dc.description.abstractAlthough a substantial amount of research has been done on all aspects ofHeliconius biology and their ecological interactions with Passiflora, there has not hitherto been a phylogenetic examination of this association for coevolution. To test the HeliconiuslPassilfora association for coevolutionary congruence, phylogenies for each group were established and compared. The phylogeny for 14 species ofHeliconiinae from Costa Rica was based on combined sequence data from rRNA ITS 2 and partial EF-1a gene regions. For the Passifloraceae, 17 host plant species were utilized to establish a phylogeny based on tRNALeucine and ITS 1/5.8S1 ITS 2 sequence data. The phylogenies for both groups were largely in agreement with current classification (for Passifloraceae) and previously established phylogenies. Associations with the large subgenera Passiflora and Decaloba correspond with the two major Advanced Radiation groups in Heliconius. Although strict congruence above subgenus level was not observed, broad scale congruence was evident. One main host shift as well as other possible explanations for lack of strict congruence are suggested.en_US
