Calling Entomologists: Sap Tunnel

I saw this unusal structure whilst walking through Namadgi National Park.

It is a tunnel formed from hundreds of balls made with sap. It was found on the branch of a Snow Gum (Eucalyptus pauciflora). There appeared to be some sort of insect living inside it.

If you know what it is, I would love to know. Please post in the Comments below.


  1. Did you ever find out what it was?

  2. Hi Amanda,

    Afraid not! I am going to ask some people up at CSIRO if I get the chance.
