A colony's real health changes every day — mite loads build, brood patterns shift, stores rise and fall — but a beekeeper only knows what the last inspection recorded. This scene renders that gap directly: each hive box shows its recorded health from the last visit, while a small drone sweeps the yard on a fixed schedule, updating one hive's record at a time. Between sweeps, true health (shown as a translucent X-ray aura) can drift quietly away from what the logbook still says.
Many commercial beekeepers standardise on a 7–10 day inspection cycle during active season specifically because varroa mite populations can double in under two weeks — a longer gap between records means a much bigger surprise at the next visit.
A 3D apiary yard where an inspection drone sweeps hive to hive on a fixed schedule, updating each colony's recorded health — while true colony health quietly rises and falls between visits, exposing the surveillance gap that good record-keeping is meant to close.
Each hive shows two numbers at once: the recorded health from its last inspection (the box colour) and its true, continuously drifting health (the X-ray aura). Hidden declines — where reality has slipped well below the record — trigger a warning beacon.
Set the number of colonies, the inspection interval, and disease/mite pressure, then watch how a longer interval lets more hives drift into "hidden decline" before the drone ever catches up. Toggle the X-ray aura to compare record versus reality directly.
Varroa mite populations can double in under two weeks during peak season — one reason many commercial operations standardise on 7–10 day inspection cycles rather than checking hives only when something looks obviously wrong.
