Grasshoppers’ terror outlives them

Carcasses of jumpy insects taint soil

Terrified insects can haunt their homeland after they die. Chemical remnants of fear in the rotting corpses of grasshoppers slow the decomposition of dead grass and other debris important for fertilizing new plant growth, a new study finds.

Fear can change the chemical composition of the grasshopper Melanoplus femurrubrum such that later on its corpse slows the decomposition of plants by soil microbes.
