The flies buzzing around this depiction of the Helicodiceros muscivorus flower are no joke — they are part of any encounter. Its name is also apt, as the stench smells like rotting dead horse. Of course, the smell attracts flies, which in turn act as pollinators. You wouldn't want to find yourself lost in a field of these flowers on a beautiful day. Interestingly, the spathe won't unroll if the day is cloudy. It waits for a clear, sunny day so that the smell can spread far and wide.
