It does, but the internal regions were not dehydrated, yes? Therefore, the process of decomposition was not delayed there. And that's where the bugs were.
The body wasn't desiccated, Kimmy. They recovered some 180ml of fluid from the lung cavity IIRC. Unless they stuck her body in a drying oven and weighed her before and after, there is no telling how much moisture was still available.
Hands, foot, ears. Low fat/low water mass. those will mummify quickly.
The odd thing is no (or very few) insects in the braincase, It should have been infested with maggots but it wasn't.
And nobody has testified that the brain was mummified or dryed-out.
