Elateroidea

The Elateroidea is a superfamily of beetles that includes the click beetle family (Elateridae) and the firefly family (Lampyridae).12

Click Beetles (Elateridae)

Click beetles are known for their ability to produce a clicking sound when captured by a predator. They have elongated bodies and can flip themselves into the air with a click to right themselves when overturned. Their larvae, called wireworms, have hard exoskeletons and can be destructive pests, feeding on seeds, roots, and stems. Some tropical click beetles, like those in the genus Pyrophorus, are bioluminescent.134

Fireflies (Lampyridae)

Fireflies are beetles that possess light-producing organs on their abdomens, allowing them to create rhythmic flashes. This bioluminescence is used for communication, primarily to attract mates. While many adult fireflies feed on pollen and nectar, their larvae typically prey on snails and slugs. Some wingless female fireflies are also known as glowworms and emit light continuously.25
