Eucalyptus Weevil

Gonipterus spp.

Description:

A small grub (approx 15mm) pale cream/green semi-translucent body, dark line visible within body, black looping string attached up to 160mm long of dried faecal matter.

Habitat:

Dry sclerophyll eucalyptus forest.

Notes:

?Gonipterus scutellatus (Gyllenhal) The strings were varying lengths (80-160mm) but present on all 30 (approx) of these creatures found. Not a problem in Australia but often where Eucalyptus has been taken overseas it can be a pest. Adult version here http://www.projectnoah.org/spottings/167...

If it is, it's called frass.

Yes ArgyBee, I too thought it's probably excreted waste products; the coils are not formed to a pattern and, they look very dry !! .Here's confirmation.....

So right martinl - we walked only 200 metres into the local state forest with cameras this morning and I will need to spend days on this website as a result.
Can't wait to try a National Park or two.
These 'strings' were really quite tough btw... like wires.

Well there goes my theory, CXW's guess looks more likely. Nature always has another surprise.

Thanks CXW - how common is it?
I thought this might possibly be a decoy plan for potential predators.

Many insect keep their feces and other excrement on their body.
Seems like this is one of them.

Hi martinl. I thought you might like these. Thanks for the thoughts however bizarre. These guys were very much alive so if your fungus theory is true it hasn't killed them yet. Interesting eh!

How bizarre! The larvae are leaf beetle, therefore technically a grub and not a caterpillar. My wild guess is a fungus that eats the insect tissue from inside and then grows a spore producing body, like a fruit.
