My daughter and I opened our hive today to try to make sure our queen had not flown away four days ago when we direct released her into the hive (we were uncertain). The bees had been in the hive for about six days.
We were not able to spot the queen, in part because of the layers of bees around the forming comb. Unfortunately, during the inspection a piece of comb fell out (even though we were trying to be very careful to not tilt the foundationless frames - I felt terrible about this ).
On the plus side, we were able to inspect that comb, and it looks like there are larva in there.
OTOH, I read on perfectbee.com:
Worker bees are female and can lay eggs as well. But because they do not take a mating flight their eggs are unfertilized and they will only produce drones. The queen is the only bee who can create both male and female bees.
Here is a picture I took of the comb, with the larva in it. Does this prove we have a queen, or could these be worker larva?
