Colony of Red-line Gumtree Hoppers at the base of a ca. 7 year old Yellow Box (approx 10cm trunk diameter). There were also a few individuals and pairs dispersed on a low branch. There were no ants in attendance so it appears the bugs are not feeding, but they must be at least preparing to mate. The male in the second photo is holding onto the female with his middle legs while vibrating his front and backs legs, usually not touching the female. Many pairs in the main group were behaving in a similar way with varying degrees of contact. In one pair the male had his hind legs stationary but was stroking the "face" of the female with his front legs.
This summer has seen a massive cohort or two of Xanthogaleruca luteola, and most elms in the town have been seriously defoliated (except for some of the variegated cultivars). Some nights there are thousands of dead beetles piled up outside lit shop windows, and I've had a steady stream of them inside my house.
Four of these butterflies seen on the same plant. I think this indicates a shortage of daisies rather than a surplus of butterflies. It is a totally degraded paddock except for one small patch of moderately degraded basalt plains grassland with about 20 Calocephalus.
