Crickets are insects, and all insects are invertebrates. They have an exoskeleton, with no backbone or spinal cord. They belong to the Phylum Arthropoda, which includes organisms such as insects, Spiders, centipedes and millipedes, and crustaceans.
Vertebrates include only some members of the Phylum Chordata: specifically, mammals, birds, fish, reptiles and amphibians.
Insects do not have bones, which means no backbone. No backbone means invertebrate. If they had bones we would be up to our knees in tiny little skeletons.
