Over the past couple of weeks I have caught a handful of parasitic Lasius queens in the UK as they have their flights. Tonight I filmed the minutes after introducing a queen to a small young niger colony I own, no cooling was used and I kept the original queen in place. Anyway I filmed the results, the video starts with niger queen on the right.
