American soldier fly - American soldier fly

Japanese: アメリカミズアブ - あめりかみずあぶ

An insect of the Diptera family, Scorpionidae. It was introduced to Japan around 1950 after World War II with luggage from the US military, and began to increase in number, hence the name. It is 15-18 mm long. It has a long and slender body with white or brown markings on its abdomen. Its antennae are not long but ribbon-like, and the third segment is flat and large. The larvae are similar to those of the black soldier fly, with a flat dorsoventrally, many spines on the body, and a blunt tail tip. In Japan, it is distributed from various parts of Honshu south of the Kanto region to the Nansei Islands and the Ogasawara Islands. It is widely distributed in the tropical regions of Southeast Asia and Oceania, so it is presumed that it was also brought to Japan from these areas.

Japanese:

双翅目ミズアブ科の昆虫。第2次世界大戦後，1950年ごろから米軍の荷物とともに日本に移入され，増えはじめたのでこのように呼ばれる。体長15～18mm。細長く，腹部に白色または褐色の斑紋がある。触角は長くなく，リボン状で，第3節は扁平で大きい。幼虫はコウカアブの幼虫に類似し，背腹は扁平で体に多くのとげをもち，尾端は角ばらない。日本では関東以南の本州各地から南西諸島，小笠原諸島に分布する。東南アジア，オセアニアの熱帯地域に広く分布することから，日本にはこれらの地域からももち込まれたと推定される。
