee once outside the test tube and in a nest the environment is outside of our control.

    It is illegal to release non-native species of ants into the wild and could damage the local ecosystem so bare this in mind we have a duty to our environment.


    Live arrival guarantee we ensure the live arrival of the queen only upon delivery contact us within 24-48 hours of receiving the Queen dead on arrival with a picture of the dead queen and the original workers. DO NOT TRANSFER THE DEAD QUEEN OR WORKERS TO A NEST AS THIS VOIDS YOUR WARRNTY. For our additional 14-day guarantee for European species the Queen and workers must be kept in the original test tube sealed with the cotton and care sheet instructions followed if you want to keep this additional guarantee do not transfer to a nest or your warranty is VOIDED (we recommend you keep the 14-day warranty).


    We have no control over the environment outside the test tube and have no influence in the conditions the responsibility once placed outside the test tube within the 14-day period the responsibility is with the buyer. 9 times out of 10 colonies die in the nest due to lack of water access, food, temperature, oxygen, or stress due to vibrations or exposure to excess light. If your colony does fail inside a nest contact us, we can advise what went wrong but it is up to you to buy another ant colony, you will succeed but sometimes it does not work the first time. Research is key to success with ant keeping and follow our guides.
