Well that beats us all

However I doubt that one could easily get a shot like that with a straight macro lens without cropping from the original shot - which of course is not ideal as its cutting down on overall image usage.
I have use a 1.4 teleconverter on a Sigma 150mm macro lens to get a result like the following:
which looks to be similar to the magnification that the other setup is getting - possibly a little less - so maybe a 2*TC backed off just a bit.
As for the clarity that is coming from 3 places:
1) ambient lighting
2) editing - one has to have a good image first, but good editing can give that extra punch that is seen in many shots
3) flash - this is not always needed as ambient lighting can be used if one has a good enough light source and reflectors, but flash is often used and a good solid flash setup can give a very big increase to overall image quality
Oh and the water is probably from one of hte following sources:
1) early morning dew - early morning also very likley since this was a tripod shot and dragons don't always hang around - this early morning for when insects are still cold from the night and not yet warmed up and active.
2) rainfall - just after a rainstorm - colder weather so the insect is more likley to be a bit more docile as it again has to warm up.
3) spraycan - though it would certainly need to have a colder insect to start with - morning again - the water in the sprayer (clearly not pointed right at the bug) used to add more water to the scene - the bug staying still as its cold
Not some people catch bugs and fridge them to get them slow - its not something that I do and many other macro shooters also tend to refrain from it as the bugs do not alway recover from the effect - besides in the field is much more fun and early mornings won't kill you (heck you might even see some nice sunrises

)
