Floating pennywort weevil: feasting to control one of the UK’s most invasive aquatic plants 

Floating pennywort weevil
The floating pennywort weevil (Listronotus elongatus) is the latest biological control method to combat the highly invasive aquatic plant, floating pennywort (Hydrocotyle ranunculoides). CABI’s most recent biological control project, the first small-scale releases of the weevil occurred in late 2021, with a national release and monitoring programme launched in 2022.
