So apparently i own some ants

[antking]

Hey all,

I've been building a bee hotel and accidentally stumbled upon a small ants nest inside a piece of bamboo. They've since migrated into my little hotel and are enjoying their new life. I'm in Sydney, Australia.

Anyway, the colony is about ~20 or 30 strong, has at least a dozen brood (accidentally knocked them onto the ground when i found them, but they all got collected and are safe), and i think has a queen in there too. All the ants are housed inside the end of a piece of bamboo, and they accept my offerings of blueberries / strawberries happily.

Can you help me figure out what species they are?

okay not entirely sure, but i think its either formica or camponotus

Almost certain is Polyrhachis sp. I'm gonna guess P. ammon. Very lucky man. Hope it helps!
