Obloid larvae


My Acacia mearnsii (Black wattle) died recently. It seems to have been hollowed out by some beetle larvae. They are obloid when small (15mm) but get cylindrical when larger (25mm).


Suburban back yard. A common local tree that appears throughout our forests.


This species of acacia seems very vulnerable to many pests. They die suddenly and fall easily spreading their seed when they crash down. I often find a patch of thousands of new seedlings in the forest where an old tree has collapsed and I'm entertaining a theory that this is a strategy for reproduction.
I am guessing mostly likely beetles possibly longicorn borers (Cerambycidae)
No luck with likely species yet...
