-- **`image`**  
-  RGB JPEG images of individual insect specimens.
-
-- **Metadata fields**
-  - **Indexing fields**  
-    - `processid`: A unique number assigned by BOLD (International Barcode of Life Consortium).  
-    - `sampleid`: A unique identifier given by the collector.  
-  - **Taxonomic labels**  
-    - `phylum`, `class`, `order`, `family`, `subfamily`, `genus`, `species`: Hierarchical taxonomic classification  
-  - **Genetic information**  
-    - `dna_bin`: Barcode Index Number  
-    - `dna_barcode`: DNA barcode sequence   
-  - **Geographic data**  
-    - `country`, `province_state`: Collection location  
-    - `coord-lat`, `coord-lon`: Latitude and longitude coordinates  
-  - **Specimen size data**  
-    - `image_measurement_value`: Measured image property (e.g., pixel area)  
-    - `area_fraction`: Fraction of the image occupied by the specimen  
-    - `scale_factor`: Relative size normalization factor  
-  - **Split and localization**  
-    - `split`: Data partition label (e.g., train, test, val)
