Species Information:

Lasius niger are very commonly found all over Europe and some parts of North America and are a very robust species. Queens of this species are monogyne which means that there is only ever a single Queen in the colony. Lasius niger dominate a lot of the UK and are a very beginner-friendly species. Their nests are usually constructed underground and under stone slabs. The newly mated Queen will begin her life by digging a hole in the soft soil. After the Queen has dug herself a chamber in the ground she begins to lay tiny eggs. These eggs then develop through the larvae and pupae stage. Lasius niger larvae spin themselves a cocoon from in which they pupate rather than there being naked pupae. In the summer, brood is brought up nearer to the surface, underneath stone slabs, to increase the rate of development.


Lasius niger do well at room temperature when kept in captivity and should require no additional heating.
