Ant species you can keep in a Forest Starter Set
The sizes of the starter sets (S, M, L) differ only by the distance between the plates of the ant farm and the size of the holes for the connection to ant houses and other ant farms (both according to the size of the ant species).
S = 6 mm for small species like Myrmica
M = 10 mm for medium species like Lasius and Formica
L = 20mm for large species like Camponotus with nest insert also for smaller ant species.
