Here’s an interesting article that suggests that bees try to protect their hive from toxic pollen. They cap the pollen to try and keep it isolated from the hive. Alas, they are ultimately not too successful and researchers have been finding these odd capped cells in hives that died. The bees that work inside the hive notice the presence of pesticide once the pollen is in the hive, and they try to cordon off the area. Poor bees. The presence of these cells is a great indicator that your hive will die. Sheesh. I hope our hives are doing ok. It’s too cold to get out there and do our spring check in.
The odd grey cells are the ones to look for.
