Other studies on longevity of fruit-feeding nymphalids in highland dipterocarp forest of Sabah (Beck & Schulze 2000) showed that some butterflies may live up to six weeks, in broad agreement with our results. These results contrast with data from neotropical rainforests where pollen-feeding Heliconius butterflies (Heliconiinae) have been recorded to live up to 6 months longevity (Dunlap-Pianka et al. 1977). In temperate regions, adult longevity of some butterflies may be similarly long but only in species where adults are inactive during the winter (Pollard & Yates 1993). For temperate species where adults do not enter diapause, adult longevity is generally only 1–2 weeks (Thomas & Hanski 1997; Thomas et al. 1998).
