    Paropsisterna semifumata. This small beetle is a riparian species and feeds only on white Callistemon spp.? growing in creeks and rivers along the eastern coast of Australia up to Brisbane. I've seen it both times that I've looked at this reserve but its probably common enough along Jacksons Creek wherever you find Callistemon. Semi + fumata translates in Latin to half + smokey.

    1. Mark Ridgway  Special find. You must be near to name one yourself.

    Walking through forest at Lerderderg Gorge, this beetle found its way on to Lydia (age 11) so no idea which plant it was on originally.

    1. Martin Lagerwey  This beetle is Paropsisterna semifumata (= half + smoky) . They are riparian and feed on the white callistemon foliage that grow in creeks. Nice find

      • Russell Best  Thanks Martin. This was a riparian find, being alongside the Lerderderg River. There would have been plenty of the white-flowering Callistemon sieberi at this location too.

        • Martin Lagerwey  It is fascinating to consider the dependency of monophagus insects on their host plants along with the plant distribution. This dependency is most extreme among Chrysomelidae (also Hemiptera and probably Hymenoptera). I find this beetle reliably at Organ Pipes NP on Jacksons Creek and you have named the C. sieberi correctly. I found the same beetle at Licola in the Macalister River on the same plant and am aware of sightings in Sydney and Brisbane. The huge number of species of beetles (350,000 species) is contributed in no small part to the speciation of their host plants.
