Note characteristic feeding scars.Alligatorweed is an aquatic weed native to South America that began threatening Florida’s waterways in the early 1900s. Alligatorweed flea beetles kill the plant by destroying its stored food and interfering with photosynthesis by removing leaf tissue. This insect has been an extremely effective biological control agent in coastal regions of the southeastern United States. This 3-page fact sheet was written by Ted D. Center, James P.
