Funny story - I went to tease my local Camponotus nigriceps colony at a nearby bush trail, and spotted a winged ant 1 feet below.
Then saw more and some Polyrachis with a silver bum.
They look to be getting ready to fly. Was around 4 pm in Sydney, north side. Might be Polyrachis daemeli
Then a few spider ant workers (Leptomyrmex) walked by, and then saw a R.metallica drag a semi dead Poly alate away
