After hot water maceration didn't produce quite the result I expected, I decided to drain the remains, leave them outside and let nature take its course.
I read that dermestid beetles are one of the best and most thorough way to render a corpse down to a skeleton, and I've always been extremely interested in growing a colony of my own.
Unfortunately, I cant access them locally and I'm a little apprehensive about ordering them online. May have to done a bit more research.
So with no dermestid beetles readily available, I left the bones open to any insects willing to have them.
Fortunately they attracted a bunch of very keen ants.
They cleaned the bones wonderfully! I left them out for around two week undercover and the little critters really polished them up nicely.
A lesson I learnt for next time was to cover the container a little more. Didn't really enjoy picking through the dirt and leaves, and it runs the risk of damaging the bones.
It seemed it wasn't just the black ants that were interested in the bones (or maybe it was just the area they were in).
A colony of green ants were nearby and on the offensive. I couldn't resist capturing the action in a heated battle field. Green ants are an extremely aggressive specices. I know from personal experience that even a single ant, if aggravated, will vow a personal vendetta on you (man or beast) and will not stop until vengeance is done!
