- Abstract
Sexual dimorphism (SD) is a common phenomenon in animals, especially in invertebrates and poikilothermic vertebrates, which can cause body size differences of males and females in a species. Rice ear bugs [Leptocorisa oratorius Fabricius (Hemiptera: Alydidae)] are a significant rice pest in Indonesia, and the data about sexual dimorphism of this species is little known. This research aims to describe the sexual dimorphism of rice ear bugs. The study was conducted by sampling on the suburbs area’s paddy fields in Yogyakarta with a purposive sampling method, followed by the dissection and analysis of 22 morphometric descriptors. Results have shown a significant sexual dimorphism on the antennae length, tarsus length, and prothorax length. Male L.oratorius generally have longer antennae length, tarsus length, and prothorax length than females. There are no significant differences between male and female descriptors, but some female descriptors are bigger than males. There is a possibility that mating selection pressure was driven by the sexual dimorphism of L. oratorius.
