I had suspected that this colony was unsuccessful requeening itself after swarming 2 months ago. The activity had declined noticeably over that time. Now they are being robbed at 6am by several colonies on my yard. Once the event is over, it will give me a chance to take the spool apart and see what’s inside. Thankfully, I have many descendants of the original queen that came along with this colony, including the atleast 2 year old queen herself in a booming healthy colony.
Ohh, sorry they’ve not made it. But as you say, they’ve reproduced effectively so not “lost”. It’ll be fascinating to see what they’ve done inside the spool…
