It turns out that bats, along with birds and bees (insert convoluted reproduction joke), are in the business of pollinating plants and flowers.  How about that.  I knew those fuzzy little swimming creatures must exist for purposes other than eating bugs and scaring people. 

[On a side note, that Forest Service link also contains this gem:  "The agave is an important plant because it is used to make tequila."  Ah, priorities.]
