The life history of Jamides celeno has been well documented across its range. The larvae feed on plants from six families and are attended by ants from seven genera. This paper documents a new host plant record and additional attendant ant species from observations made in Cat Tien National Park, Vietnam. We discuss ecological and behavioral traits of the early stages of J. celeno and their associated ants, and suggest that the categorization of J. celeno as a facultativemyrmecophile may be incorrect.
