Lost queen ?

[mrbees2]

Have a very busy hive but can't find a Queen, I very often can't spot her in such a busy hive even though she was marked earlier this year. There is a lot of sealed brood and a great deal of pollen but not much in the way of larvae. Some of the larvae looks about 7 days old. (?) Feel she may of gone but looking for a glimmer of hope. Thanks

If you have no young larvae, nor eggs, and they're back-filling the broodnest with stores, she's probably gone.

Any sign of queencells in any stage ?

A test frame from your other colony may be helpful.

Larvae are capped after 5 days. Queen has gone then.

But I am going to be devil's advocate, queens do go off lay sometimes for a couple of weeks, the question is whether you want to take that risk. I would certainly be adding a test frame which in itself isn't a final decision maker but may point you in the right direction.

Sure about that?

Have you looked in the supers?

Seems to be 6 days. Queen has 5.

Pains me to say it, but he's right - egg hatches day three then five days later (day eight) larvae capped

are you able to move the brood box to the side and place a spare brood box in its place, wait 10 mins and then go looking for your queen, sometimes with less bees you will spot her,

I wonder is the OP referring to seven-day-old worker larvae, rather than charged queen cells ?
