The research with the aim to know taxonomic composition, abundance, diversity, evenness of leaf- and planthoppers on rice ecosystem at Samosir Island in Sumatera-Indonesia has been done. Leaf-and planthoppers were collected by using insect net in stubble field and vegetation periods of rice crops. Hoppers sampling has been carried out for six months (May to October 2014 and 2015) at four sites sampling. Research result showed that there was eleven hoppers species on rice ecosystem of Samosir island, four species (Nilaparvata lugens, Sogatella furcifera, Nisia nervosa, Siphanta sp. ) belonged to planthopper (Fulgoroidea) and seven species (Nephotettix virescens, Nephotettix nigropictus, Cofana spectra, Recelia dorsalis, Thaia ghauri, Empoascanara sp. and Cicadellid sp. ) to leafhopper (Cicadelloidea). Dominant hoppers and very frequent their occurrence were N. nigropictus, Thaia ghauri, Cofana spectra and Recelia dorsalis. Species richness and hopper abundance in stubble field period was higher than in vegetation period. Abundance, diversity and evenness of hoppers in the year 2014 were higher than in 2015.
