Many people ask us how honeybees survive the winter...see below
There's a colony in the hollow oak at the edge of your property. You haven't seen a bee since October. You assumed they died.
They're not dead. They've been vibrating for 98 days straight.
THE WINTER CLUSTER:
When temperatures drop below 57°F, honeybees stop flying, stop foraging, and form a sphere around the queen in the center of the hive. This sphere — called the winter cluster — is a living furnace powered by muscle vibration.
Every bee on the outside of the cluster vibrates its flight muscles without moving its wings. This generates heat. The core temperature of the cluster stays at 92-95°F — even when it's -10°F outside.
They haven't eaten anything since early November. They're burning through honey reserves at approximately 30-40 pounds per winter. Every ounce of honey consumed is metabolized into heat through muscle vibration — the same biological process as shivering, except they've been doing it continuously for over three months.
THE ROTATION:
The bees on the outer shell of the cluster — the ones exposed to the cold — slowly rotate inward. The warm bees move out. This rotation happens continuously, so no individual bee freezes. The cluster pulses like a single organism, breathing in and out over hours.
If the honey runs out before spring, the cluster shrinks. The queen reduces her metabolic rate. The outermost bees stop vibrating and die — sacrificing themselves to keep the core warm for a few more days. They die in formation, still holding the sphere.
WHAT KILLS THEM ISN'T COLD:
It's isolation. A wild colony in a tree hollow — insulated by 6 inches of deadwood — has a survival rate of 70-85% in normal winters. A managed colony in a thin-walled commercial hive box has a survival rate of 50-60%.
The dead trees you remove. The hollow limbs you prune. The snags you cut down for looking "unsafe." Those were insulated apartments built by 60 years of woodpeckers and rot. A 4-inch cavity wall is worth more to a bee colony than any commercial insulation wrap.
THE NUMBERS RIGHT NOW:
→ Approximately 30,000 wild honeybee colonies exist in natural tree cavities across the eastern US
→ Each colony pollinates an estimated 300 million flowers per season
→ Wild colonies are genetically more diverse — and more disease-resistant — than managed hives
→ Every hollow tree removed is a cavity that won't be replaced for 40-60 years
They've been vibrating for 98 days. They'll vibrate for 30 more. And then they'll fly out into a world that has fewer flowers than last year and fewer hollow trees than the year before that.
They're still alive in there. All 10,000 of them. Humming.

We like to think we’re contributing. Keep it up folks.
This is a nice reminder that all the small things you do for the environment are making a huge difference! 🦋🦋🦋🦋🦋🦋
Keep planting Milkweed, stop unnecessary spraying, and leave the leaves! 🍂

nature will
fix itself if we stop fighting it
Here's a genius way #milkweed distributes its seed. #nativeplants #themoreyouknow #willcounty

taking some heat over here 😇
They can vilify us all they want. To be a true leader takes guts!!!

i explain this so often to people - not 🐝 but they are pollinators.
These are hoverflies. Though often misidentified as "sweat bees," they are not bees. Unlike true sweat bees, they cannot sting (or bite). But, you can sometimes feel them licking -- they're after the salt and water in your sweat.
These flies are pollinators too.
You'll see less of them as we enter the gap between summer and fall. So enjoy them for just a bit longer 😊🐝

so obvious to us!
Sad reality! 🥲
