Once the weevils have pupated, they chew small holes through the side of the stem to exit the pupation chamber as fully formed adults (Figure 3). It’s easy to see why this emersed aquatic plant is called parrot feather. [1] Aiken, S.G. (1981). Due to the waxy cuticle of the emergent leaves and stems which repels many herbicides, a surfactant mixed with the herbicide may be required that can penetrate this cuticle. Influence of Myriophyllum aquaticum cover on Anopheles mosquito abundance, oviposition, and larval microhabitat. Natural control of parrot’s feather through insects such as Lysanthia flavipes and Listronotus marginicollis are known to damage the plant in its native range and have had some success in South America.
