A change of diet

Cyperus alternifolius - a relative of the papyrus
A tiny egg is visible at 2 O'clock
The leaves are eaten and curled. Inside a curl was a pupa.
The adult emerges one morning at the end of December
The wings are inflated and the skipper seeks a vertical surface
The vertical surface is what it likes

The Giant Red-eye (Gangara thyrsis) is a well known skipper that breeds on a range of palms. Strangely, it seems like one female decided to lay its eggs (December 2009) on Cyperus a member of the Cyperaceae, rather distant from the palms. I have kept a regular lookout for a repeat of this phenomenon and it has not happened and it seems like a case of accidental oviposition. The mistake however does not seem to have had an ill effect on the young.
