Sexual Dimorphism and Allometric Effects Associated With the Wing Shape of Seven Moth Species of Sphingidae (Lepidoptera: Bombycoidea).

摘要: Sexual dimorphism is a pronounced pattern of intraspecific variation in Lepidoptera. However, moths the family Sphingidae (Lepidoptera: Bombycoidea) are considered exceptions to this rule. We used geometric morphometric techniques detect shape and size sexual fore hindwings seven hawkmoth species. The variables produced were then subjected discriminant analysis. allometric effects measured with simple regression between canonical centroid size. also normalized residuals assess nonallometric component t-test. deformations wing sexes per species assessed nonreduced residuals. found both wings all analyzed species, that responsible for much sexes. when we removed effects, observed dimorphism. It very common females be larger than males Lepidoptera, so it expected structures such as suffers order preserve their function. sources other allometry could reflection different reproductive flight behavior (long flights search mates males, host plants females).
