''Hylobius transversovittatus'' is a species of weevil in the family Curculionidae. It is native to the Old World where both adults and larvae feed on purple loosestrife (''Lythrum salicaria'').〔Bullock, J. A., 1992 ''Host Plants of British Beetles: A List of Recorded Associations''〕 This plant is regarded as an invasive species in North America and the weevil has been introduced into both the United States and Canada in an effort to control the plant. ==Description== The adult ''Hylobius transversovittatus'' is a dark brown colour with two irregular transverse lines of tufts of white hair. It is about thirteen millimetres long and six millimetres wide and has a narrow head and thorax and a curved trunk-like proboscis. The antennae are elbowed and the legs reddish.〔(【引用サイトリンク】publisher=Cornell University )〕 The eggs are white or pale yellow and oval in shape and hatch within about two weeks. The larvae are a creamy colour with dark brown heads and adopt a crescent shape.〔(【引用サイトリンク】title=Biological Control Agent: ''Hylobius transversovittatus'' Goeze )〕
