[Termite]

Yep I've seen that too in some treated Kapur, the big buggers that reside in Darwin, they'll sacrafice a few to get to the good stuff.

It's the Termite version of the Japanese "Fugu".

I'm getting around to taking a couple of photo's of H4 treated rounds that I'm currently removing showing three posts completely rotted out at ground level (how not to use treated pine). In relation to termites - cca doesn't necessarily kill them, it just makes the timber taste bad. Ive seen treated posts hollowed out, leaving only the outer 10mm where the treatment was most concentrated.

And to our northern friends who speak with a plum in their mouth it's pronounced "Oh Bee"

Funnily enough, I've removed some h4 only put in about 10 years ago that was quite rotted and eaten in the same place - 10 metres away max. The rounds were Koppers, the other H4 was of unknown origin - so I always suspected that it was the quality of the treatment - or more specifically the depth of the treatment. these days it probably comes down to good building practices for timber, especially in bushy areas.

A friend had to demolish a pole home because there was no protection of the bottom of the pole, and they made a run up into the house -no damage to the pole, but it made a great elevator for the little bastards.
