Walking the Summit Track on Saturday I saw this extraordinary looking growth on the underside a branch high up in a Spotted Gum Corymbia citriodra.

Spotted Gums grow to 45m so this photo was taken at about x60 digital zoom on my Canon SX20. So viewing the photo later it looked like some sort of sculpture made of concrete and hung on a tree 30 or 40 metres in the air.

My excellent network of experts came to my rescue suggesting a wasp nest. Some more research on Google gave me the answer: Yellow Paper Wasp Ropalidia romandi . Links:  Queensland Museum Fact Sheet and Queensland Naturalists Club article.

I have photographed Yellow Paper Wasp for Flora & Fauna of Mt Gravatt Reserve however I did not realise that this tiny wasp: at 6-8mm it is the smallest of our local paper wasps, builds these huge paper nests. Up to 1 metre long these amazing sculptures are made up of multiple paper combs all wrapped in a paper skin.

I found this nest while researching our new self-guided Summit Track tail brochure. If you are walking the Summit track stop at Station 6 and look west-north-west for a large Spotted Gum then follow the trunk up to the branch growing out to the right. The nest looks like a concrete sculpture hanging under the branch.

Our new trail guide will be available early August ready for the Environmental & Photography Workshops. The guide will also be available online and copies available at a local BCC Library.
