Wing morphological responses to latitude and colonisation in a range expanding butterfly

Images of male Speckled Wood butterfly (Pararge aegeria) wings that were collected (during 2016-2018) across a recently expanded range in mainland Britain. The wings were used to study changes in morphology (size and shape) and colour with colonisation history, latitude and temperature.

Images were taken by Evelyn D. Taylor-Cox and Claire Williams in the Lepidoptera Ecological Genetics Group at the Univeristy of Liverpool, under the supervision of Ilik J. Saccheri. 

Files included:

1. Parage_aegeria_RAW.zip
   • Nikon raw camera images (.NEF) with ColorGauge Micro Target (Image Science Associates) colour calibration grid
2. Raw_example.NEF
   • Example raw image for preview
3. Pararge_aegeria_landmarks_jpeg.zip
   • Selected wings for landmarking and associated landmark coordinate files (.TPS)
   • These images have been calibrated and cropped to either the left forewing or hindwing (dorsal surfaces only)
4. Pararge_aegeria_colour_png.zip
   • Selected wings for colour analysis (.png)
   • These images have been calibrated and cropped to either the left forewing or hindwing (both ventral and dorsal)
5. Calib_cropped_FW_D_example.png
   • Example cropped and calibrated forewing image, dorsal surface (in .png format)

Nomenculture (for 2017/18 samples, principle collector EDTC):

• PA_*_XX: site number (*) and site code (XX)
• _##: within site sample number (##)
