Dead larvae on entrance board.

[JP]

Just let the dogs out & went over & viewed my hives. My strong hive, has kicked out mostly formed larvae onto the bottom board. Some were fresh & white but fully formed, some were yellowish & fully formed but appeared to possibly have been dead longer. To reiterate, soft freshly killed larvae, as if they were just dragged out of their cells, & other larvae that appeared less fresh, I'm guessing, that they were dead longer, then pulled out of their cells. There were perhaps twenty all together, across the bottom board entrance.

Some additional info: Inspected hives two days ago, everything appeared normal, did notice bees were more aggressive,during this inspection, found queen, she looked fine. Feedback much appreciated. Thank you. JP

quick update, Just checked hive again & saw workers dragging more dead larvae again, in the latter pupal stages out onto the bottom board entrance. I took some samples & observed them. I see no mites & nothing particularly wrong with the larvae. I have sbbs & looked up into the bottom of hive & only saw a few dead larval bodies on the sbb. Seems like they are removing most of what they are pulling out of these cells. Hive one has none of this going on.

How did the hive smell.  If it has a sour, pungent odor you may have EFB.  I'm just saying this because of the yellowish color you were describing.  The only thing I'd find strange with this is that EFB affects the bees in the larval not pupal stage.  How many are there est. near the enterence?

Pupae are not larvae. Honeybee larvae look like fat worms. Pupae do not.

they were pupae approx. twenty, all is well today. they didn't have an odor. I e-mailed Michael Bush & believe he diagnosed the problem correctly. a few days ago I examined the hive & disturbed some in his opinion drone brood comb, & the bees were simply cleaning house by removing the damaged pupae. I can't tell if they were drones or not, but all is well today, Thnx Michael!!!
