2014 $1 Bright Bugs Leichhardt's Grasshopper Coloured Frosted Uncirculated Coin. 

The Leichhardt's Grasshopper is one of Australia's most spectacular grasshoppers and a Kakadu Icon.

These colourful insects are named after the explorer Ludwig Leichhardt, who reported great numbers of them as he travelled through the Deaf Adder Creek area, which runs off the South Alligator River on the Northern Territory’s Arnhem Land plateau in 1845.

They are only found in a few places – Kakadu, West Arnhem Land, Nitmiluk National Park, and Keep River National Park on the Northern Territory’s western border where shrubs of the genus Pityrodia grow. The grasshoppers are very fond of eating the Pityrodia plant that they will remain on a single shrub for life. 

Leichhardt’s grasshoppers scare off potential predators with a chemical defence. When the insects feel threatened, they secrete a smelly brown substance that tastes awful to any animals looking for a snack.

The grasshopper's indigenous name is Alyurr, which means children of the lightning man Namarrgon, who are called to bring on the monsoon at the end of the dry season. Mintage 30,000.
