Abstract
Seventy-five species of Orthopteroid insects (terrestrial Polyneoptera, including Grillobrattera, Dermaptera, Phasmatodea, Mantodea, Blattodea, Isoptera and Orthoptera) so far collected and one species of Orthoptera whose
chirping sound was recorded in the Tama Forest Science Garden, the Forestry and Forest Products Research Institute,
Hachioji City, Tokyo Metropolis, were reported. They were predominantly those preferring forest habitats, whereas
those preferring grassland habitats were fewer. Four “Data Deficient” species, one “Vulnerable” species, one “Critically
Endangered” species and one “Unrecorded” species of the South Tama Region in the Red List of Tokyo Metropolis
and three alien species were recorded, and their present status was discussed.
