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

<p>Images of male Speckled Wood butterfly (<em>Pararge aegeria</em>) 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.</p> <p>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.&nbsp;</p> <p>&nbsp;</p> <p>Files included:</p> <ol> <li>Parage_aegeria_RAW.zip <ul> <li>Nikon raw camera images (.NEF) with ColorGauge Micro Target (Image Science Associates) colour calibration grid</li> </ul> </li> <li>Raw_example.NEF <ul> <li>Example raw image for preview</li> </ul> </li> <li>Pararge_aegeria_landmarks_jpeg.zip <ul> <li>Selected wings for landmarking and associated landmark coordinate files (.TPS)</li> <li>These images have been calibrated&nbsp;and cropped to either the left forewing or hindwing (dorsal surfaces only)</li> </ul> </li> <li>Pararge_aegeria_colour_png.zip <ul> <li>Selected wings for colour analysis (.png)</li> <li>These images have been calibrated&nbsp;and cropped to either the left forewing or hindwing (both ventral and dorsal)</li> </ul> </li> <li>Calib_cropped_FW_D_example.png <ul> <li>Example cropped and calibrated forewing image, dorsal surface (in .png format)</li> </ul> </li> </ol> <p>&nbsp;</p> <p>Nomenculture (for 2017/18 samples, principle collector EDTC):</p> <ul> <li>PA_*_XX: site number (*) and site code (XX)</li> <li>_##: within site sample number (##)</li> <li>_V or _D: ventral or dorsal surface</li> </ul> <p>Nomenculture (for 2016/7 samples, principle collector CM):</p> <ul> <li>PA_**M#: site reference(**)_Male (M)_within site number(#)</li> <li>_V or _D: ventral or dorsal surface</li> </ul> <p>&nbsp;</p> <p>This work was funded by the Natural Environment Research Council (NERC ACCE: studentship to EDTC, grant number NE/L002450/1, NE/N015711/1 awarded to IJS and NE/N015797/1 JKH).</p> <p>&nbsp;</p> <p><strong>Please contact Ilik J.
