General Species Information

Host Plant: Rubiaceae, including Smooth buttonplant (Spermacoce glabra), starclusters (Pentas species), Borreria, Manettia; and Bignoniaceae

Historical Range: Florida, Texas, Caribbean and Central America

Our Experience with this Species: Xylophanes tersa has been a consistantly common species in the Keys. While it us usually not abundant, they are regular in appearance at mercury vaopr lights. We have found them in every month of the year and have been present in almost every location we have surveyed in the Keys.

Notes: Larvae of this species can be a pest to penta flower beds as they will quickly defoliate large bushes but this is moreso something that occurs on the mainland of Florida.
