 In Japan's Ogasawara Islands, the introduced Carolina anoles have caused declines in native lizards and diurnal insects, including the near-extinction of the endemic "Celastrina ogasawaraensis" butterfly and five dragonfly species.This may be due to the ecological naïvete of the insects (before the introduction, there were no diurnal, highly arboreal lizards) and a very high anole density on these Japanese islands, as similar insect declines have not been reported from the Bahamas (which already had diurnal, arboreal lizards), or Guam, Saipan and Hawaii (where the anole density is lower).In addition to Florida, the Cuban green anole has been introduced to the Dominican Republic, São Paulo (Brazil) and Tenerife (Spain).
