"Originally a marshland species, the 'Forest' Bee has since migrated to lusher forests. It continues to build in trees - a survival trick originally used to protect the hive from swamp water."
These are the different Traits that the Forest Bee can spawn with.
When a trait has multiple values one is picked randomly when the bee is created.
Although the Forest Bee is found naturally and already 'discovered' when the player starts the game, there is a hint listed in the game files:
This species builds elevated hives amongst the trees - look for camouflaged hives.
As this species isn't found by cross-breeding, Beenjamin doesn't give any hints for it.
When Cross-Breeding the Forest Bee with the following other species there is a chance for the offspring to mutate into a new species!
As with all mutations, the offspring of the hybrid queen needs to also be a hybrid, so this can effect the chances listed below.
