"They are sometimes found dead in swimming pools and ponded waters. This is either the result of a simple drowning or a parasite infection. The horsehair worm (
Gordius or
Paragordius spp.) can inhabit the cricket's gut and feed. The worm can alter the behavior of the cricket and force it to seek water. Once in water, the worm bursts through the insect's abdomen and seeks a mate. The cricket dies from the wound." (
