Swarm

Colony of bees in a jacaranda, originally uploaded by Pica Rosa.

Such is their toil and such their busy pains,
As exercize the bees in flowery plains,
When winter past and summer scarce begun,
Invites them forth to labor in the sun.
Some lead their youth abroad, while some condense
Their liquid store, and some in cells dispense:
Some at the gates stand ready to receive
The golden burden, and their friends relieve;
All, with united force, combine to drive
The lazy drones from the laborous hives,
With envy stung they view each other's deeds;
The fragrant work with diligence proceeds.

--Vergil Aeneid I
