Hi, these bugs really stink. There are hundreds of them around at the moment. They seem to detect you and head straight for you. If they get on you and you flick them off they leave a horrible stink behind. I have tried to find out what they are called and info about them but have had no luck .
This is a Ground Beetle in the family Carabidae. It appears to be a Caterpillar Hunter in the genus Calosoma, and it might be Calosoma oceanicum, which accoring to the Calosoma of the World website is found in Australia. As with most creatures, populations spike when there is a ready food supply, and perhaps conditions have produced an abundance of Caterpillars this year that can support the Caterpillar Hunter population.
