Urania ripheus - freak

This fine example of an aberrant Urania ripheus, was submitted by an American collector.
The colour change may in fact have been caused by "Melanism" which is due to a sudden and unusual temperature drop in the moth's native environment during the pupal stage. We have shown a normal male specimen below.
