Hi, firstly we don't know anything about this field and hope you don't mind but is it possible that this is Chaetedus longiceps a member of Plant Bugs Family (Miridae). This was the ID given on iNaturalist by a person whose main interest is bugs of Australia. I had suggested it as Mutusca Brevicornus first after the ID given on here, thank you. His reasons were as follows: "Actually even a different superfamily. Similar at first glance and a trained eye is needed to tell them apart, as the slender body of both species is an adaptation to living on grasses." the link to the sighting on iNat is https://inaturalist.ala.org.au/observations/176740619#activity_identification_ec2bfa55-68e5-4262-8dc2-037cc684e907 Hope this is okay, just trying to help, it may be a new species here for CNM. Thank you very much for your time and help it is greatly appreciated.
