🐝 Ethical Beekeeping: Colony Welfare Lab

About this simulation

Ethical beekeeping balances a beekeeper's interest in honey with a colony's own needs: enough stores to survive winter, low disease pressure, and minimal disturbance. This lab runs a simplified colony model continuously — nectar comes in on a seasonal rhythm, honey is consumed and (optionally) harvested, varroa mites build up or are controlled, and colony health responds to all of it.

How it works

• Winter stores — honey kept in the comb. Nectar flow adds to it each simulated day (strong in summer, weak in winter); the colony eats from it constantly, and harvesting removes more.
• Colony health — drifts toward a target set by stores adequacy, mite load and disturbance. Starving, mite-heavy or frequently-disturbed colonies decline; well-buffered, well-managed ones recover.
• Varroa mite load — grows fastest when untreated, is held low by integrated pest management (IPM), and is suppressed hardest — but with a small residue cost to bee vigour — by heavy chemical treatment.
• Ethical practice score — a rough index combining harvest pressure, mite management choice and disturbance frequency, the same trade-offs a real ethical beekeeping standard weighs.

Controls

• Honey harvest rate — how much surplus honey you take once stores exceed the colony's safety reserve.
• Inspection disturbance — how often and roughly the hive is opened and inspected; agitates bees and stresses the colony.
• Varroa mite management — none, ethical IPM, or heavy chemical treatment.
• Season — sets nectar inflow and forager activity outside the hive.
• Simulation speed — how many simulated days pass per second. Drag to rotate the hive, scroll to zoom.

Did you know?

Many ethical beekeeping standards require leaving a minimum weight of honey per colony before winter — taking a "surplus only" approach rather than harvesting everything and feeding sugar syrup back, because syrup lacks the micronutrients bees evolved to use.
