Few garden discoveries create as much surprise as finding what appears to be a long, animated strand of horsehair twisting through a bird bath, rain barrel, pet water dish, or puddle.

What Is a Horsehair Worm?<\/strong><\/p>\n\n\n\n

Horsehair worms belong to a group of animals called Nematomorpha<\/em>. Adults resemble thin strands of brown, black, or tan fishing line or horsehair and typically measure 8 to 14 inches (20\u201335 cm) long while being only about 1 millimeter thick.<\/p>\n\n\n\n
