Synonyms: Cosmophila flava,<br />

Cosmophila indica.<br />

Cosmophila is<br />

now regarded as a subgenus <strong>of</strong> Anomis.<br />

A. flava does not occur in<br />

the Americas, where its equivalent is Anomis ( Cosmophila)<br />

erosa<br />

(Pearson 1958). Records <strong>of</strong> A. erosa in the <strong>Asian</strong> continent should<br />

be referred to A. flava.<br />

Most A. flava eggs are laid on the undersurface <strong>of</strong> leaves, the young larvae<br />

are green, those <strong>of</strong> the last instar measure up to 35 mm in length and bear<br />

short, lighter-green longitudinal lines and spots. Young larvae skeletonise<br />
