How it works

The robbing-risk score is a weighted blend of four real beekeeping risk factors, each normalised to 0–100 and combined the same way a risk checklist would:

timeRisk     = 100 − |timeOfDay − 50| · 2   (peaks at midday)
dearthRisk   = dearth
strengthRisk = 100 − colonyStrength
feederRisk   = 85 (open dish) or 18 (enclosed)

risk = 0.35·timeRisk + 0.28·dearthRisk
     + 0.20·strengthRisk + 0.17·feederRisk

Guard-bee count scales linearly with colony strength (2 at a weak colony, up to 10 at a strong one). Robber bees spawn from the field edge at a rate proportional to risk; each one is intercepted at the entrance with probability equal to guard effectiveness (colony strength). An intercepted robber is repelled; one that gets through steals from the feeder before fleeing.

Scent plume — the translucent amber ring around the feeder; its radius grows with risk, visualising how far the sugar scent carries.
Guard line — amber dots at the hive entrance; their count is the live guard readout.
Robber bees — red dots approaching from the field edge; green flash = repelled, red flash = successful robbery.
