From the reference this Lacewing species is not uncommon but we only saw them once. It was late May, early winter in Eight Mile Plains. We saw about ten of them resting about 2 to 3 meter from ground on two gum tree trunks. Some of them were resting facing each others. We watched for a few minutes and they were not doing anything. Only flied away when we were almost touching them.

We came back to the two gum trees the next week, and found that they were still there. Still facing each other in pair, doing nothing.
