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
