I clearly spotted my queen for the first time last week and saw no odd comb building like queen cells. This hive started as a new nuc one month ago in Oklahoma City. I've been feeding them a lot of sugar water. I struggled to find the queen this week but I may have e seen her on a new frame with partially built comb. What's your opinion is this is my queen? Also, what is this odd build out? It almost seems like a queen cell but it's in the middle of a frame.

I am in Oklahoma City, US. It's been 16 days since I installed a 5 frame nuc. My other frames have added wax and I sprayed them all with sugar water before installing the nuc. I haven't put on the honey super. Ive been putting bags of sugar water inside every week which the bees are consuming. My question is when I checked the bottom board of my screened bottom, I saw live larva. The frames were maybe 60-70% filled with capped and uncapped larva. Are these bee larva or some other larva on my bottom board? Is there any action I should take or leave them alone ? Thx
