Hello James,
Welcome to the world of beekeeping. I hope you're having fun!
What is you current hive setup. Do your bees have enough space? You mentioned that you're a new beekeeper, are these colonies that you started this year from a package or a nuc or are these overwintered colonies that you had last year?
If both of your marked queens are missing and you aren’t seeing eggs or larvae, it's possible your colonies have swarmed. Typically, bees swarm soon after queen cells become capped, which aligns with what you're describing.
Are you able to determine if the queen cells you saw were swarm cells or supersedure cells? This guide should help identify the type:
Supersedure Cells vs Swarm Cells
If they're supersedure cells, your bees are likely replacing their queen—though it's uncommon for both colonies to supersede simultaneously.
Since you now have capped queen cells, it's best not to disturb the hives for a while, allowing the new queens time to emerge, mate, and begin laying. Using a queen dial (
such as this one), and assuming the cells were capped around your post date (5/26), the earliest date you'd see new eggs would be approximately 6/10, though it's safer to check between 6/11 and 6/17. Keep in mind this timing is approximate, since we’re uncertain exactly when the queen cells were capped. Queen cells will be capped for 7-9 days before emerging so this can impact the prior timeline some since we don't know exactly when they were capped.
Edit: Peter thanks for catching the typo with my dates.
