Phalacrognathus muelleri has been the official symbol of the Entomological Society of Queensland since 1973.

[3][4] In 1885 the species was named Phalacrognathus muelleri by Sir William Macleay in honour of Baron Ferdinand von Mueller, the Victorian Government Botanist.

Males of Phalacrognathus muelleri are the largest members of the family Lucanidae in Australia.

[1] their beautiful colours fade after death and are difficult to photograph.
