Host and parasitoid taxa encountered in rearings from the Zackenberg Valley.

Trophic levels separate hosts (trophic level 2) from parasitoids (trophic level 3) and hyperparasitoids (trophic level 4). Taxon-specific numbers in column “Code” identify taxa in Figs. 2, 4 and 5.aAs the larval characters of Boloria chariclea (Schneider, 1794) and Boloria polaris (Boisduval, 1828) are unknown, they have been combined as Boloria spp.bThe identity of Entephria taxa occurring at Zackenberg is currently being clarified by rearing and DNA sequencing techniques.

营养级（trophic level）将宿主（营养级2，trophic level 2）、寄生性天敌（parasitoid，营养级3）与重寄生天敌（hyperparasitoid，营养级4）区分开来。"Code"列中的分类单元（taxon）专属编号，用于标识图2、图4与图5中的各类分类单元。a) 因Boloria chariclea（Schneider, 1794）与Boloria polaris（Boisduval, 1828）的幼虫形态特征尚未明确，故将二者合并为Boloria spp.。b) 目前正通过饲养实验与DNA测序技术，对采自Zackenberg的Entephria属分类单元的物种身份进行厘清。
