As the name suggests, these are bees that can be found in the more snowy areas of Wintreath, widely considered to actually be made of pure snow themselves. Though as one has never been caught (though many have been stung by it's icy sharp stinger), it's never been actually proven.
Making nests of snowy hives up in the corner of trees as well as other cold corners, Snowbees tend to find themselves helping Frostflies with pollinating the more unique cold flowers of Wintreath, their favorites being winter roses, frost daisies, crystal irises, as well as their favorite...the large prismatic cystal-petal flowers known as the Winter Gems.
In their hives, they are known for making a unique type of delicious ice-blue liquid that's come to be known as Frost Honey. It has a sweet flavor with a slight chill to it, and is used in many types of drinks including the Wintreath Delicacy known as the Winter Hammer Mach II.
Snowbees are much less wary of people than, say, Beeterflies. However, they will defend themselves if they sense that they're in danger, such as being swatted at...or especially if one were to try to take the honey from their hives.
Like regular bees, there are the many worker-drone Snowbees that pollinate the flowers and do most of the work while the Queen Snowbee gives birth to new Snowbees.
