Abstract
The study is based on 80 specimens of Danaus chrysippus (Linn.) collected during autumn and spring for morphometric variations.
Fifteen morphological characters were selected. Length of scent gland of hindwing of male autumn form was found highly variable and wingspan (WS) was found the least variable characters. Similarly in male spring form, the width of discoidal cell (DC) of forewing was found highly variable and body length was found the least variable characters. In case of female autumn form, length of costa of forewing was found highly variable while length of dorsum of hindwing was found the least
variable characters. In female spring form, dorsum length of hindwing
was found highly variable character. The least variable character was,
length of DC of hindwing. The relationships of body length with
remaining morphological characters were also studied by applying
correlation and regression analysis. Body length BL was considered as
independent variable and other characters were considered as dependent variable. There was positive correlation between body length and other characters, but the extent of increase in dependent parameters varied. As regard the comparison of different characters in butterflies collected during autumn and spring forms, the statistical analysis revealed nonsignificant difference between (BL) of male and female specimens
