Claim: The entomophaga grylli is a species complex (a group of closely related organisms that are so similar in appearance) that are helpful in the growth of several insects.
Evidence: Entomophaga grylli is a fungal pathogen which infects and kills grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores. The pathogen has potential for biological control of grasshoppers but more research is needed.
