The line about the crickets was the reference to this:
Spinochordodes tellinii is a parasit <...> whose larvae develop in grasshoppers and crickets. This parasite is able to influence its host's behavior: once the parasite is grown, it causes its grasshopper host to jump into water, where the grasshopper will likely drown.
