    Default Please Diagnose what is happening in picture

    This is a friend's hive this morning. Bees are dragging out dead pupae. Some of the pupae seem to be almost fully formed. Any ideas what is going on here?

    Picture nots so great, but whatever is causing it is not good. Too much kill. Are the pupae drone, worker, mix? Hows the population and stores on the colony... I've actually never experienced somethign quite like your picture, I've seen pupae here are there maybe 5 at once but not something this large. It reminds me of pictures i've seen in the spring or early winter, chilled brood event.

    Is there a reason the entrance reducer is on? I usually only install reducers this time of year on very small colonies. It gets pretty hot and they need a bit more room, they actually start chewing at the reducer.

    i would guess they need food, It has been so dry and the nectar stopped coming in.
    Best of luck

    Probably all drones.

    It looks as though your hive has fallen over backward uprooting some earth with it.
    Get a good close up of the outcast brood and maybe we can give a more accurate assessment. it is difficult to tell if it is hygienic behavior, chilled brood, or something other from the pic.

    Thanks guys. Here are two more pictures. I plan on getting into the hive this afternoon. Anything in particular I should be looking for or taking pictures of to post here? Thank you for all the help.

    Went to friend's hive this afternoon. It is a colony that was installed from a 4 frame nuc on May 16. Population was good on his inspection Monday. Tuesday is when he noticed the dead larvae being pulled out by bees in first pictures. When we opened the box this afternoon, there were probably only 200 bees left and they all seemed very lethargic. I have attached 5 pictures of the frames. Please let us know what it is. Thank you.

    That's a seriously bad infestation!

    Wow. That's sad that they're so overpowered and yet desperately trying to bring out the dead. I haven't had issues with hive beetles up here, but I guess that's what hive beetle larvae looks like - did they kill the hive, or are they just taking advantage of a colony already on its way out?

    I think that is the key question. "What killed the hive?" The beek tells me that he did not notice a significant amount of SMH in the hive on the inspection Monday. The hive does not appear "slimed" in any way. Population was heavy on every frame on 3 days ago. Does anything look like something more sinister like AFB?

    You might want to post another: Is this American Foulbrood?

    I haven't had experience with that either, but I do know AFB will smell. Did the frames smell at all?

    I did not notice any smell

    There is not much honey in those pics, so it is possibly starvation, starving bees do throw out larvae.

    The beetle larvae are a symptom not a cause, we know this because they are very small newly hatched ones that have started after the hive already had a problem. In any case these larvae will grow super fast and make a heckuva mess, recommend immediate freezing of the combs, not tommorrow, today!

    I see nothing that would make me think AFB it simply looks as though they were overpowered by the SHB due to some underlying reason. Starvation, Low population. Varroa stress. Something!

    freeze those frames, here is the chance to kill thousands of SHB in one fell swoop!

    The next question psm would be: How much nectar/pollen stores in that hive? We could narrow down the starvation cause.

    I thought it was a substantial amount. There was some capped honey on almost every frame. Also open stores of nectar. They were building more comb on the outside frames and filling them too. Also, bees are still foraging here. I would not call it a "flow" necessarily, but we live in South Alabama and there is something for them to eat almost year-round. Cotton and soybean are coming up now. Not heavy nectar producers, but sources of nutrition. I just cannot believe that they starved in the middle of summer in South Alabama with capped honey and uncapped nectar in the hive. But I am learning that strange things happen in this hobby.

    Frames bagged and in freezer. Hive bodies scrapped off and left in sun to be picked clean by insects. I am assuming that, once hard frozen, the frames may be reused?
