Races of Heliconius erato (Nymphalidae: Heliconiinae) found on different sides of the Andes show wing size differences

Abstract

Differences in wing size in geographical races of Heliconius erato distributed on the western and eastern side of the Andes are reported here. Individuals from the eastern side of the Andes are statistically larger in size than the ones on the western side of the Andes. Statistical difference is also found between individuals of different races on the western side of the Andes.
