Aposematism is a phenomenon in which defended prey advertise their unprofitability to predators through conspicuous signals. Aposematic (warning) colouration is widespread across numerous insect orders but rarely occurs in insects that inhabit aquatic environments where conditions can impose constraints on visual signal transmission. In the semi-aquatic insect order Plecoptera (stoneflies), only the terrestrial adult stage of Austroperla cyrene (Austroperlidae) from New Zealand has been suggested to possess aposematic colouration, associated with the presence of hydrogen cyanide and documented unpalatability to predators. Here, we review evidence for the occurrence of aposematic colouration in Australian and South American Austroperlidae based on a synthesis of taxonomic literature and studies examining feeding preferences of predators in aquatic environments. Contrasting black, white and yellow colouration occurs commonly in adult Austroperlidae, and nymphs of several surveyed species were found to be aversive to predators, together suggesting that aposematism may be widespread in this family. The wider prevalence of aposematism in Austroperlidae should be examined further by directly testing the palatability of various species to predators and by analysing the chemical compositions of their defensive secretions. Austroperlid stoneflies offer new potential for understanding the evolution of aposematism in ecological and phylogenetic contexts that have not yet been explored.

南半球石蝇科(Plecoptera:Austroperlidae)中分离的证据

Aposematism 是一种现象,在这种现象中,受保护的猎物通过显眼的信号向捕食者宣传其无利可图。姿势性(警告)着色在许多昆虫纲中都很普遍,但是在居住于水生环境中的昆虫中很少发生,在这种环境中条件会限制视觉信号的传输。在半水生昆虫目 Plecoptera(石蝇)中,只有Austroperla cyrene的陆地成虫阶段来自新西兰的 (Austroperlidae) 被认为具有不规则的颜色,这与氰化氢的存在和记录的对捕食者的不适口性有关。在这里,我们根据分类学文献和检查水生环境中捕食者的摄食偏好的研究的综合,审查了澳大利亚和南美南美南翅目中发生显色着色的证据。对比黑、白和黄色的颜色在成年南翅目中很常见,并且发现几个被调查物种的若虫厌恶捕食者,共同表明该科中可能广泛存在无节食性。应通过直接测试各种物种对捕食者的适口性和分析其防御性分泌物的化学成分,进一步检查南翅目中更广泛流行的无节律性。Austroperlid 石蝇为理解尚未探索的生态和系统发育背景下的脱脂性进化提供了新的潜力。
