Ant factoids |
We have collected a few facts about ants that you might find interesting.
More are still to come. |
How much weight can an ant carry?
According to different
estimates, ants can carry 10 - 50 times their body weight! How? Because ants are
so small, their muscles have a greater cross-sectional area (they are thicker)
relative to their body size than in larger animals. Thus, they can produce more
force pound-for-pound (or in the case of an ant, milligram-for-milligram).
How many ants are there in the world?
Scientists have described over 12000 ant species.
Many more have yet to be discovered, especially in the tropics. The total weight
of all ants on Earth is close to that of humans. That’s pretty impressive
considering the average ant is about one-millionth the size of a human being!
Does the queen control the colony?
No. Despite her size and royal title, the queen doesn't boss the workers
around. Instead, workers decide which tasks to perform based on personal
preferences, interactions with nestmates, and cues from the environment. The
colony exhibits a division of labor where different individuals specialize on
different jobs. Younger ants often work inside the nest, taking care of the
queen and her brood. Older workers are more likely to go outside to gather food
or defend the nest against enemies.
How do ants communicate?
Ants communicate mainly using chemicals, which they sense with their
antennae. They release pheromones with specific messages, such as "Follow me to
food!" or “Attack the intruder!”. In addition, nestmates recognize one another
by chemicals on their bodies. The queen is coated with a unique blend of
chemicals that advertises her presence. Ants can also use touch and vibration to
communicate.
Are all ants pests?
No. Ants serve many roles in nature, some of which are beneficial to humans.
They eat other insects, pollinate plants, disperse seeds, move soil, and
circulate nutrients. Because ants perform all these functions, they are a key
component of many ecosystems.
Which hurts worse, an ant’s bite or its sting?
Usually its sting. The bite of most ants (except for really big ones) feels
like a weak pinch. But even tiny ants can deliver venom through their stings,
resulting in burning, itching, and/or swelling. Hence, names like fire ant and
bullet ant. Remember though that many ants don’t have stings and are more or
less harmless to humans.
