A summer worker bee lives only 2–5 weeks: she forages hard, burns through her flight muscles, and accumulates oxidative damage fast. A winter bee, born in autumn, can live 4–6 months by skipping foraging and brood-rearing almost entirely and instead loading her fat body with vitellogenin — a yolk protein that also acts as an antioxidant and nutrient reserve for the whole cluster.
Because winter bees barely fly or feed brood, their vitellogenin never gets diverted to jelly production — it simply accumulates, doubling as both a nutrient bank for the colony and a powerful antioxidant that slows the bee's own aging.
A honey bee's fat body glows gold with vitellogenin, a protein that doubles as an antioxidant reserve — watch it deplete over a simulated lifetime, faster under high foraging workload, slower when a winter bee stockpiles it instead of feeding brood.
Summer foragers burn oxygen fast and drain vitellogenin quickly, dying of accumulated oxidative damage within weeks. Winter bees barely forage, keep vitellogenin high, and can live four to six times longer.
Pick summer or winter, adjust foraging workload and vitellogenin titer, then scrub the day slider (or press Auto-age) to watch the fat-body glow fade, red oxidative-stress sparks build up, and wings fray as the bee ages.
Vitellogenin was originally an egg-yolk precursor protein — worker bees repurposed it as a nutrient bank and antioxidant, one of several unusual re-uses of reproductive machinery behind extreme differences in insect lifespan.
