Butterflies play an important role in agroforestry landscapes mainly for performing essential ecosystem services viz, pollination and maintaining prey–predatory relationships. Despite these benefits, the diversity and functional role of butterfly in agroforestry system has been poorly reported. Therefore, in this study, butterfly diversity was assessed in a circular multifunctional agroforestry system at foot hills of Nilgiris, India. This model is spread over 0.75 acre land with 24 different tree species and 8 intercrops arranged in four distinct quadrats of equal size (Q₁ = Flower, Q₂ = Vegetables, Q₃ = Curry leaf and Q₄ = Fodder). The butterflies were observed and counted by pollard walk method on alternate days in three time slots between 0900 to 1400 h during October – December, 2019. A total of eighteen butterfly species were recorded with maximum number under Nymphalidae (10) followed by Pieridae (5) and Papilionidae (3) families. Among the recorded species, Hypolimnas misippus, Pachliopta hector and Cepora nerissa comes under Schedule I and II of Indian Wildlife Act, 1972. Three species (Papilio crino, Danaus chrysippus and Hebomoia glaucippe) falls under “Rare”, seven species under “Very Common”, five species under “Common” and the remaining three species under “Not evaluated” categories of IUCN red list. The relative abundance, species richness and diversity of butterfly were found significantly different among the quadrats in different time slots of the observation. Species richness was highest in Q1 (17) followed by Q2 (15), Q3 (11) and Q4 (11) while Shannon diversity index was highest in Q1 (H = 2.81), followed by Q3 (H = 2.37), Q4 (H = 2.37) and Q2 (H = 2.22). The species richness was found highest during morning hours (0900–1000 h) followed by decreasing trend in noon. Overall Q1 was better habitat for butterflies among the four quadrats, which is due to heterogeneity of species composition and abundance of flowering species.

蝴蝶在农林业景观中发挥着重要作用，主要是为了执行基本的生态系统服务，即授粉和维持猎物-捕食关系。尽管有这些好处，但蝴蝶在农林复合系统中的多样性和功能作用鲜有报道。因此，在这项研究中，在印度尼尔吉里斯山脚下的圆形多功能农林业系统中评估了蝴蝶多样性。该模型分布在 0.75 英亩的土地上，有 24 种不同的树种和 8 种间作，分布在四个相同大小的不同样方中（Q ₁  = 花，Q ₂  = 蔬菜，Q ₃  = 咖喱叶和 Q ₄ = 饲料）。在 2019 年 10 月至 12 月期间，在 0900 至 1400 小时之间的三个时间段内，每隔一天通过波拉德步行法观察和计数蝴蝶。总共记录了 18 种蝴蝶，其中蛱蝶科 (10) 其次是粉蝶科 (5) ) 和凤蝶科 (3) 科。在已记录的物种中，Hypolimnas misippus、Pachliopta hector和Cepora nerissa属于 1972 年印度野生动物法的附表 I 和附表 II。三种（Papilio crino、Danaus chrysippus 和 Hebomoia glaucippe）属于“稀有”、“非常常见”7种、“普通”5种、IUCN红色名录“未评价”3种。蝴蝶的相对丰度、物种丰富度和多样性在不同观测时间段的象限之间存在显着差异。物种丰富度在 Q1 (17) 最高，其次是 Q2 (15)、Q​​3 (11) 和 Q4 (11)，而香农多样性指数在 Q1 (H = 2.81) 最高，其次是 Q3 (H = 2.37)、Q4 ( H = 2.37) 和 Q2 (H = 2.22)。发现物种丰富度在早晨（0900-1000 小时）最高，其次是中午下降趋势。由于物种组成的异质性和开花物种的丰富性，总体而言 Q1 是四个样方中蝴蝶更好的栖息地。
