Notes on the Syntomid Moth Lymire edwardsi (Grote) and Its Control as a Pest of Ficus in South Florida

Abstract

Larvae of the syntomid moth, Lymire edwardsi (Grote), occasionally are injurious to species of Ficus in south Florida. These are important ornamental and shade trees in this section. In exceptional cases some trees may be defoliated by the feeding of these caterpillars. During the summer of 1958 extensive damage by this insect was observed in Palm Beach County. Serious to complete defoliation was noted in West Palm Beach, Palm Beach, Lake Worth and at various points along the highways in Palm Beach County and adjacent counties. The 1958 infestation has been the most general and injurious that the writer has observed in ten years in the area. While Ficus on the coastal areas seemed to sustain the most injury, defoliation was observed also in the Everglades section. In addition to damage to the trees, the species may be considered a household nuisance since the pre-pupae seem to prefer the walls of buildings for pupation, if available, to any other site. As many as 35 pupae, pre-pupae and abandoned cocoons and pupal cases have been counted per square foot on the sides of buildings. In such situations they detract from the appearance of the property.
