 ## Dataset Description
 Dorsal full body images of subspecies of Heliconius Erato and Heliconius Melpomene (18 subspecies total).
-960 images with 320 specimens, each photographed in RGB with bird and butterfly acuity included (3 images of each specimen).

 The original data (Cuthill et al 2019) had misclassified species/subspecies and some locality/ collection sites were outside the known range of the butterflies. 
 It also contained hybrid and aberrant samples, that had the potential to muddle classification results. 
 To prevent this, the data was further refined by several Heliconius experts to remove hybrid and aberrant samples.
