Abstract

Biology and maths are usually seen as “poles apart” interests but amalgamated smartly, they create noteworthy findings. The present study deals with the measurement and analysis of six external body parameters of 430 specimens of moths (Lepidoptera: Heterocera) of twenty-one species collected from selected areas of Delhi during 2015–2017 using light traps and opportunistic search. The measured body parts were maximum forewing length, maximum forewing width, maximum thorax width, and body length, and the derived units were body volume and wing surface area. A mathematical tool, coefficient of variance (CV), was applied to deduce the most constant variable among them. As a result, forewing length was found to be the most reliable parameter for taxonomic studies.
