This colony came as a cast swarm from a feral colony in Collinwood Road, Risinghurst in May 2016. It was housed in Hive D.
It died in the spring of 2020. There appeared to be a Queen failure. The hive appeared to be occupied but the bees dwindled and eventually disappeared. There were no dead inside the hive and only the normal number outside*. The robbing gave the impression of activity where maybe there was none. The colony may have died much earlier than I had realised.
* There are usually quite a few dead outside all my hives in spring
