All honeybees in a colony share nearly identical DNA, yet their lifespans differ by two orders of magnitude. A summer worker wears herself out in about six weeks; a queen, fed only royal jelly and never leaving the hive to forage, can live for several years. This lab turns three of the biggest drivers of that gap — activity level, nutrition, and thermal/environmental stress — into sliders, and shows the resulting lifespans as three glowing towers plus a bee that visibly ages in front of you.
Summer "wear it out" workers and long-lived winter bees are the same species and genome — winter bees simply do little flying and stockpile vitellogenin, a protein linked to both immune function and longevity, letting them survive many months until spring brood-rearing resumes.
Three glowing towers represent the lifespans of a worker, a drone, and a queen honeybee, while a bee in the foreground visibly ages — its wings fraying and colors dulling — on a fast-forwarded loop driven by the same biological factors that shape real bee lifespans.
Activity level, nutrition quality, and thermal stress combine to produce wildly different lifespans from nearly identical genomes — a summer worker's six weeks versus a queen's several years.
Pick a focus caste, then drag the activity, nutrition, and stress sliders. Watch the three towers rescale and the foreground bee's aging speed and appearance change in real time.
Winter "diutinus" bees are genetically identical to short-lived summer workers — by foraging less and stockpiling the protein vitellogenin, they survive many months longer.
