Field Notes

Description:

Very flat (similar to some cockroaches) and about 24mm long. This species has tubercules on elytra. Black with tan colouring at margins. Beaded antennae with distinctive yellow tips.

Habitat:

This one was attracted to very bright night lights at a local used car yard.

Notes:

Apparently these rest by day in shaded places and become active at night. They seek out carrion by scent. To assist in their activities around a corpse they are gifted with a flexible abdomen. Described as 'vultures' of the beetle world it's a rotten job but something has to do it. Although they perform a grizzly task they represent no threat to human health. Thanks to Stephen Thorpe for identity. The same species seen 18 months earlier http://www.projectnoah.org/spottings/8077680

Welcome, Mark! I always was a louzy football kicker, but I still have good eyes to kick you on and sometimes we need these additional challenges ;-)...
Thanks for kicking us on bayucca. Your 'inverts sense' is in good working order. :)
Thanks Lauren. Great work to get to Silphids. You got it in Flickr. I think I would have been bashing my head on a brick wall until I had more lumps than this beetle.

Looks like this Silphid.... http://www.flickr.com/photos/25401497@N02/4528899813/lightbox/
Uh oh... thanks so much Stephen. I was looking in all the wrong places. This should be a good read.
Wow. Bayucca made me look closer too. Could it be one of those weird flat Silphids? The tarsi and antennae kind of fit.
Thanks bayucca. I will look at this again from square one. Leuba had one 18 months ago (when we were even greener) so we need to re-check old notes. Stay tuned...
Looking at yours and compare with Helea sp. I am a little bit confused. Not that I dare to challenge your ID from far away, but I am sceptic about the genus. I did not find any matching Lampyridae, that was my first sight guess... http://australianmuseum.net.au/Pie-dish-Beetles http://www.flickr.com/photos/centralaustralia/3181936522/ What do you think?
