Butterfly A group of insects in the order Lepidoptera

Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers and the most recent analyses suggest it also contains the moth-butterflies. Butterfly fossils date to the Paleocene, which was about 56 million years ago.

Grosbeak Wikimedia disambiguation page

Grosbeak is a form taxon containing various species of seed-eating passerine birds with large beaks. Although they all belong to the superfamily Passeroidea, these birds are not part of a natural group but rather a polyphyletic assemblage of distantly related songbirds. Some are cardueline finches in the family Fringillidae, while others are cardinals in the family Cardinalidae; one is a member of the weaver family Ploceidae. The word "grosbeak", first applied in the late 1670s, is a partial translation of the French grosbec, where gros means "large" and bec means "beak".

Japanese settlement in what now constitutes modern-day Federated States of Micronesia (FSM) dates back to the end of the 19th century, when Japanese traders and explorers settled on the central and eastern Carolines, although earlier contacts can not be completely excluded. After the islands were occupied by Japan in 1914, a large-scale Japanese immigration to them took place in the 1920s and 1930s. The Japanese government encouraged immigration to the islands belonging to the South Pacific Mandate to offset demographic and economic problems facing Japan at that time.
