Abstract
Keanekaragaman kupu-kupu menurun seiring dengan menurunnya keragaman tumbuhan atau komposisi vegetasi pada habitatnya dikarenakan perubahan habitat alami menjadi lahan perkebunan ataupun pertanian yang dapat menyebabkan terbentuknya fragmen habitat dan menimbulkan munculnya wilayah tepi. Penelitian ini bertujuan untuk mengetahui dan membandingkan keanekaragaman kupu-kupu (Subordo:Rhopalocera) berdasarkan komposisi vegetasi dan pengaruh efek tepi di kawasan Agroekosistem Desa Jatiarjo, Prigen, Jawa Timur. Pengambilan data kupu-kupu di lapangan dilakukan dengan menggunakan metode Pollard Walk yang dimodifikasi dengan metode jelajah , kemudian dilakukan inventarisasi komposisi vegetasi dan pengukuran faktor lingkungan. Identifikasi dilakukan di lapangan berdasarkan morfologi dari kupu-kupu seperti bentuk tubuh, warna sayap, dan bentuk antena. Analisis data dilakukan secara deskriptif kuantitatif. Hasil penelitian menunjukkan komposisi dan kelimpahan kupu-kupu berbeda di setiap tipe habitat tergantung dari jenis spesies dan komposisi vegetasi. Semakin menuju ke arah hutan, keanekaragaman dan kelimpahan cenderung meningkat, dimana jumlah individu transek 1 pada wilayah tepi kebun sebanyak 41 individu semakin mengarah ke hutan jumlah meningkat menjadi 50 individu, sebaliknya transek 2 jumlah awal 37 semakin transek mengarah ke interior hutan menjadi 55 individu. Hal ini menunjukkan adanya pengaruh efek tepi terhadap kelimpahan dan distribusi spesies kupu-kupu. Habitat tepi cenderung didominasi spesies food plant (37,4%) dan tumbuhan multifungsi (food & host plant) (22,0%), sedangkan habitat interior hutan lebih didominasi dengan host plant (40,7%). Wilayah tepi cenderung dihuni oleh spesies generalis, sedangkan hutan lebih banyak dihuni spesies spesialis. Pola distribusi ini menggambarkan efek tepi dan komposisi tumbuhan daapt mempengaruhi komposisi dan keanekaragaman kupu kupu. Kombinasi kedua tipe habitat ini menciptakan mosaik ekologis penting untuk kelangsungan komunitas kupu-kupu dari fase larva hingga dewasa.

Butterfly diversity decreases in line with the decline in plant diversity or vegetation composition within their habitat. This decline is often caused by the conversion of natural habitats into agricultural or plantation areas, leading to habitat fragmentation and the emergence of edge habitats. This study aims to examine and compare butterfly diversity (Suborder: Rhopalocera) based on vegetation composition and the influence of edge effects in the agroecosystem of Jatiarjo Village, Prigen, East Java. Butterfly data were collected in the field using a modified Pollard Walk method combined with an exploratory approach. An inventory of vegetation composition and measurement of environmental factors were also conducted. Butterfly identification was performed in the field based on morphological characteristics such as body shape, wing coloration, and antenna structure. Data analysis was carried out using descriptive quantitative methods. The results showed that butterfly composition and abundance varied across habitat types depending on species and vegetation composition. Diversity and abundance tended to increase as the habitat transitioned from edge areas toward forest interiors. In Transect 1, the number of individuals increased from 41 in the garden edge to 50 in the forest area. Similarly, in Transect 2, the number increased from 37 at the edge of the rice field to 55 in the forest interior. These findings indicate the influence of edge effects on butterfly abundance and species distribution. Edge habitats were predominantly composed of food plants (37.4%) and multifunctional plants (food & host plants) (22.0%), whereas forest interiors were dominated by host plants (40.7%). Edge areas were mainly inhabited by generalist species, while forest interiors were more populated by specialist species. This distribution pattern illustrates that edge effects and vegetation composition significantly influence butterfly diversity and composition. The combination of both habitat types creates an ecological mosaic that is crucial for the survival of butterfly communities from larval to adult stages.
