Discovery Bay Coastal Park

29 November 2014

I returned to the swamps in Discovery Bay Coastal Park, partly for the recently rediscovered Micraspis flavovittata ladybird. This time I found few adult beetles but quite a lot of larvae, which are probably of this species.

There were also these beetles present. I first saw these in 6 years earlier but at the time only got a couple of low-resolution images with an older camera. Apparently the females of this beetle family live almost their entire life underground, only nearing the surface to mate. I observed a few males flying around in circles low to the ground before landing, then foraging around briefly before digging out the females and mating with them. The local bullants (possibly Myrmecia gulosa) seemed to be aware of the situation and I observed one interested in the sandy ground when I inadvertently scared it away. A few seconds later a male beetle landed there, dug out the female and mating took place. After mating, which took around one minute, the female buried herself again and the male flew off in search for more females. I also observed several of the bullants carting off some beetles, possibly all females (which they would have subdued).
