Drone Collection Cage is for honey bee breeders that perform artificial insemination of queen honey bees.  The Drone Collection Cage make catching and storing drone honey bees easy. There is a pivoting door to insert the selected drones through. The door pivots to lock drones in. Top and bottom are queen excluders, so the cage can be put in a bee hive and the workers will feed the drones through the cage until they are needed. When drones are needed the pivoting door is rotated to release the top queen excluder, which can slide up to open a small port where drones will crawl out one at a time.
This unit can also be used with the drone release cages and you can release the drones inside the mesh screen making picking them up easier.
