It's important to consider Landform Specialty, Moods, and Likes/Dislikes of your Bees. Matching these factors provides additional mission boosts and improves your Bees' performance.
You also need to consider your Bee's Endurance stat as that affects which Zones your Bee can reach.
Don't forget to claim the rewards your Bees gathered for you via the "Rewards" tab in-game.
REMINDER: Likes, Dislikes, and Moods are randomly assigned when the Bee is born (whether it is Hatched or is the offspring from Breeding).
