You can use a black light to detect body fluids. It’s actually a good way to look for pet urine or make sure a bathroom or hotel room is really clean. Cat urine, in particular, glows very brightly under ultraviolet light. Urine glows under a black light primarily because it contains the element phosphorus.

Other substances or spills that glow beneath a black light include the antifreeze used inside a vehicle. Invisible inks made from lemon juice become easy to read beneath the luminosity of a black light.

Chlorophyll Glows Red Under Black Light Chlorophyll makes plants green, but it also fluoresces a blood red color.

If the room is too bright, your UV light may produce little to no glow. Shine your black light – Try to find the exact location of the odor, and shine your light at it. If there is in fact cat urine in that area, it will fluoresce as a pale yellow color with a possible faint light green tinge.

Wavelengths in a blacklight cause phosphorous and proteins in the urine to glow, making it easier to spot old stains. Pet stains that weren’t cleaned properly with an enzyme-based cleaner will show up under UV light as well.

Body fluids, such as semen, blood and urine, contain phosphors, which explains the use of blacklight in forensic investigations. Modern paints contain particles that can fluoresce under a blacklight, but older paints don’t, which helps antiques or art dealers recognize forgeries, says Science World.

Biological Fluids Beneath a black light, blood turns black, unless sprayed with luminol which gives it a blue-glow. Saliva, semen and urine also glow when hit with a black light.

Many arthropods (insects, spiders, and relatives) have a secret: they glow under ultraviolet light. Lightning bugs and other bioluminescent animals produce their glow from a chemical reaction. Scorpions and some relatives produce a blue-green glow via fluorescence.

It likes to sunbathe and typically holds its front two pairs of legs together pointing forwards. During mating the male presents the female with a carefully wrapped insect as a present.

They have the best eyesight and yes they see you. You’re guess is as good as mine. ‘YOU LOOKING AT ME PAL’. Many spiders dont have great eyesight, they rely on movement within their web, at which they are extremely adept, or changes in air pressure around them, thats why some are so hairy.

Wombats, other Australian animals glow in the dark under UV light, scientists discover

• The research got glowing reviews.
• Scientists have discovered that wombats, platypi and other Australian mammals glow in the dark under ultraviolet light, the Australian Broadcasting Corporation reported.

Low-light conditions are relatively rich in ultraviolet light, and UV vision is generally thought to be important to nocturnal animals. Because of this, Anich thinks the pink glow has something to do with night-time perception and communication.

Many arthropods also fluoresce thanks to the outermost layer that that produces the glow, Wired previously reported. Stick insects, millipedes and grasshoppers all light up under UV light.
