Last December and January these little flies visited our place where they sat on our Eucalyptus citriodora tree to cool down. This week we found them sitting head toward the ground on Xanthorrhoea fronds during the cooler part of the day toward evening. We found up to 7 on one grasstree. The female is larger than the male by a few mm and has a white end to her abdomen.~4-5mmFemale: www.flickr.com/photos/jean_hort/5265054506/ Male: www.flickr.com/photos/jean_hort/5403906970/ Fred had to hold the fronds to stop them swaying. Thanks Fred.
