Another Beautiful Spider Under Ultraviolet
In a recent post, I highlighted an instance where a bird dung spider looked radically different when exposed to ultraviolet light. This week, we found another spider emitting a beautiful cyan hue under ultraviolet. It seems to fluoresce only under the wavelength of 365nm, rather than the more common 395nm ultraviolet wavelengths. This is a lengthy post with over 50 photos of glorious bugs, be warned!! 🙂
Huntsman Spider (Gnathopalystes sp.)
Found 2 of these Jade Huntsman Spiders , this is the female. The male is typically brown as seen in an earlier post on sexual dichromatism.
Huntsman Spider (Gnathopalystes sp.)
Switched off the lights, opened the shutter for 20s with the Huntsman Spider under UV light. What resulted are beautifully cyan-tinted carapace and legs. At the same time, the spider caught what looked like a caddisfly which was still struggling when the shutter was open.
Huntsman Spider (Gnathopalystes sp.)
Tried positioning the UV light all over the place to get a slightly different feel. The prey was obviously still struggling. Amazingly the abdomen remains almost in it’s natural colour.

View from the front, not as impressive as the dorsal view though.
Earwigs (Dermaptera)
Greeted by mating Earwigs at the entrance

They ran about, but were still connected!
Feather-Legged Spider (Uloboridae)
James found this Twig-Like Feather-Legged Spider with it’s egg sac. Even the egg sac looked like a twig!
Caterpillar? Pupa? or dead?

Huntsman Spider (Heteropoda sp.)
Victor found this unique looking purplish Huntsman Spider
Huntsman Spider (Heteropoda sp.)
I went really low to get a peek of it’s face. Had to shift some of the leaf litter from covering the face, but still missed out one on the left!!
Huntsman Spider (Heteropoda sp.)
The spider started running around, but into the open so that I could get a clearer shot of the carapace.
Huntsman Spider (Heteropoda sp.)
And this time a much clearer shot of the eyes and chelicerae!
Huntsman Spider (Heteropoda sp.)
A rather majestic pose, don’t you think? 🙂
Katydid (Tettigoniidae)
I chanced upon this Katydid in an odd position, and realized that it was laying eggs into this branch! Tan Ming Kai suggested that this could be Carliphisis sp.
Harvestman (Opiliones)
One of the many Harvestmen that we saw in the night. This carried a bowl-shaped fungus, but what was on the “bowl”? Eggs? Sperm? Or just dirt?

Harvestman (Opiliones)
The legs of this Harvestman are often too long for me to get into frame. This was the widest I could get!
Harvestman (Opiliones)
Just 2 meters away, Melvyn was shooting another Harvestman , this time munching on a fresh prey
Harvestman (Opiliones)
What was it eating? Caddisfly?

Again, my widest view of the scene
Feather Legged Spider (Miagrammopes sp.)
Melvyn found another Feather Legged Spider with egg sac. Notice how it mimics a twig even with the egg sac!
Planthopper (Fulgoromorpha)
A tiny speck on a plant stalk turned out to be this beautiful Planthopper

View from the top, probably a nymph
Planthopper (Fulgoromorpha)
Clearest view I could get. Due to the size of this planthopper, it was extremely difficult to get everything sharp.
Planthopper (Rhynchomitra sp.)
Another lovely Planthopper
Unknown eggs
Unknown eggs that had already hatched
Praying Mantis (Mantodea)
A tiny Praying Mantis pretending to be a twig as well
Straight-Snouted Weevil (Brentidae)
Melvyn found a Straight-Snouted Weevil with lots of mites on it’s head!
Straight-Snouted Weevil (Brentidae)
After just a few shots, the Straight-Snouted Weevil decided to take off. Bye bye!!!
Beetle larva?
Melvyn the radar king found this little wormy creature. Beetle larva of some sort?
Wolf Spider (Lycosidae)
Found this Wolf Spider carrying her babies!
Wolf Spider (Lycosidae)
Wider view of the Wolf Spider . It was very well camouflaged on the rock.
Wolf Spider (Lycosidae)
Going closer rendered parts of the background out of focus, allowing us to see the spider clearly.
Longhorn Beetle (Anancylus griseatus)
An old favorite, Longhorn Beetle!
Longhorn Beetle (Anancylus griseatus)
Looking closer, we found 2 different mites on the neck of the Longhorn Beetle

Tried to picture the long horns, but this was the max I could go
Big-Jawed Spider (Mesida sp.)
James found this male Big-Jawed Spider
Big-Jawed Spider (Mesida sp.)
Looking closer, this Big-Jawed Spider had beautiful metallic plates on it’s abdomen.
Big-Jawed Spider (Mesida sp.)
The female Big-Jawed Spider was just nearby!! Lovely silvery plates!

Big-Jawed Spider (Mesida sp.)
Not easy to shoot this silvery Big-Jawed Spider – the abdomen would typically be overexposed.
Darkling Beetle (Ceropria sp.)
Melvyn found this Darkling Beetle resting on a log. Sometimes we called this the “oil-spill” beetle for the colours, but this particular one was so colourful that we called it the rainbow beetle!
Darkling Beetles (Amarygmus sp.)
More Beetles nearby, probably before or after making out.
Huntsman Spider (Sparassidae)
Found many Huntsman Spiders running about and took some record shots.
Orb Web Spider (Eriovixia sp.)
Found a lovely bright orange coloured Orb Web Spider
Orb Web Spider (Eriovixia sp.)
Classic view for documentation
Caddisfly (Trichoptera)
Lots of these around. Caddisfly?

Velvet Worm (Eoperipatus sumatranus)
The surprise find of the night came from Victor. Nobody believed him when he shouted that he found a Velvet Worm … lol
Velvet Worm (Eoperipatus sumatranus)
We let it crawl up a twig to capture pictures of the bottom of the Velvet Worm. Sho cute!!
Velvet Worm (Eoperipatus sumatranus)
The Velvet Worm looked quite fat.. chubby!
Tarantula (Theraphosidae)
Finally got to use my fish-eye lens when this Tarantula didn’t take Melvyn’s presence (in the background) lightly.
Tarantula (Theraphosidae)
I tried to say hi and be friendly… I really did.
