What are the differences between beetles and crickets?

Beetles and crickets are both insects, but they belong to different orders. Beetles belong to the order Coleoptera, while crickets belong to the order Orthoptera. One key difference is in their wing structure - beetles have hardened forewings called elytra that cover their hindwings, while crickets have two pairs of wings that are membranous and used for flight. Additionally, beetles have chewing mouthparts, while crickets have mouthparts adapted for chewing and biting.
