Even though there was a great decline of bees on Earth due to the use of neonicotinoid and other pesticides, their importance was not underestimated on Calydon. Pesticide resistance was genetically introduced into bees, and they were allowed to naturally propagate across the space station.
Some bees have also been modified to collect and precipitate soluble iron, which gives them magnetic properties. These bees have been bred for use as ammunition for rail guns. Upon being fired, these angry insects recognize organic targets and will deliver their sting with increased accuracy.
