Butterflies are the best known invertebrate taxa with an estimated 20,000 species worldwide and occupy a prominent place in conservation programs and biodiversity assessments. However, there is a lack of knowledge on the butterfly fauna in the state of Terengganu. A butterfly survey was conducted at the Terengganu National Park from 10 March 2011 to 13 March 2011 by sweep netting method aided by baited traps.

A total of 81 butterflies were captured, consisting of 30 species from 18 genera and 5 families namely Hesperiidae, Lycaenidae, Nymphalidae, Papilionidae and Pieridae. Nymphalidae (50.62%) was found to be the most dominant family followed by Lycaenidae (30.86%), Pieridae (12.35%), Papilionidae (4.94%) and Hesperiidae (1.23%).

The Common Four-ring butterfly, Ypthima huebneri Kirby and Common Caerulean butterfly, Jamides celeno alianus (Fabricius) were the most abundant butterfly species recorded with 15 individuals (18.52%) and 13 individuals (16.05%) respectively of the total individuals sampled in the study.

A checklist of butterflies was presented as the outcome of the study.  Results for the study were influenced by the short sampling period and the heavy rain which occurred during the sampling period. Comprehensive studies are recommended to expand overall knowledge and understanding of butterfly fauna in the Terengganu National Park.
