Gut geschlussfolgert, aber der Effekt ist realiter minimal.

...." We found that an elytron produces positive lift at 0° geometric angle of attack, negative lift during the upstroke, and always produces drag during both the upstroke and downstroke. We also found that the lift coefficient of an elytron does not drop even at a very high geometric angle of attack. For a beetle with a body weight of 5 g, based on the quasi-static method, the fore-wings (elytra) can produce lift of less than 1% of its body weight...."
