In October 2007, we received a report from researchers at the UF/IFAS Center for Aquatic and Invasive Plants of an insect attacking hygrophila. Samples of the insect were collected and it was identified as the waterlily leafcutter Elophila obliteralis (Walker). Of the more than twenty Acentropinae species occurring in Florida, Elophila obliteralis (Walker) is the most common. Although its common name implies that it is a pest of waterlilies, it actually has a wide host range. Most of the damage caused by the larvae usually is superficial and rarely endangers the plant, but the damage observed on the hygrophila plants was severe (Figures 1 and 2).
