The Beekeeper’s Diagnostic Lab & Triage Command Center
Over 60% of beginner beekeepers lose their colonies in their first two years due to inspection panic, undiagnosed Varroa mites, and winter moisture condensation. This interactive diagnostic suite gives you instant, scientific clarity so your colonies thrive.

Day 1–3 Egg (Queenright Indicator)
A tiny white grain of rice standing vertically at the very bottom center of an open wax hexagonal cell. By day 3, it tilts to 45° before hatching.
Proof that a mated, laying queen was present in this hive within the last 72 hours! You DO NOT need to spend 20 minutes looking for the queen if you spot fresh eggs.
No action needed. Confirm the colony is Queenright and close the hive gently to prevent chilling the brood.
Searching every frame for the queen creates stress, rolls bees, and risks crushing her. If you see single upright eggs in cell bottoms, she was there within 3 days. Your hive is queenright!
