I didn't have a way to get a photo this trip, drat! There is about 100 larvae of different development stages, different sizes, outside the hive on the porch and ground. Some are pure white, some are tinted creamy, some look kinda dried up. I think this is A LOT of brood to kick the bucket.
three stack hive, top box full of honey.
No mites, OA treatments in the fall, sticky board shows 3 dead mites, no wigglers.
A week ago, I went down to the second box, no brood, but plenty of healthy bees. So I'm thinking there is capped brood in the bottom box. 4 nights ago we had a snap wind and freeze night below 20 degrees. The entrance to the hive is blocked to 2 inches. I'll bet the brood was close to the bottom of the frames and got chilled and some frost bitten. Also found that by accident the inner cover was put on backward where the notch then faced the opposite direction than the entrance. Sooo, that would make a pretty good cold gale going up thru the hive.
The hive doesn't seem to be any worse from it, and good thing I caught it right off the bat.
