Thanks Matt.. Intersting, because sheeps Burr, Acaena sp., is one of the food palnts recorded for Keyacris, although my own view is that they are polyphagous.
Today I drove out along the Yaouk Road from Shannons Flat and stopped at a number of likely looking habitat patches for Keyacris but did not see any, although I missed the access road to your site as shown on the above map. Can you provide any details of how I get to this area as I assume its on private property. Thanks Roger
