When determining whether a bee colony died from starvation or robbing, specific physical signs in and around the hive provide clear distinctions. Starvation leaves behind a cluster of dead bees with heads still in cells (attempting to feed), minimal honey reserves, and no wax capping debris. Robbing, however, creates chaotic hive entrances with fighting bees, chewed wax flakes, and ragged comb damage from intruders. The timing of bee deaths also differs—starvation often kills bees simultaneously, while robbing leaves scattered casualties over time.
Key Points Explained:
-
Hive Honey Stores
- Starvation: The colony will have little to no honey left in the comb. Bees consume all available resources before dying.
- Robbing: Honey may be entirely gone, but the comb will appear torn or ragged from robber bees ripping open cells.
-
Bee Body Positioning
- Starvation: Dead bees are often found with their heads inside empty comb cells, a last-ditch effort to find food.
- Robbing: Dead bees are scattered near the entrance or bottom board, often with signs of physical altercations (e.g., missing limbs).
-
Wax Capping Debris
- Starvation: No wax flakes on the bottom board, as bees did not uncap honey stores.
- Robbing: Chewed wax cappings litter the hive floor, a byproduct of robber bees breaking into sealed honey cells.
-
Comb Condition
- Starvation: Combs remain intact but empty.
- Robbing: Combs are shredded or damaged from aggressive foraging by robbers.
-
Timing of Deaths
- Starvation: Large numbers of bees die simultaneously, clustered together.
- Robbing: Bee deaths occur over days, with fewer corpses at a time.
-
Hive Entrance Activity
- Starvation: No signs of recent activity; the colony perished quietly.
- Robbing: Evidence of chaotic fighting (e.g., bees wrestling, wasps present, heightened aggression).
Understanding these differences helps beekeepers diagnose hive failures accurately and implement preventive measures, such as supplemental feeding or robbing screens, in future seasons.
