context_page_description: Henicopsaltria eydouxii, commonly known as the razor grinder, is a large species of cicada native to eastern Australia. Predominantly brown in colour, it is found in dry and wet sclerophyll forest in December and January and is quite common in Brisbane.
context_section_description: Male razor grinders sing in large groups on the main trunks of tall eucalypts, especially spotted gum (Corymbia maculata). In some years their numbers can be locally immense, but in other years very few adults emerge.
  Adult razor grinders are wary and flighty, especially at dusk, and are difficult to approach. They are fast flyers.
