On Aug. 28 2014 I caught a parasitic Formica queen - Formica emeryi (ID thread: http://www.formicult...meryi#entry4344).
Lovely colors. I boosted her with 6 or so pupae from a Formica podzolica nest, which she readily accepted. She did seem to need to eat every 24 hours though, or else she starting trying to get out. Once fed with hummingbird nectar she calmly sat with the pupae.
Most parasitic Formica in my location will not lay eggs until after hibernation. This lady was no exception. She went into hibernation in mid-September.
I pulled her out of hibernation early January. She laid a small batch of eggs shortly afterwards and the workers cared for them with no issues that I saw.
As of April 1, 2015, all 15 pupae have eclosed. Luckily, the host workers did not kill any of the new workers.
As of April 8th, only one host worker remains. I am not sure what happened to the rest, I do not see any bodies in the garbage pile.
