Obviously a question from the uninitiated . . . . how do you know it is .42mm and not .48 or .50mm?
And how do you find the bloody things in the first place. . . .

As long as you know the magnification pretty accurately (the MPE-65 magnification scale on the barrel is accurate) you work out bug lengths on photographs (assuming they are straight on) by ratioing the bug size to the frame size - I actually use a ruler on the PC screen to do this.
eg 17cm frame width, bug length 2.3 cm mag at 5:1 fullframe.
The bug actual length= (2.3/17) * (36/5) mm = 0.97 mm.
You just get good at spotting small bugs- especially if they are on plane surfaces. I often can't tell what they are until I actually see them in viewfinder and fairly frequently zoom in on small insect poos
