Description

Comprehensive measurement of forewing length, wing melanism, and setal length from pinned butterfly specimens using digital micrometry, photography, and microscopy. Wing melanism quantified using standardized grey-level analysis of photographs.

Typical Equipment

  • digital micrometer
  • Canon Rebel XSi
  • 100-mm macro lens
  • copy-stand
  • Wild M5 microscope
  • ocular micrometer
  • MatLab program

Output Measurements

  • forewing length
  • wing melanism grey-level
  • setal length
