This is a closer crop of the dead fly that I stacked up.
2x extension tubes & bellows fully wound out with a 50mm macro lens on the end. Three cheap LED lights on stalks from Ikea and a piece cut off an Omeprazole box for the background. Three half ping pong balls to form a "light tent" around the fly, which had it's arse glued to a pin stuck into a bit of foam taped to the tripod. All popped into Helicon Focus on auto settings.
