Separate_segmented_train_test_splits_80_20

This subset of the 2018 NEON Ethanol-preserved Ground Beetles dataset was generated as part of a project at BeetlePalooza 2024. The code to generate this collection of images is available in the Beetle_Palooza_image_separation notebook provided in the dataset processing repository. There were two directories of images generated during this processing group_images_masks/ and separate_segmented_beetle_images/, which have associated metadata files in the metadata directory of the processing repo; they are group_images_masks_sb.csv and group_images_sb.csv, respectively.

About this Data Subset

This folder contains cropped images of approximately 7,000 individual images for beetles from the following species (not really 12 species: repeated species epithet in Pterostichus melanarius melanarius indicates this is the nominotypical subspecies of Pterostichus melanarius).

1. Calathus advena
2. Cyclotrachelus torvus
3. Chlaenius aestivus
4. Euryderus grossus
5. Harpalus pensylvanicus OR Pterostichus pensylvanicus --- this species epithet seems to have two different genera associated to it and will thus require more effort for alignment. Hopefully, it's just a matter of merging on an ID from the original dataset but look at the filename generation to figure it out.
6. Pterostichus melanarius
7. Pterostichus restrictus
8. Pterostichus melanarius melanarius — nominotypical subspecies of Pterostichus melanarius
9. Pterostichus lachrymosus
10. Carabus goryi
11. Cratacanthus dubius
12. Synuchus impunctatus

Please see the processing notebook for more information on how these images were generated, and see the metadata generation notebook for more information on the distribution of species.
