 ## Description
+**See the [BioTrove](https://huggingface.co/BGLab/BioTrove) dataset card on HuggingFace to access the main `BioTrove` dataset (161.9M)**
 
 [BioTrove](https://baskargroup.github.io/BioTrove/) comprises well-processed metadata with full taxa information and URLs pointing to image files. The metadata can be used to filter specific categories, visualize data distribution, and manage imbalance effectively. We provide a collection of software tools that enable users to easily download, access, and manipulate the dataset. 
 
 
-## BioTrove Dataset
-`BioTrove` comprises over `161.9M` images across several taxonomic groups- including Reptilia (reptiles), Plantae (plants), Mollusca (mollusks), Mammalia (mammals), Insecta (insects), Fungi (fungi), Aves (birds), Arachnida (arachnids), Animalia (animals), Amphibia (amphibians), and Actinopterygii (ray-finned fish).  
-These taxonomic groups were chosen to represent the span of species — outside of charismatic megafauna. The images in BioTrove span `366.6K`species. 
-Overall, this dataset nearly matches the state-of-the-art curated dataset (TREEOFLIFE-10M) in terms of species diversity, while comfortably exceeding it in terms of scale by a factor of nearly 16.2 times.
+## BioTrove-Train Dataset (40M)
+`BioTrove` comprises over `40M` image samples and `33K` species across `7` taxonomic groups- seven taxonomic categories: Aves, Arachnida, Insecta, Plantae, Fungi, Mollusca, and Reptilia.  
+These taxonomic categories were chosen due to their significant impact on biodiversity and agricultural ecosystems, as well as their relative underrepresentation in standard image recognition models/foundation models.  
+Overall, this dataset nearly matches the state-of-the-art curated dataset (TREEOFLIFE-10M) in terms of species diversity, while comfortably exceeding it in terms of scale by a factor of nearly 4 times.
 
 ## New Benchmark Datasets
 We created three new benchmark datasets for fine-grained image classification. In addition, we provide a new benchmark dataset for species recognition across various developmental Life-stages.
 
 ### BioTrove-Balanced
-For balanced species distribution across the 7 categories, we curated `BioTrove-Balanced`. Each category includes up to 500 species, with 50 images per species.
+For balanced species distribution across the 7 categories, we curated `BioTrove-Balanced`. Each category includes up to 500 species, with 50 images per species, totaling of `~112K` image samples.
 
 ### BioTrove-Unseen
-To provide a robust benchmark for evaluating the generalization capability of models on unseen species, we curated `BioTrove-Unseen`. The test dataset was constructed by identifying species with fewer than 30 instances in BioTrove, ensuring that the dataset contains species that were unseen by BioTrove-CLIP. Each species contained 10 images.

 ### BioTrove-LifeStages
-To assess the model’s ability to recognize species across various developmental stages, we curated `BioTrove-LifeStages`. This dataset has 20 labels in total and focuses on insects, since these species often exhibit significant visual differences across their lifespan. BioTrove-LifeStages contains five insect species and utilized the observation export feature on the iNaturalist platform to collect data from 2/1/2024 to 5/20/2024 to ensure no overlap with the training dataset. For each species, life stage filters (egg, larva, pupa, or adult) were applied.
