To identify what's on a frame:
1. Finding Eggs: Find a frame with drawn comb, but NO CLEAR SHINY LIQUID in the middle.
Stand with the frame held over the hive, but the sun or most light coming from
behind you. If there's eggs, you'll see 'em.
2. Finding Larvae: Look next to capped brood (CWB below), and look for milky liquid in the cells.
3. Finding capped brood: AKA CWB for capped worker brood. It is in the middle of the frame, with a solid not translucent capping, that looks like toffee.
4. Finding Nectar: It's clear and shiny, fills cells to the top, and is either at the top of the frame, or fills the whole frame.
Notice I didn't mention honey. It will be found where nectar was, later in the summer. Initially the bees are pretty focused on construction, rather than on savings.
I do remember my first time opening the hive. I was feeling...unsure of the situation. ;) All those stinging insects staring at me... I was gentle, it was fine. If you don't act like a bear, the bees will for the most part ignore you. I have the smoker going in case I crush a bee, drop a frame, or the inner cover - it happens, the bees forgive us, we move on.
