Orthopteroids are insects which historically would have been included in the order Orthoptera and now may be placed in the Polyneoptera. When Carl Linnaeus started applying binomial names to animals in the 10th edition of his Systema Naturae in 1758, there were few animals included in the scheme, and consequently few groups. As more and more new species were discovered and differences recognised, the original groups proposed by Linnaeus were split up.
