The predatory Coleoptera fauna on king sago, Cycas revoluta Thunberg (Cycadaceae), in south Florida is summarized and illustrated. The king sago is a popular landscape plant, but individual plants may harbor very large populations of the long-tailed mealybug, Pseudococcus longispinus (Targioni), the cycad aulacaspis scale, Aulacaspis yasumatsui Takagi, and miscellaneous soft scales (Coccidae). The majority of beetle species observed belong to the family Coccinellidae, with 13 species representing 10 genera. Species in the genera Exochomus, Chilocorus, Curinus and Diomus are the most frequently encountered. Crowns and leaves are often inhabited by the armored scale feeder Cybocephalus binotatus Grouvelle (Nitidulidae). Generalist Carabidae are infrequently detected.
