Hefting in the Wolf Moon

Went up after dark, which sounds romantic and was actually just when the luggage scale, the head torch, and I were all free at the same time. Full moon over the harbour, rime on the hive straps, both colonies silent until I put an ear flat to the brood box and heard it: that low, steady, furnace-room hum of a cluster keeping thirty-five degrees in the middle of January. Sixty thousand cold-blooded animals voting continuously to be warm. It gets me every year.

The midwinter audit, by numbers: luggage scale hooked under each side rail, lift until the far edge just floats, read, add the sides together for a rough gross weight. Lark came in around 24 kilos combined — comfortably heavy, her ivy stores barely touched. Vesper managed 19, and tellingly light on the seaward side, which means the cluster has been eating its way west to east and may strand itself away from its own stores in a long cold snap. Bees starve centimetres from food; cold clusters do not commute.

This is the same hive that went into autumn over the mite threshold, so her winter was always going to be the one I watched. So Vesper got the candy board — a shallow frame of set sugar slab laid straight over the top bars, eke above it, insulation back on. If the cluster reaches the ceiling, it finds dinner instead of a dead end. It is the cheapest insurance in beekeeping and I make one every Boxing Day out of superstition.

Condensation check while I was in there: Lark's crown board dry, Vesper's beaded at the corners despite the matching setups. Cold bees survive; damp bees do not. She gets a slab of insulation with the corners shimmed a few millimetres for airflow, and I will stop pretending I understand why two identical roofs breathe differently.

Plans drawn on the workshop wall for the year ahead: oxalic trickle for both on the next brood-free cold day, two spare brood boxes scorched by March, and a resolution — written in pencil, like all rooftop resolutions — to let Lark keep her swarm this year in a bait hive instead of fighting her for it. The gloaming comes early in January. By four the moon had the roof to itself.
