The life history of Heraclides garleppi lecerfi (Papilionidae: Papilioninae) is described from the Brownsberg Nature Reserve, Suriname. The hostplant is Ticorea foetida Aubl. (Rutaceae), endemic to the Guiana Shield. The 5th instar larva is distinguished by its white-based, orange subdorsal and lateral tubercles. H. g. lecerfi is not a chance hybrid, but a proper taxon. Possible reasons for its rarity are a patchy occurrence of the host plant, of which the preferred habitat is the understory of terra firme forest on lateritic rock, microhabitat, egg predation by mites and an unidentified, presumably tachinid, larval parasitoid.
