A beetle's hard forewings protect the delicate flight wings folded underneath them.

The longer version

Forewings act as protective cases in beetles. At rest the delicate flight wings fold away beneath them, shielded from snagging, tearing, and abrasion while the animal pushes through soil, leaf litter, or tight spaces. The hardened covers also cut water loss, sealing much of the body.

Taking off means lifting those cases first so the membranous wings underneath can unfold and beat, which is why beetle flight often starts with a pause and an audible clicking buzz. Paying that cost buys durability and access to habitats that would shred exposed wings. Shape and texture of these covers vary widely, matching the way each lineage lives.
