''Myrmecia esuriens'', also known as Tasmanian Inchman, is a species of bulldog ant that is native to Tasmania. ==Morphology== The largest size of this bull ant species is reached by the queen, approximately long. Males ("drones") grow to , and the worker ants average long.〔 Within its genus, ''M. esuriens'' is a medium-sized species, as sizes for ''Myrmecia'' range from to more than .〔〔 The main body of the ant is black with a single segment of the abdomen, the postpetiole, coloured an orange-red. The mandibles, antennae, and legs of the ants are also orange-red. The hair on the ant is yellow, and is short on the head, thorax, and legs and longer on the gaster. No hair is present on the scapes.〔〔 The mandibles are long and straight, and of the eleven teeth present, the third, fifth, seventh, and ninth are wider and longer than the other seven. The Tasmanian Inchman has good eyesight, useful outside of the nest for defence and foraging.〔〔 Unusually for ants, the queens are apterous (i.e., wingless), like workers, and thus these queens are called ergatoid (i.e., worker-like) to be distinct from alate queens that have wings.〔〔 This corresponds with the consideration of the ''Myrmecia'' genus as primitive, with several features, such as the presence of ocelli and a well-defined mesonotum, suggestive of earlier evolutionary development.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Myrmecia esuriens」の詳細全文を読む スポンサード リンク
