While playing on their fort today, the children called out to me, asking me to come and have a look at the "fury grubs" on the Iron Bark Tree. After climbing up the fort - they showed me their discovery. A large group of Larva, of unknown species. The cluster reminded me instantly of the Paperback Sawfly Lava that we have often seen here, an the way they often cluster together, but this one was different and not the Paperback Sawfly. Any ideas anyone? A most spectacular find by the kids.
