@ShaulaEvans rove beetles (Staphylinidae) are not only (one of) the largest family in the animal kingdom, but they use their abdomen to fold their wings under the shortened elytra.
In fact, their wings have distinct folding lines, but it doesn't matter if the left or the the right wing is on top of the other while folding.

I am so glad I already knew this, because @mossesandbees taught me at the #39c3 🙂
