All of the fly images were taken by me, randomly, as I see a fly, and have a camera to hand.
Other images have been downloaded from unsplash. Unsplash provides royalty-free images. They ask that we credit the contributing photographers, which is the least we can do.
Below are a few of the contributing photographers that have provided images for this website. Thanks.
