Which of the following pests is commonly found in aquatic environments?

Cattails are wetland plants that thrive in aquatic environments and are not pests in the traditional sense. They are often found growing in shallow waters, marshes, and along the edges of lakes and ponds, providing habitat and food for various wildlife. In the context of integrated pest management and ecology, understanding the role of aquatic plants like cattails is essential, as they can influence the populations and behaviors of other organisms in the ecosystem, including some pest species.

Aphids and scales are insects that primarily infest terrestrial plants and are not typically associated with aquatic environments. Tiger beetles are predatory insects often found in sandy or loose soil habitats rather than in water. Thus, cattails represent the most fitting choice when considering the context of aquatic environments.
