Genus Characteristics
Members of Furcula are known as 'kitten ' or prominent moths, with larvae that possess a distinctive forked, tail-like projection (the furcula) on the eighth abdominal segment. This structure is everted when the larva is disturbed, emitting a defensive secretion. However, whether F. gigans shares all typical Furcula larval traits has not been explicitly documented.
