The rainy period, decreased day-length and the oncoming of Autumn has resulted in many adult orthopteroid insects on the move at night. Here are a few highlights.

Recent extended periods of rain have probably contributed to the large numbers of insects that are coming to our light sheet. The rainy period seems to be responsible for some insect populations to have produced abnormally large numbers of individuals.

The recent rainy period has proved a bonus for the local spider population. It seems there are many more insects about and the spiders are taking advantage.
We found an odd situation. A Golden Orb Weaver (Nephila) had caught a fairly large centipede. How the centipede managed to get into the web is conjecture. The web is placed under our deck and maybe the centipede just made a fatal mistake and fell into it.
This one had caught a small bat. And there are records of this kind of spider netting birds from time to time.

The physical shape of buprestids is easily recognised. But the colour and patterns are extraordinary in their variability. The authors state in the Preface that the book is "intended to be an introduction to the interrelationships and diversity of Australia's spectacular buprestid fauna, from which we trust will follow a greater concern for the fauna's conservation, and that of the landscapes and plant communities in which buprestids dwell and interact." It will do more than that and may stimulate an interest in both collecting and photographing these living Australian gems.
Both buprestid larvae and adults are plant feeders. The larvae have a distinctive shape are often found under bark where they feed on plant tissue. The adults are usually found feeding in flowers on sunny days. A small number of adults have nocturnal habits.
The book has sections on fossil history, Gondawanan and extra-continental associations, warning colours and defence and predators.
The excellently reproduced colour plates are in three sections. "Beetle Specimens, Live Beetles, Regional buprestid faunas and habitats.
The photographs in the Live Beetles section were done by Kevin Mitchell who utilised "stacked focus" to achieve the terrific results.
The "Live Beetles" section shows some of the beetles in nature. The splendid photographs were taken mostly by Geoff Williams and Alan Sundholm.
