Interesting Mike. I had read this explanation before. Also it was pointed out as you increase an insect in size, just as you increase a balloon in size, it's internal volume to surface area increases disproportionately, so unless you increased the density of the air, or as the article says the oxygen in it the insect cannot supply this increased internal volume with the air required.
I also read of a similar parallel in making scale model aeroplanes. When you scale down most aircraft designs to make models of them they fly OK, but in a few cases strictly scaling down a full sized design to model size it either will not fly properly, or flies poorly. The explanation is that though you faithfully scale down the plane you have not scaled down the density of the atmosphere to match! This remains the same density as the full sized plane was computed for.
