resurrected roaches

There is a new companion in my life.

Two days ago, I stepped on a cockroach in my bathroom. She gave a flat kind of crack and yellow-green paste came out of the sides of her abdomen. After a few minutes, she started twitching feebly, so I left her and got on with my life.
The next day, in the morning, she was gone. I though nothing of it until I found her in the corner, on her back, legs curled up. She sensed me looking at her, and twitched her legs and waved her antennae. I ignored her again.
Tonight, she was still on her back... but, now on the other side of the room. When I switched on the light, there were some smaller 'roaches around her, and they scurried off. What did you think... they were giving her get-well-soon cards? The intestinal loops and solidifying paste she had been dragging around the last 48 hours were gone. They had been eating her alive, in the dark.

A cockroach lives 2 years, a human seventy. A human will die without water in three days. This is around 0.0117% of his life. By that logic, a cockroach should die in 2.06 hours without water. This one has been twitching happily for close to 72 hours now.

Great. The assorted ecology of my apartment can now be expanded to include an undead cockroach.

I shall call her Mallika.
