The total rainfall since my previous mid-month summary is exactly zero, and the relative humidity has been very low, too: below 20% at 3pm every day for the last two weeks, for instance. Temperatures have consistently swung between 8 – 10C overnight and the mid twenties during the day. Cool and dry is not what the bugs like and I’m beginning to think of them as being in ‘maintenance mode’, just ticking over and waiting for some warmth and moisture.
The paperbark is flowering, as I mentioned a few days ago, and so is the mango tree. The Macadamia is almost ready to follow suit, and so is the Poplar Gum. Each of these trees attracts its own group of nectar-feeders. The birds love the paperbark (as I mentioned in my previous post) and the poplar gum, but are not particularly fond of the other two. The honey bees don’t seem to care for the mango blossom but love the other three, so that pretty much leaves the mango to the butterflies, the flies (mainly hoverflies), wasps and native bees.
I’m seeing …
- Quite a lot of little orb-weaving spiders – Silver Orb-weavers (Leucauge granulata), Spiny Orb-weavers ( which I now believe to be Gasteracantha sacerdotalis rather than Austracantha) and St Andrew’s Cross spiders; also quite a lot of jumping spiders (Salticidae), some Lynx, and a few flower spiders.
- Hoppers and their nymphs, which often become food for the above.
- Butterflies: reasonable numbers of Junonia and Eurema and grass moths; very small numbers of everything else but including Migrants, Skippers, Melanitis leda and recently one visiting Orchard Swallowtail.
- Diptera (Flies): Long-legged flies (see bottom of this page), Hoverflies (see at left) and Blowflies, with occasional soldier flies and craneflies (above) and – still – mosquitoes.
- Hymenoptera (wasps, bees and ants): occasional little wasps including paper wasps (though no nests that I’m aware of) and a very few mud-daubers; some native bees again recently after a gap of a few months; the usual small ants and a slowly-growing green-ant colony.
- Others: a few Giant Grasshoppers; a healthy population of cockroaches in the compost bin; but no mantises (although saying that usually ensures I will see one in the next day or so).
Same time a year ago
