Hard to believe but those become these!

found these while shifting some redgum slabs which were once riddled with the larvae looks like they got sick of eating drying redgum and have been turning into the adult form.

They are another variety of longicorn beetle similar to the ones i just posted a pic of. will eat right through a large river redgum and they infest en masse and weeken large limbs to the point where they will just drop off. I have never seen them in casuarinas or any other "softwood species" but almost every type of eucalypt I have cut has had them nibbling away at them.

What about this little critter?



not the best pic - from the mobile, but I'm sure you get the idea

I've seen them before, not often though.

Sigidi is that beetle maroony and does it have a really hard shell? If so then they're the same ones I found in the pipe of a blue gum mingling with some termites.

FC they are a red/brown seem to have a hard shiny body, got some wicked lookin pincers!! Looks like they could just melt through timber

I had some of those red/brown beetles in some mackay cedar, the borers where voracious holes in sapwood everywhere, u could hear them chewing and they left great piles of fras
Pete

yep thats longhorn beetles for ya. after I built my redgum table I could sit out there and listen to them chewing away
