There were large numbers of these very small beetles on the Myoporum insulare on Providence Road adjacent to Woodlands Historic Park. (These were planted by the council and do not occur in the Park.) I believe the enlarged hind tibia identifies it as a flea beetle, tribe Alticini, which narrows it down to one of 232 species according to AFD
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.
Seems to be feeding on a Yellow Box leaf. After wading through 500+ Pentatomidae photos on Bowerbird the only match I could find was http://www.bowerbird.org.au/observations/88269. According to the post Acanthosomatidae differs from Pentatomidae in having 2 instead of 3 tarsal segments but I don't think you can see that in my crappy photo.
Larval food plants are in the citrus family and do not exist in the park. I have previously seen the species mating at the Gellibrand Hill summit, and I assume this one next to Providence Road was there for the same purpose. I may have seen one in exactly the same spot last year. Presumably it is the closest place to someones Lemon tree that matches the criteria for a mating site.
In the vegie patch at the Woodlands Historic Park office. Larval food plants in the Urticaceae family - the only extant plant in the park is the weed Small Nettle. Not sure what was of interest in the vegie patch, don't think they are growing any nettles.
large wasp, about 20mm long. Looks similar to photos of Gotra sp. on bowerbird except mine seems to have orange on the abdomen while all the others are black and white only. Also mine has a rather short ovipositor.
Separate photos of fruit and leaf. This is the first record of the species at Woodlands Historic Park. Probably the last record too since I only found two plants, surrounded by several million *Plantago lanceolata (rough estimate!).
Another Gumtree hopper seen last summer on Eucalyptus melliodora but not this summer. I have said genus Eurymeloides due to the two rows of spurs on the hind tibia (see third photo), but does not match any species pictures I can find.
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.
On small Yellow Box (coppice regrowth). Many adults (mostly paired) and nymphs on same tree and another nearby. Closest photographic match I have found on the web is Eurymelops rubrovittata, but this seems to be a different species. Host trees will probably be slashed by Parks Victoria soon as in previous two years.
Update: I have added another photo which shows the markings on what I assume to be the female. Since these match other photos on the web (including museum specimens on ala) I have changed the species to Eurymelops rubrovittata.
A very confusing photo of some stem galls on a young (about 1m high) Yellow Box, one branch of which was almost completely covered in galls. The red is obviously a gall, but the green blades that look like leaves are parts of another type of gall. Of course there are the usual attending ants, but then if you look closer there are orange dots which are perhaps eggs of some kind, and what look like early stage Hemiptera nymphs. Are these nymphs associated with the gall in same way, and if so how? If they are a gall forming species shouldn't they emerge as adults? Wish I had the equipment to be able to watch what is going on for a few days.
