As it says in the description of that photo, they're nothing more than an optical illusion caused by bugs flying close to a camera and being illuminated by the flash.

Object Details: In cryptozoology and outdoor photography, rods (sometimes known as “skyfish” or “solar entities”) are elongated artifacts produced by cameras that inadvertently capture several of a flying insect’s wingbeats. Videos of rod-shaped objects moving quickly through the air were claimed by some to be extraterrestrial life forms or small UFOs, but subsequent experiments showed that these rods appear in film because of an optical illusion/collusion in interlaced video recording.

They only appear in video footage or digital photos taken at night or in dark places because of the way video and digital images are captured. Unlike film, which captures a full image simultaneously, video and digital cameras scan the image from left to right and top to bottom.
This means that the upper left corner of the image was taken slightly earlier than the lower right corner. For most photos, the time difference is not noticeable because the scan happens so quickly and the objects in the image are moving so slowly (or not at all). Images taken in the dark require a longer exposure time (which is why it's hard to take a good photo at night without a tripod). When a small bug flies very close to the camera (especially if there's a flash) during the long exposure, it will be scanned in multiple locations during the same exposure, which creates the odd "rod" appearance.
