Preliminary survey-based field investigations were conducted in March, 2026 to record the diversity, abundance, and distribution patterns of butterflies at the Kambalakonda Eco Park in Visakhapatnam, Andhra Pradesh, India. A total number of 69 butterfly species were recorded from 48 genera, which belong to five families such as Nymphalidae, Papilionidae, Pieridae, Lycaenidae, and Hesperiidae. Family Pieridae was the most dominant, accounting for 38.31% of total butterflies, whereas Nymphalidae exhibited the highest species and genus composition (36.23% and 37.50% respectively). The Lemon Emigrant (Catopsilia pomona) was the most abundant species with highest relative abundance value of 4.83, followed by Common Wanderer (Pareronia valeria), Common Gull (Cepora nerissa), Common Crow (Euploea core), and Lemon Pansy (Junonia lemonias). The genus Junonia was represented by six species, followed by Papilio with five species each. The Shannon-Wiener, Simpson, Pielou’s evenness, and Margalef’s richness indices were 3.99, 0.98, 0.94, and 8.50, respectively, indicating that the area possesses high butterfly diversity with evenly distributed populations. This investigation offers insights into butterfly diversity in the study area, underscoring the need for habitat restoration to ensure ecological resilience and support future conservation efforts.
