Helicodiceros muscivorus, the dead horse arum lily,[2][3] is an ornamental plant native to Corsica, Sardinia and the Balearic Islands.

The flowers of H. muscivorus smell like rotting meat, attracting carrion-seeking blow flies which act as pollinators.

One of a rare group of thermogenic plants, the dead horse arum can raise its temperature by thermogenesis.

In between is a hairy spathe such as a ‘tail’ running down into the chamber of the flower which bonds with the fertile male and female florets.

The exits of the female florets are hindered by spines and filaments which serve to trap the blow flies once inside.

[10] The dead horse arum manipulates the heat to release an odor that lures the flies to the structure of the appendix of the flower to begin pollination.

(This source should not be cited to describe the specific interaction between these two species)[11] The thermogeny has a direct effect on the pollinators, by altering their behavior.

Although male florets of the dead horse arum exhibit some independence from ambient temperature the pattern has shown that heat production depends on time of the day.
