See here Cabomba caroliniana, commonly known as Carolina fanwort,[3] is a rhizomatous,[4] aquatic,[5] perennial,[3] herb[5] native to North and South America.

[15] It is native to southeastern South America (southern Brazil, Paraguay, Uruguay, and northeastern Argentina),[16] and the East and West Coasts of the United States.

[citation needed] This species grows rooted in the mud of stagnant to slow-flowing water, including streams, smaller rivers, lakes, ponds, sloughs, and ditches.

Fanwort stems become brittle in late summer, which causes the plant to break apart, facilitating its distribution and invasion of new water bodies.

[17] Use in the aquarium trade has led to some species being introduced to other parts of the world, such as Australia, where Cabomba caroliniana it is a nationally declared weed.

[8] Having arrived in 1967, it spread rapidly in waterways and out-competed native plants, threatening water supplies, especially along the eastern side of the continent.

The larvae of the weevil damage the plant by tunnelling through its stems, breaking them down and causing fungal infections which hinder their ability to reproduce.
