Hello, here I will describe the progression of my 2 [later 1] Lasius niger queens/colonies. After a failed attempt to begin a Lasius umbratus colonie I waited untill the Lasius niger colony in my backyard had their nuptial flight [I waited a month ! ].
But at last on 10-07-2014 i've caught 2 wingless queens in test tubes, and a few days later they allready layed their first eggs !
And since then not much has changed, I think some eggs have hatched in the first larvea but there is not much more to tell.
The plan is to keep 1 of the 2 colonies and to sell or release the other colony.
Pictures are still comming and the next update will be when the first workers arrive .
