Comprehensive DescriptionRead full entry
H. clysonymus occurs from sea level to 2,500 m in cloud forest. Usually individuals fly rapidly and in the lowerstory. The males sit on female pupae a day before emergence, and mating occurs the next morning, before the female has completely eclosed. Adults roost at night in small groups 2-10 m above ground in twigs or tendrils (Brown, 1981).
Host plant: H. clysonymus larvae feed primarily on plants from the genus Passiflora, subgenera Tryphostemmatoides and Plectostemma (Brown, 1981). In Costa Rica H. c. montanus feeds on Passiflora apetala and P. biflora (DeVries, 1997).
