You need a rail and dead insect to get the sort of super detailed photos in the article. But you can get decent photos of live insects handheld with a macro lens and flash (and some patience!).
I typically do this when I find a little arthropod inside; instead of killing it, I give it a free trip outside without (intentional) harm, for the small price of experiencing an alien abduction.
I literally know nothing about photography and can do really high quality macro shots. Technology is amazing.

And here's a Singapore Biodiversity Report that included photos from me (Figs 10-12) [PDF]
