bedbug（n.）
同时， bed-bug，又称为“寄居虫”，是一种吸血昆虫，会寄居在床和寝具上，其词源可以追溯到1772年，源自于 bed（名词）和 bug（名词）.
[The bed bug] is supposed to have been first introduced to this country in the fir timber that was brought over to rebuild London after it had suffered by the great fire; for it is generally said that Bugs were not known in England before that time, and many of them were found almost immediately afterwards in the new-built houses. [the Rev. W. Bingley, "Animal Biography; or Anecdotes of the Lives, Manners, and Economy of the Animal Creation," London, 1803]
“据信，这种臭虫最先是随着用于重建伦敦的杉木进口到这个国家的，因为普遍认为在那之前在英国并没有臭虫，而在新建的房屋中几乎立即发现了很多臭虫。”——W·宾利牧师，《动物传记; 或动物创造的生活方式和经济》，伦敦，1803年。
