I have a new queen. Lasius brevicornis. The queen is about 9mm Her nanitics are so tiny I'm going to cry. They are 1.5mm and transparent yellow.

They are smaller than the antennae on my Camponotus pennsylvanicus queen. Nanitics are the first workers in a colony and they are often smaller than the workers produced later when the colony is better established. But this is out of control. They are just so small.

They would make a fruit fly look like an elephant.

They still have six legs, tiny mandibles and tiny ant intentions and projects they are working on with their mother.

What do they have in their legs? One muscle fiber per joint?

They are so complex and tiny it's breaking my brain a little.

I don't understand why people aren't freaked about about this more often.

@futurebird Insect brains seem like a very obvious place to start when studying intelligence - the fact that a few hundred thousand neurons can manifest such a widely varied responsiveness to their environment could tell us a lot about how to build machines that work effectively.

@emeb

They dig and maintain the nest.
They forage for food and lay trails.
They defend each other and the queen from threats.
They find and farm scale insects for nectar.
They stop and greet each other and check if anyone who wants to enter is from the colony.

So much complexity and you have one of the smallest ant brains. They do vary in size a lot, and ants have relatively large brains for their size as insects (bees do too)

But when you look at the smallest ants it's kind of shocking.

@futurebird @emeb based on this diagram, I conjecture that brain size is a limiting factor in ant miniaturization.

@llewelly @emeb

You know they'd have ants small enough to manipulate cells if they could get away with it. The tiny nurse ants do work on the hyphae of fungi that's like delicate surgery as it is.
