Many families, such as Dermestidae,

Histeridae, and Byrrhidae, have grooves in

the thorax into which the antennae or limbs

are withdrawn for protection when not in

use. Many weevils, especially the tribe

Cryptorrhynchini, have a groove in the

center of the underside of the thorax to

accept the rostrum. The thorax is often

decorated; for example, in the common

Seven Spot Ladybird Coccinella

septempunctata (Coccinellidae), the thorax

has white “eye spots” that are much larger

than the beetle’s actual eyes. In click beetles

of the Pyrophorini (Elateridae), the bright

bioluminescent “headlamps,” probably also false

eyes, are on the upper surface of the pronotum.
