Abstract: While reducing reliance on experts, automatic species identification can provide strong technical assistance to ecological environment monitoring, biodiversity protection, pest control. However, all the datasets used for butterfly species auto-identification are currently based on specimen images, and there is a lack of ecological butterfly images. Therefore, we set up a dataset of butterfly images which includes ecological images of the butterfly species in China and corresponding annotation files in PASCAL VOC 2007 format. The dataset contains 721 butterfly images, covering 94 butterfly species. Each annotation file corresponds to an image, which contains the image size, taxonomic information and location of the butterfly species. This dataset can support researches on automatic butterfly species recognition, object detection, and insect taxonomy.
