So i artificially hatched a camponautus worker since the queen was ignoring her. After reintroduction, the queen attacked the worker. Anyone know why.

Guessing but maybe it just didn't smell like the rest or Something is wrong with it that she can sense and that is why she ignored it in the first place?

New workers, known as Callows, haven’t fully adopted the colony scent when they hatch. This makes them very useful for raising parasitic species.

The queen probably smelled human pheromones.... :D

Not entirely sure what you mean by "artificially hatched," but the cuticular hydrocarbons responsible for colony scent identification may have been modified by your handling or time away from the nest.  If so, the colony may reject the ant based on its unfamiliar odor, in the same way that a small rodent mother may rejects babies that have been handled by people.

You very carefully snip the pupa open without harming the worker inside, and gently squeeze the other end of the pupa, and the worker should slide right out (or at least that's how I did it. :D )

I poked a hole with a needle  in between the hollow between the thorax and gaster, and then pulled the needle up to make a tab. Then I pulled the tab up.

Sounds like something I would fail pretty bad at... Directions unclear, snipped ant in half
I don't think I could ever attempt anything like this

So, the same speicies of ant had a worker curl up into a pupae position and is now being treated like a pupae. what's going on? The worker never made a cocoon, does that have to do with it?
