I think it might be Campion sp., but I have never attempted an ID on a mantis fly before. ID assistance would be greatly appreciated. Three photos uploaded including face and top down view. Campion tenuistrigus ID by Ken Harris via BowerBird.
Scarlet Honeyeaters have irrupted into Victoria this spring, and have been recorded in many places that they have never been seen in before. It was great to find two at my local patch, which is probably not the right habitat for these at all. Wikipedia has an interesting article on irruption https://en.m.wikipedia.org/wiki/Irruptive_growth
I drove to Newstead this afetrnoon to see the pair of Barking Owls that have been reported recently. They have been heavily twitched all week. I haven't given the exact location for these as they are quite rare and endangered in Victoria, although it's becoming fairly common knowledge amongst birders. It appears to be regurgitating a pellet.
