Cicadellidae are insects of agricultural importance because they are plant pathogens vectors. Oncometopia clarior is responsible for transmission of Yam mild mosaic virus that causes yield losses in yam crops. This study describes the egg biology of leafhopper Oncometopia clarior. Adult females were collected in yam crops and confined in oviposition cages with Dioscorea rotundata plants, the leaf with postures were removed and the eggs were incubated. Oviposition occurs on the underside of the leaf in endophytic form. The eggs were laid in rows of 4 to 25 and these were covered with brochosome. Their size was 2.39 mm ± 0.1197 in length and 0.53 mm ± 0.062 width; they showed an elongated shape with rounded ends. The duration of embryonic period was 6.58 ± 0.98 days.
