Hi Jenni, there are two types of ants in your photos. The first photo is of a Camponotus (IDed as Camponotus sp.) and the second photo is of an Iridomyrmex (IDed as Iridomyrmex rufoniger). Can you turn them into seperate sightings? Cheers, Jon. And, by the way, I like the way that the flower in your second photo is clapping its hands!
