Ants are social insects of the family Formicidae and, along with the related
families of wasps and bees, belong to the order Hymenoptera. Ants evolved
from wasp-like ancestors in the mid-Cretaceous period between 110 and 130
million years ago and diversified after the rise of flowering plants. Today,
more than 12,000 species are classified with upper estimates of about 14,000
species. They are easily identified by their elbowed antennae and a
distinctive node-like structure that forms a slender waist. Ants form
colonies that range in size from a few tens of predatory individuals living
in small natural cavities to highly organised colonies which may occupy
large territories and consist of millions of individuals that are mostly
sterile females forming castes of "workers", "soldiers", or other
specialised groups. Ant colonies also have some fertile males called
"drones" and one or more fertile females called "queens". Ants have
colonised almost every landmass on Earth. Ants dominate most ecosystems, and
form 15–20% of the terrestrial animal biomass. Their success has been
attributed to their social organisation, ability to modify their habitats,
tap resources and defend themselves.

Wikiquote quote of the day:
If the general government should persist in the measures now threatened,
there must be war. It is painful enough to discover with what unconcern they
speak of war and threaten it. They do not know its horrors. I have seen
enough of it to make me look upon it as the sum of all evils. --Stonewall
