This colony had 2 queens. About 6 weeks ago, both queens died with in 1 week of each other - I ID'ed them as queens. I did not rest them for the winter and had been pushing the temp into the high 80s during the day with 5 degree temp drop at night (Tucson is desert with many many 100+ degree days in the summer). The colony doubled in size and had a good mix of all phases of development. All workers appeared stuffed for food, clean water always available. Feed cricket frozen/thawed cricket parts, honey and grains.
Over the next 4 weeks, all eggs, larva, pupa continued to grow until there was only a couple dozen large developing pupa.
Then: Eggs started to reappear. In addition some of the eggs are now progressing to grow as larva.
There are now close to 300 workers busy taking care of everything. I can not see anything that looks like a queen (no wing scars, none that look abnormally big, ...).
