Why Do Ants Die After the Queen Dies?

Eduardo Fox:

A fundamental fact about social Hymenoptera (wasps, ants) that most people, including entomologists, are unaware of: They cannot live without their larvae.

Next time you see an ant’s nest, a bee hive, or a hornet’s nest, remember: That structure is essentially a neonatal ICU!

Why? Look at an ant’s body below:

Did you notice the waist? I tell you: The individual’s stomach is located after the thin waist. That means an ant cannot eat solids.

Now, take a look at an ant’s larva (a & b, below):


Notice the waist? There’s none. It means larvae eat solid food!

So, this is what happens: Ants are working hard together in that nest mainly to bring up hundreds of babies. They come out to get food and bring it back to the nest, then they chew it up and place it on their larvae. Larvae will swallow and digest the food for them. Especially protein. Larvae secrete nutrient-rich liquids back to the ants, which is their main source of amino acids and fatty acids.

Who lays eggs to produce larvae? Queens.*

What happens when queens die? No eggs, hence no larvae.

What happens when there are no larvae? Bad nutrition, ultimately no reason for the nest. Ants gradually get disorganized, and after a few weeks they die.

Wasps and more "primitive" ants can more easily produce a new queen who will be the next mated female in the hierarchy. However, if none of them is fertile enough and mated, the nest won’t last long. Bees work differently.

* Important technical notice: Queens normally live longer than workers. Nowhere in this answer did I mean to imply that larvae can somehow enable workers to live as long as queens!

Why Did Noon Used to Mean 3 p.m.?

3 p.m. is basically noon for people who wake up at 12 p.m.

If you’re a late sleeper, you might find yourself thinking 12 p.m. seems way too early to be considered midday, and the word noon would much better describe, say, 3 p.m. It turns out that ancient Romans would have agreed with you, if only for etymological reasons.

As Reader’s Digest explains, the days in ancient Rome were split into four periods of three hours each. The first hour was at sunrise around 6 a.m.—called prime, for first—followed by 9 a.m. (terce, denoting the third hour), 12 p.m. (sext, for sixth), and 3 p.m. (none, for ninth).

According to Merriam-Webster, Middle and Old English borrowed the time-keeping tradition, along with the Latin word for ninth, which was changed to nōn and eventually noon. Though we’re not sure exactly when or why noon started referring to 12 p.m. instead of 3 p.m., it could have something to do with Christian prayer traditions. In the Bible, Jesus’s crucifixion is said to have taken place at the ninth hour, and that’s when worshippers partook in their second of three daily prayers; the others were in the morning and evening. It’s possible that hungry monks were behind noon’s gradual shift from 3 p.m. to 12 p.m.—since their daily fast didn’t end until after the midday prayer, they had a built-in motive for moving it earlier.

While we didn’t exactly stay true to the original Latin meaning of noon, there’s another important remnant of ancient Rome hiding in the way we tell time today. Romans referred to 12 p.m. as meridiem, for midday, and so do we. A.M. is an abbreviation for ante meridiem, or before midday, and P.M. means post meridiem, or after midday.
