Abstract
Hypolimnas bolina L. (Lepidoptera: Nymphalidae) is commonly known as the great Eggfly; and is a relatively common butterfly that can be found in deciduous forests and lightly wooded sides, but native to Africa, South and Southeast Asia, and Australia. Biologically, this insect undergoes a complete metamorphosis. Eggs hatch into caterpillars with spiny body surface. that develop into pupae with rough body surface. Adult emerge after seven to eight days as pupae and is usually black-bodied butterfly with a wingspan of about 70–85 millimeters. It also has a high degree of sexual dimorphism. Females are owing to the presence of both genetic polymorphism and phenotypic plasticity, whereas, males are usually monomorphic. Their dorsal wing surface is jet black but features three prominent spots, two on the forewing and one on the hind wing.H. bolina host plants include sweet potato (Ipomoea batatas) and arrow leaf sida (Sida rhombifolia). A research project was designed to monitor biological diversity focusing on adopting a specific parameter measurement for the performance of the ecosystem, such as measuring the coefficient of abundance, composition and richness of living species, in addition to measuring the main climate variables such as the size and length of the rainy season. These data are good indicators not only to reveal current conditions and trends for biodiversity, but also to give early warning signs of ecosystem performance. Three states were selected as study sites. These include Khartoum, Gezira and North Kordofan States. The eggfly specimens were collected using a butterfly sweeping net. The specimens were then preserved and sent to Agricultural Research Corporation ARC (2020) and recorded as first collection. This identification knowledge may add to the understanding of its ecological significance and role and initiation of possible control efforts if needed - since this insect proved to be plant feeder.
