I wrote recently about the honey-producing native bees and, a little longer ago, about the Blue-banded bees which have been so numerous in my garden recently, but there are many others. Wandering around the garden of the house on Hervey’s Range last week I spotted an hibiscus flower with an insect deep in its throat. All that was visible was a furry golden abdomen. I waited and was able to catch a shot as it reversed out:
It flew on and nose-dived into the next flower, so it obviously thought it was onto a good thing.
I looked it up later. It seems likely to be Amegilla aeruginosa, also known as Notomegilla aeruginosa (Apidae: Apinae: Anthophorini). Its colour is somewhat greenish when seen away from the intense red of the flower.
Bees in this family (Anthophorini) are solitary and usually make nests in the ground; most of them are quite large but have disproportionately small wings. My Blue-banded bee, another Amegilla species, is also a member of the family.
Still no rain* – at all** – and any area which doesn’t get watered by people is tinder dry or has already gone up in flames. People in one of our outer southern suburbs were under evacuation warning earlier this week but fortunately the threat was averted. We had a couple of days in the mid-thirties a couple of weeks ago, and then temperatures dropped again for a while but they are back up now and many of us suspect they are going to stay up – meaning daily highs of 32 – 36C and overnight lows around 20C. Humidity is up a little, too.
With all that, we are seeing a wider variety of insect life in the garden but not much increase in absolute numbers. Amongst the butterflies, Lemon Migrants, Ulysses, Orchard Swallowtail, Clearwing Swallowtail and Pale Triangle have joined Cairns Birdwings as frequent visitors, and all our recent residents – Chocolate Soldier, Crow and Eggfly – are still around (although still mostly male Eggfly; I have only seen one female). There are still Magpie Moths and the little grass moths, and a few more Hesperidae than we have been seeing.
Of the wasps and bees, the success stories are ichneumonid wasps, colourful mid-size to small critters with unpleasant baby-feeding habits, and my Blue-bum Bee, Amegilla. Of the flies, hover-flies still rule but there are lots of others as well; and I saw a Crane-fly pogo-ing around laying eggs in the soft dirt recently. Dragonflies have been returning intermittently and we have seen some of the smaller grasshopper species, a mating pair of giant grasshoppers, some ladybirds and a few shield bugs and pod-sucking bugs. Also, I’m less happy to report, a noticeable build-up of mozzie numbers. Oh well, the wonderful winter makes up for the less-wonderful summer.
I’ve been tracking spider numbers after a conversation with a southerner about the best time for a collecting trip up here in relation to our Wet/Dry seasons, and it’s looking tricky: we have had hardly any of the orb-weavers for a couple of months now but in the last few weeks I have been seeing lots of little ambush predators – Lynx and Flower Spiders (1, 2)in particular.
Qld September is even more impressive: Townsville is just on the edge of the white 0 – 1 mm area.
** Until after I finished writing the above. Let history record that on the evening of October 14, we had our first rain in six weeks and a pretty good thunderstorm. But I’m not going to rewrite my blog post!!
