A healthy pattern is a solid oval of capped brood near the middle of the frame, with few skipped cells, ringed by pollen and then honey toward the edges. That arrangement — brood in the centre, pollen around it, honey at the corners — is what a well-organised colony builds, and it tells you more than any single cell does.
How solid is solid enough?
Perfect is unusual. A good frame has capped brood filling most of the oval with occasional gaps. If you can cover most misses with a few fingers, that's fine.
What you're looking for is continuity. A queen lays outward in a spiral, so healthy brood appears in bands of similar age. Eggs in the middle, larvae around them, capped brood outside that.
What does spotty brood actually mean?
Not automatically a failing queen, which is where people jump too fast. Spotty brood has several causes:
- Hygienic behaviour. Bees that detect and remove diseased or mite-infested pupae leave gaps. That's the trait working as designed — it's a good sign, not a bad one.
- A failing queen. Running out of sperm, poorly mated, or old.
- Disease. Chalkbrood, European foulbrood, sacbrood.
- Chilled brood. Often from an inspection on a cold day, or a colony spread over too much space.
- Inbreeding. Poorly mated queens produce diploid drones that workers remove, giving a distinctive shotgun pattern.
Our colonies are selected for hygienic behaviour, so some gapping in our stock is expected and desirable.
How do I tell hygienic removal from a bad queen?
Look at what's around the gaps. If eggs and young larvae are dense and evenly laid but capped brood is patchy, the queen is laying fine and the bees are removing things afterward. That's hygiene.
If the eggs themselves are scattered — skipped cells, uneven distribution, cells missed in the middle of the pattern — that's the queen.
What are the warning signs I shouldn't ignore?
- Sunken, perforated cappings with a foul smell — possible American foulbrood. Get it identified.
- Ropy, coffee-coloured larvae that stretch when probed — same.
- Multiple eggs per cell, stuck to cell walls — laying worker, colony has been queenless a while.
- Drone brood scattered through worker cells — drone-laying queen. She needs replacing.
When should I requeen over pattern alone?
When the pattern is genuinely poor, the colony isn't building, and you've ruled out disease and chilling. In a northern season, do it early enough that the new queen has time to build a winter population — by August that window is closing fast.
