Description: Bull ants, also know as bulldog ants (you can guess why), are primitive ants of the genus Myrmecia. They are aggressive, carnivorous, and to top it all off, they possess a painful, venomous stinger on the tip of their abdomen. Needless to say, these aren't your average picnic ants. They are endemic (only found in) Australia, so they are of special interest to me! I found this particular ant while hiking out in New South Wales' Blue Mountains.
