This solitary gall was about 20 mm long, arising straight out of and at an acute angle to a narrow branch. The gall appeared to have shallow grooves running through the length of it. The free end appeared to taper with a slight bulge to the portion immediately below it.


Spotted on a young eucalyptus tree - species unknown . Cardinia Reservoir Park.


This gall was induced by a scale insect of the family Eriococcidae. Pics 3 to 6 added on 12 May 2015. Slight increase in girth of gall .

That'd be great. If it's not a red gum, it might be an undescribed species of Apiomorpha!

l.cook, I am not quite sure what of the species of tree. It was young with slightly broad leaves with ? fungal spots. Foliage was scanty. Unfortunately, I did not take any shots of the tree but I might be able to find it again and get some pics. Thank you for your comments.

Great find Leuba. Any chance the host was a red gum of some sort?
