UV fluorescence Spotted Flying Stick Insect by melvynyeo UV fluorescence Spotted Flying Stick Insect by melvynyeo
A nice find of this rarely seen stick insect and a pleasant surprise to find it glow under UV light! :) Taken at night in Singapore.

Quote from…
Phasmids can be relatively large, ranging from 1.5 centimetres (0.59 in) to over 30 centimetres (12 in) in length. Females of the genus Phobaeticus are the world's longest insects, measuring up to 56.7 centimetres (22.3 in) in total length in the case of Phobaeticus chani, including the outstretched legs.[1] Females of the species Heteropteryx dilatata are the heaviest known phasmids, possibly weighing in excess of 65 grams.

Some have cylindrical stick-like bodies, while others have flattened, leaflike shapes. The thorax is long in the winged species, since it houses the flight muscles, but is typically much shorter in the wingless forms. Where present, the first pair of wings is narrow and cornified, while the hind wings are broad, with straight longitudinal veins and multiple cross-veins. The body is often further modified to resemble vegetation, with ridges resembling leaf veins, bark-like tubercles, and other forms of camouflage. A few species, such as Carausius morosus, are even able to change their pigmentation to match their surroundings. Many species are wingless, or have reduced wings.[3] The mouthparts project out from the head. Chewing mandibles are uniform across species. The legs are typically long and slender, and some species are capable of limb autotomy.[3] They have long, slender antennae, as long or longer than the length of the body in some species.

All phasmids possess compound eyes, but ocelli are only found in some winged males.[3] Phasmids have an impressive visual system that allow them to perceive significant detail even in dim conditions, which suits their typically nocturnal lifestyle. They are born equipped with tiny compound eyes with a limited number of facets. As the insect grows through successive molts, the number of facets is increased along with the number of photoreceptor cells in the eye. The sensitivity of the adult eye is at least tenfold that of the first instar nymphs. As the eye grows more complex, the mechanisms to adapt to dark/light changes are also enhanced: eyes in dark conditions evidence less screening pigments, which would block light, than during the daytime, and changes in the width of the retinal layer to adapt to changes in available light are significantly more pronounced in adults. However, the larger size of the adult insects' eyes makes them more prone to radiation damage. This explains why fully grown individuals are mostly nocturnal. Lessened sensitivity to light in the newly emerged insects helps them to escape from the leaf litter wherein they are hatched and move upward into the illuminated foliage. Young stick insects are diurnal feeders and will move around freely, expanding their foraging range.[4]

I take it this one doesn't normally glow like that. I somehow doubt posing as a glo-stick is often useful in nature.

Really neat polka dots, looks like something that belongs in a blacklit bowling alley. Sweet shot of this spotty stick insect!

What an amazing capture!  What sort of UV light do you use, in particular what sort of wavelength do you find best to get the florescence?
melvynyeo Featured By Owner Feb 18, 2014
Thanks. I'm using 365nm UV torch. This wavelength look dim compared to 395-400nm but it will not cast blueish light on the surrounding.…

The link is the exact model i bought. All in all among me and my friends, we have 10 over uv torch from 365 to 400nm and this torch is the best. Some other 365nm torch cast too much white light on the surrounding.

Thank you, I have a 395 NM light, but it puts out too much blue light to use for photography, this one that you linked will do nicely!
