Abstract

A large diversity of saproxylic Empidoidea from a temperate deciduous forest in southern Quebec is documented. Adults of 43 empidoid species representing 19 genera in 12 subfamilies and three families were collected from in situ sealed emergence traps placed over decayed logs of American beech (Fagus grandifolia Ehrhart) and sugar maple (Acer saccharum Marshall). The results of this technique give a clear indication of the saproxylic larval and pupal habitat of these species. The importance of Empidoidea as larval predators in decayed wood niches is noted.

摘要

记录了魁北克南部温带落叶林中种类繁多的食木虻总科昆虫。从放置在美国山毛榉（Fagus grandifolia Ehrhart）和糖枫（Acer saccharum Marshall）腐朽原木上的原位密封羽化诱捕器中收集到了43种食木虻总科昆虫的成虫，它们分属于12个亚科、3个科的19个属。这项技术的结果清楚地表明了这些物种的食木幼虫和蛹的栖息地。文中指出了食木虻总科昆虫作为腐朽木生态位中幼虫捕食者的重要性。
