The Great Eggfly (Hypolimnas bolina), is also called the Blue Moon Butterfly in New Zealand or Common Eggfly, and is a species of nymphalid butterfly.
H. bolina is a black-bodied butterfly with a wingspan of about 70–85 millimetres (2.8–3.3 in). The species has a high degree of sexual dimorphism.
The female is mimetic with multiple morphs.
