A 2000 report by staff at "The Straight Dope" also explained rods as such phenomena, namely tricks of light which result from how (primarily video) images of flying insects are recorded and played back, adding that investigators have shown the rod-like bodies to be a result of motion blur, if the camera is shooting with relatively long exposure ...
An animated sequence of simulated appearances of a red flower (of a zonal geranium) and background foliage under photopic, mesopic, and scotopic conditions. The Purkinje effect or Purkinje phenomenon (Czech: [ˈpurkɪɲɛ] ⓘ; sometimes called the Purkinje shift, often pronounced / p ər ˈ k ɪ n dʒ i /) [1] is the tendency for the peak luminance sensitivity of the eye to shift toward the ...
Rod cells are photoreceptor cells in the retina of the eye that can function in lower light better than the other type of visual photoreceptor, cone cells. Rods are usually found concentrated at the outer edges of the retina and are used in peripheral vision .
All of the effects on a flapping wing may be reduced to three major sources of aerodynamic phenomena: the leading edge vortex, the steady-state aerodynamic forces on the wing, and the wing's contact with its wake from previous strokes. The size of flying insects ranges from about 20 micrograms to about 3 grams.
In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water.

Viktor Stepanovich Grebennikov (Russian: Виктор Степанович Гребенников; 23 April 1927 in Simferopol – 2001 in Novosibirsk) was a self-proclaimed Russian scientist, biologist, entomologist and paranormal researcher best known for his claim to have invented a levitation platform which operated by attaching dead insect body parts to the underside.
The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens, which refracts light rays so that a point source of light is seen as a line or streak of light. [2] Due to the optical properties, the streak of light is seen perpendicular to the axis of the cylinder. [3] Maddox rod and pen torch used in Maddox rod testing
