Lovely large ladies on the alpine mintbush! Both these insects are big, for bugs, and both are flightless, flashy coloured, and female.

On the right is the spotted mountain grasshopper (Monistria concinna), who’s delightful spots are an aposematic colouration warning of her toxicity. She’s grazing voraciously on the mintbush to build up weight before winter, where she won’t die like other alpine insects but rather, she will freeze solid, awaiting the thaw of spring to live and eat another year!

On the left, the flagship species of my lab, the mountain katydid (Acripeza reticulata), doing her deimatic display. She has lifted her wing cases to reveal her colourful, curled abdomen covered in foul tasting secretions, as well as inflating her orange throat patches. She too is eating the mintbush, possibly to sequester the toxins in its leaves for her defense, like the grasshopper does.

These gorgeous girls are but a small part of the fantastic array of Australian alpine invertebrates that make fieldwork a real treat.
