| # IndoLepAtlas — Indian Lepidoptera & Host Plants Dataset |
|
|
| A large-scale computer vision dataset of Indian butterflies, moths, and their larval host plants. Sourced from [ifoundbutterflies.org](https://www.ifoundbutterflies.org/) with public CC-licensed photographs. |
|
|
| > **Inspired by:** [iNaturalist](https://www.inaturalist.org/) | **Domain:** Indian Wildlife & Biodiversity |
|
|
| ## Dataset Overview |
|
|
| | | Butterflies | Host Plants | Total | |
| |---|---|---|---| |
| | **Species** | ~967 | ~127 | ~1,094 | |
| | **Images** | ~60,000 | ~700 | ~60,700 | |
| | **Source** | ifoundbutterflies.org | ifoundbutterflies.org | — | |
|
|
| ## Motivation |
|
|
| Existing CV datasets (ImageNet, iNaturalist) under-represent Indian biodiversity. India hosts **~1,500 butterfly species** — many endemic and poorly documented in digital datasets. This dataset enables: |
|
|
| - **Species classification** of Indian butterflies and host plants |
| - **Object detection** with auto-generated bounding boxes |
| - **Ecological analysis** of butterfly-plant host relationships |
| - **Diagnostic analysis** using pretrained models |

| ## Metadata Fields |
|
|
| ### Butterflies (`metadata.csv`) |
| `image_id, filename, species, common_name, family, subfamily, genus, order, life_stage, sex, media_code, location, state, date, credit, source_url, source, split` |
|
|
| ### Plants (`metadata.csv`) |
| `image_id, filename, species, family, genus, image_type, media_code, location, state, date, credit, butterfly_hosts, source_url, source, split` |
|
|
| ## Annotation Format |
|
|
| - **YOLO** (per image): `<class_id> <x_center> <y_center> <width> <height>` (normalized) |
| - **COCO** (`annotations.json`): standard format with `images`, `categories`, `annotations` |
| - **Classes**: Species-level (~1,094 classes). See `annotations/classes.txt` |
|
|
| ## Classes |
| - The dataset contains images for individual butterfly species: |
| - ~1,000 Butterfly Species |
| - 410 BUtterfly Families |
| - ~500 Butterfly Species with substantial (>40) images |
| - ~700 Plant species |
| - The hero images for each species, each class here, are avialable under the data tab. |
|
|
| ## Ethical Guidelines |
|
|
| - All images are from publicly available sources (ifoundbutterflies.org) |
| - Photographer credits are preserved in metadata via OCR extraction |
| - No human faces or personal information in the dataset |
| - Source URLs and attribution maintained for every image |
