Here are a couple of photos of the insect seen laying eggs in the video a while ago. I believe it's a Crane Fly, and there is one like it on page 117 of "Wings - an introduction to Tasmania's winged insects" by Elizabeth and Anthony Daley. This is labelled Ischnotoma sp. The insect was injured, possibly by the cat who loves to chase moving things. My son found it and thought it was an interesting insect and as we watched it, we could see it laying eggs. Hence the video in the earlier blog post.
