M$^{3}$=Maths on Morphometry of Moths

[摘要] Biology and maths are usually seen as “poles apart” interestsbut amalgamated smartly, they create noteworthy findings.The present study deals with the measurement and analysis ofsix external body parameters of 430 specimens of moths (Lepidoptera:Heterocera) of twenty-one species collected fromselected areas of Delhi during 2015–2017 using light traps andopportunistic search. The measured body parts were maximumforewing length, maximum forewing width, maximumthorax width, and body length, and the derived units werebody volume and wing surface area. A mathematical tool,coefficient of variance (CV), was applied to deduce the mostconstant variable among them. As a result, forewing lengthwas found to be the most reliable parameter for taxonomicstudies.
