Thirdly, these flying males might glow to signal that they are
aposematically defended to nocturnal flying predators, such as bats or caprimulgids (Moosman et al.
Thus, they all keep so close together at all times as to have their bodies actually touching, and when travelling, move so slowly that the laziest snail might easily overtake and pass one of their bands, and even disappear beyond their limited horizon in a very short time." Obviously the naturalist was struck by the fact that these apparently defenseless young Chromacris made themselves so obvious to potential predators, a characteristic behavior of
aposematically colored animals.
Are juvenile grass snakes, Natrix natrix,
aposematically coloured?
Such
aposematically colored species may work as models in a Batesian Mimicry system where palatable prey species, which have converged in appearance to the model, gain a measure of protection from their predators by masquerading as the toxic model.
These moths are brightly,
aposematically colored, with shades of yellow, red, pink, orange, and white adorning their wings, and white, spotted heads, thoraxes, and abdomens--a coloration that advertises their demonstrated distastefulness to predators (Eisner & Eisner 1991).
Adults in Kerala, India are
aposematically colored with a black head, yellow tuberculate thorax, greenish forewings with yellow spots and a black and red-striped abdomen (Fig.
Zonocerus variegatus, like some other members of the family Pyrgomorphidae, is
aposematically coloured, sequesters toxic chemicals from plants, and commonly lives in dense groups (Chapman et al.
This result was true whether replicas were placed on natural or plain white backgrounds, suggesting that coral snake banded patterns function aposematically. In a separate experiment, replicas representing all six pattems of proposed coral mimics at the study site were attacked less often than unmarked brown replicas.
In fact, there is no direct evidence that coral snake patterns function aposematically or are avoided by visual predators in the wild (reviewed in Pough, 1988a).
Sequestration of phorbolesters by the
aposematically coloured bug Pachycoris klugii (Heteroptera: Scutelleridae) feeding on Jatropha curcas (Euphorbiaceae).
Both species are
aposematically colored and chemically defended with a metathoracic tracheal defense gland, and are the only grasshoppers known to possess this unique structure (Whitman et al.
