This hawk moth (most likely a Violet Gliding Hawk Moth (Ambulyx liturata, Sphingidae)) has been parasitized by an Akanthomyces fungus (probably Akanthomyces pistillariiformis), a Cordyceps anamorph peculiar to moths.

After killing the moth, the fungus then totally engulfs and embalms the corpse producing this macabre sight. (An entomopathogenic fungus is a fungus that can act as a parasite of insects and kills or seriously disables them.)

Cordyceps fungi is a common ingredient in Chinese herbal
medicines. In general, mushrooms wouldn’t seem like an obscure
ingredient, however, this particular mushroom grows from the bodies of
insects. If a spore lands on an insect, it can infect it. The fungus
then grows within the body, using the internal organs as a food source.
Eventually, the fungus rips out of the insect, distributing more spores.
