Prey spectra of bornean nepenthes species (Nepenthaceae) in relation to their habitat

Examination ofpitcher prey contents of 18 Bomean pitcher plants showed that pitchers attract 17 fauna groups. The upper and lower pitchers trap both flying and creeping fauna but generally the lower pitchers trap more creeping fauna and upper pitchers more flying prey species. Prey composition is...
