I am pretty sure that the queen I found is L.umbratus and I attached a tube of L.niger workers with cocoons and at first the queen showed aggression but then she walked into their tube and now the workers are licking her!!
Awesome! Let us know how it goes! :)
I took them out of the fridge and a worker latched on to the queens antennae!! but I removed this rowdy worker and the rest seem fine with it. :)
:( the wokers turned on her and I got there just before the queen died, she is now reviving with a drink of honey water, hope she makes it :). I think that I was supposed to let the workers sit for about a week so they realize that they are orphaned and that makes it easier for them to be adopted. I will try this. Anyone how has had experience with these please help!
