Curious: A Photo That Appears to Show Tiny People Falling From the Sky

Can you tell what this photograph is of? Snowflakes? Skydivers? Some kind of illustration involving stick figures? Here’s the description by the photographer behind the photo, Reddit user Toastbiscuit:

Was standing on a river bank surrounded my mosquitoes. Pointed my camera straight up and got this photo.

You can find a higher-resolution version of the image over on Imgur… in case you’d like to set your desktop wallpaper to a photograph of mosquitoes that look like tiny people, or something.
