Additional Adaptations Against Predation

摘要: As butterflies, monarchs (Danaus plexippus) (Fig. 7.1) do not fight predators or act passively if an attack by a predator is imminent; instead, the monarch uses warning coloration and chemical defenses against predation. adults, are brightly colored in orange, black, white; they, therefore, stand out environment to predator, much like pattern of poisonous coral snake (Micrurus fulvius) (Zug et al. 2001). What does signal potential predator? That unpalatable, so stay away. Monarch becomes unpalatable because toxins that larvae feed upon milkweed (Asclepias syriaca). These cardio glycosides, which elicits vomiting birds may them. Only two bird species, black-headed oriole (Icterus abeillei) grosbeak (Pheucticus melanocephalus) known on with no ill effect. In fact, viceroy butterfly (Limenitis archippus) mimics offset predation it, form mimicry as Batesian.
