Description

Size	65 mm to 70 mm
Description	The Great Eggfly occurs in Malaysia and Singapore in two subspecies, the other subspecies being the Jacintha Eggfly (H. bolina jacintha). Of particular interest is the polymorphism in the females of both subspecies. The males of the Great Eggfly differ from the Jacintha Eggfly in that the postdiscal white dots are absent, whilst in the female, the submarginal white fasciae are much reduced, taking a "V"-shaped form and separated. The female occurs in four principal forms and two subsidiary forms which are connected by a variable spectrum of intermediates, such that it is difficult to find two exactly matching examples.
