Dasineura furcata
These galls were seen on an Australian Blackwood (Acacia melanoxylon) tree. The galls varied in size, the largest being the size of a walnut. The gall appeared to have multiple locules elongated and twisted, each tubular locule had a small opening at its end.
Riparian zone at a local retarding basin.
The galls were found at the end of primary stems. I could not see any other sign of insect life on the tree, except what looked like an egg case with holes in it ( pic #5). This was at the tip of a cladode. This gall is said to be caused by a midge. I need to look further for more information. Thanks to PenelopeMills2 for correcting the original ID and thanks to Mark Ridgway for his help. Finally I got the correct ID from Dr. Lyn Cook. My thanks to her for the help. https://onlinelibrary.wiley.com/doi/pdf/...
Thank you so much for looking at this spotting and for the information, PenelopeMills2. I am always hoping that someone with expertise would look at galls on PN an correct or suggest an ID. I will have to revisit my reference to see where I've gone wrong. Thanks again for your input - have learnt something today !!
Will check Mark Ridgway's suggestion.
These galls do not appear to be male galls of Apiomorpha - Apiomorpha is host-specific to Eucalyptus.
These are perhaps cladodes ( modified stems) that have been deformed by thrip infestation??
Well that's a fine example of making chaos out of order. What a blob! There must be some interesting stories behind these things.
