Australian plague locust : ウィキペディア英語版 | Australian plague locust
The Australian plague locust (''Chortoicetes terminifera'') is a native Australian insect in the family Acrididae and a significant agricultural pest. Adult Australian plague locusts range in size from 20 to 45 mm in length and the colour varies from brown to green. In profile, the head is higher than the thorax, and the thorax has an 'X' shaped mark. The legs have a reddish shank and the wings are clear other than for a dark spot on the end. ==Range and habitat== The locusts occur naturally in far north-western New South Wales and the adjoining areas of Queensland and South Australia as well as Western Australia. From these areas, the locusts can expand from time to time to be found in the agricultural areas of South Australia, New South Wales—including the Riverina— and Victoria. The locust can be found in a variety of grassland and open wooded habitats across the inland areas of the Australian mainland. Upper level winds may occasionally carry locusts to coastal areas of the mainland and northern Tasmania and may establish populations in the eastern valleys of the Great Dividing Range; these populations usually fail to establish themselves for more than a few generations.
