Therevidae
The Therevidae are a family of flies of the superfamily Asiloidea commonly known as stiletto flies. The family contains about 1,600 described species worldwide, most diverse in arid and semiarid regions with sandy soils. The larvae are predators of insect larvae in soil. thumb|230px|left|Plate from Johann Wilhelm Meigen EuropäischenZweiflügeligen.Showing the gross features mentioned in the text (figures 5-9)

剑虻科（学名：Therevidae）是双翅目食虫虻总科下的一个科，总计包括1,600个物种，其中大部分生活在沙质土壤的干旱或半干旱区域。其幼虫在土壤中捕食昆虫的幼虫。 描述 该科苍蝇通常多毛或具有毛茸茸的外观，与食虫虻类似，两者有密切关系。但是，它们没有凹陷的脸和凸出的眼睛。它们腿很长，雌性产卵器官周围有一圈硬毛。 习性 该科苍蝇主要生活在草地和牧场，偶尔在灌木或观叶花卉上被发现。它们通常生活在沙质土壤的干旱地区。成虫只以液体为食，通常是水。它们善于飞行，不过飞行距离通常很短。它们在沙质土壤中产卵。 幼虫长且卷曲，由19段组成。它们生活在土壤中，有时在烂木头中。它们捕食甲虫幼虫和其它软体动物，它们注入毒剂，然后吸出猎物。幼虫在土壤中休眠成蛹。蛹期通常持续时间只有八到十二天。 参考资料 维基共享资源中相关的多媒体资源：剑虻科 Klaus Honomichl, Heiko Bellmann: Biologie und Ökologie der Insekten; CD-Rom, Gustav Fischer Verlag, Stuttgart, 1994 取自“https://zh.wikipedia.org/w/index.php?title=剑虻科&oldid=25607319” 分类：双翅目 隐藏分类： 本地相关图片与维基数据相同 含有英語的條目
