👑 Queen Replacement Decision Framework

An interactive 3D brood-frame inspection that reads pattern quality, drone-layer symptoms and queenlessness to compute a live requeening urgency score and recommended action.

Entomology & Insect Behaviour3DAdvanced60 FPS

A live 3D brood-frame inspection that turns the signs beekeepers check by eye — pattern tightness, drone-layer cappings, and presence of eggs — into a computed requeening urgency score and a recommended action.

🔬 What It Demonstrates

Older, failing queens produce spottier brood patterns and more scattered raised drone cappings; a queenless colony stops producing eggs and starts drawing emergency queen cells. The scene combines these into one urgency score, then models how a chosen introduction method affects the colony's acceptance of a new queen.

🎮 How to Use

Drag the queen-age and drone-layer sliders to see the brood pattern degrade, tick "Queenless" to trigger emergency queen cells, then pick an introduction method and watch the worker cluster around the cage stay calm or ball up depending on how risky that method is for the situation.

💡 Did You Know?

Direct-releasing an unfamiliar queen into a colony that still has a viable, if failing, queen is the riskiest introduction method — workers frequently "ball" and kill her, while a slow-release candy-plug cage lets her scent spread first.
