Welcome welcome   
I'm surprised you manage to get a macro shot using just the 18-55mm 
Did you know, you can take out your lens, and hold it in a reverse orientation, in order to get instant magnfication? 

Shutter speed, dont need to worry about it since you are using flash. from 1/80 if you dont want so much background disturbance , just set it to 1/180 and then play with both ISO and Aperture.

and also, your flikr account.... try partition it. in case lots of stalker haha 

U mean u carry fly corpse with you around?

oh..interesting.. how do you "pass" the live fly to the spider?

Mangrove Cross Spider- Argiope mangal ♀ by Ji Tan, on Flickr

Meet Joseph! Named after the scientist who caught and describe this particular spider from Singapore!

Mangrove Cross Spiders, although naturally confined to mangrove areas, they certainly have no problems living in non-mangrove areas. If this is the case, then why confine themselves in mangroves? Competition? Predatory?
Yellow-Silver Cross Spider (Argiope catenulata ♀) with blowfly prey by Ji Tan, on Flickr

One of the most beautiful Cross Spiders in Malaysia, the female Arigope catenulata displays striking silver patterns on both her abdomen and cephalothorax. Despite its relative uncommonness here, this species seem to be more abundant in Northern South-east Asia all the way to India.

Kagamine Len by RICO Lee, on Flickr

First time posting here.   
Been into this thread for quite some time as a phantom forum kaki, no dare post because all photos so nice   

Ya, purposely underexposed it to emphasis on the lume dial.
Hmmmm, like that I'll try to expose it based on your advise see see what's the outcome 
Now hands gatal, crying for macro lens   

Green Hawk Moth Caterpillar by Ji Tan, on Flickr

A beautiful Hawk Moth Caterpillar displaying its countershading colours, making it hard to see.

The horn is actually located at the rear of the caterpillar, rather than the head, and there are two fake "eyes" at the anterior part of the body, probably to scare predators.

Electric Blue Banded Phintella- Phintella vittata ♂ by Ji Tan, on Flickr

This particular species of spiders has always been on my wanted list, not because they are rare; but rather because they are so damn fast and jumpy that a proper up-closed face shot is virtually impossible.
The Phintella vittata is rather tiny plus very sensitive and will flee whenever you get close or use your flash. What's more, the black-coloured face and eyes make camera focusing difficult and inaccurate.

Managed to get a so-so shot after many tries~

Note the extra long spider fangs! Scary!

A Common Scarlet (Crocothemis servilia ♂ imm) by Ji Tan, on Flickr

Common Scarlets are very common dragonflies that can be found  in grassy areas with still water. Adult males are red in colour whereas the females are yellow in colour.

Like many other dragonflies, male Common Scarlets are very territorial and will perch and guard their favourite spots. Doing this will allow the dragonfly to secure a mating partner and a good place to lay offsprings.
Green Whip Spider (Ariamnes sp. ♀) by Ji Tan, on Flickr

This is probably one of the most amazing spiders of the world! Whip spiders are usually green to turquoise in colour, and have a very long abdomen which tapers off at the end. The spider can easily press its legs together so that its entire body looks like a thin thread which is very difficult for its predator to see.
Brown Twig Spider (Miagrammopes sp. ♀) by Ji Tan, on Flickr

Twig Spiders are brown in colour and often position their legs together to imitate a twig.

These spiders have short, thick brushes of bristles on the terminals of legs 1 and 4, and they also appear to only have 4 eyes (rather than the usual 8!).

Unlike other Uloborid spiders, the Brown Twig Spider do not build webs but rely on a single silk line to camouflage on, and believe it or not, to catch prey!

Lynx Spider (Oxyopes lineatipes ♀) with Tiger Moth Prey by Ji Tan, on Flickr

Lynx Spiders are efficient predators that rely on speed and accuracy to hunt for prey, and they are very abundant pretty much everywhere, particularly on shrubs and low vegetations.

Lynx spiders can be easily recognized by their unique, hexagonal-positioned eyes as well as their spiny legs.
