Found my 3rd absconded colony since September today. Similar pattern to others, none or very little brood, lots of stores, none or very little sign of varroa, no dead bees in hive, was a good strong colony. One of our neighbouring associations has recently posted a question to others about this subject having many members losing colonies the same way for no apparent reason. I wonder what is going on. I have never lost more than 1 like this in a year and probably only 2 or 3 in 12 years
