Pros Sem Nas Masy Biodiv Indon 1: 1341-1347. The northern part of Manokwari is a tropical lowland forest which covered highly biodiversity. One of the biological potency is the butterfly. This study was conducted to cover biodiversity of butterfly (Papilionoidea) on the two habitat types such as secondary forest and settlement/garden area. This research was conducted about one month (May 2013) by using survey method and field observation. The result showed that about 45 species of butterfly was occupied in the northern part of Manokwari. From a total of 45 species, 32 species were found in secondary forest and 36 species were found in settlement/garden area. Shannon-Wiener index (HI) was used to analysis of diversity. The index value of Shannon-Wiener of the secondary forest was H’= 2.99 and settlement area/gardening was H’= 3.15. While the comparison of butterfly diversity from two habitats refers to t-test was t = 0,031. Evenness index of the butterfly from the secondary forest was E=0.85 and settlement/garden was E= 0.87. The Jaccard similarity index (CJ) of the butterfly from two habitats was CJ = 1.875. The population distribution of butterfly in secondary forest and settlement/garden habitats was calculated by variance (S2). Papilionidea distribution from the secondary forest was S2 = 20, Lycaenidae was S2 = 27, and Nymphalidae was S2 = 46, which means that grouping distribution, Pieridae was S2 = 5, which means that evenness distribution. While the distribution of butterfly in settlement habitat from Papilionidae was S2 = 28, Lycaenidae was S2 = 35, Nymphalidae was S2 = 62, which means that grouping distribution, Pieridae was S2 =- 18, belongs to evenness distribution.
