Moreover, as in other cases of aposematism (Cott, 1940; Wickler, 1968;
There is significant evidence to support the predators as being potential selective agents in the evolution and/or maintenance of aposematism in Oncopeltus, thus supporting the efficacy of automimicry.
It should be expected that aposematic individuals would have slower escape behaviors than cryptic ones in order to maximize the effectiveness of aposematism (Jackson et at.
In well-studied species such as Schistocerca emarginata, gregariousness and aposematism are related to the feeding of nymphs on plants that confer gut-content mediated toxicity to predators (Sword et al.
Edmunds (1991) argued that one or both types of mimicry frequently occur in similarly colored nudibranch species, suggesting that this seems to be the strongest support for aposematism in this group of molluscs, because the widespread occurrence of mimicry in those species is almost impossible to explain unless some of them are aposematic.

1985), such as aposematism, threat displays, gregariousness, flightlessness, sluggishness, and large size.
Evidence why Oreina and also the sister genus Chrysolina are more flexible in their host affiliations is still missing, yet it is tempting to speculate that the combination of autogenously produced defensive chemistry and aposematism frees the beetles of possible constraints imposed by host plant-dependent crypsis or dependence on defensive plant compounds (as is possibly the case in Phyllobrotica and certainly in Tetraopes, B.
The energetic hydromechanical signal also may frighten predators because of the apparent large size and strength, a form of aposematism.
Rosenberg (1989) argued that aposematism in marine gastropods cannot evolve by kin selection because they have pelagic larvae and thus disperse randomly over wide areas, minimizing the probability that kin settle close to each other.
In the study, aposematism was used as a cue for unpalatability, and the result is in accordance with the expectation that in insects gregariousness should evolve in unpalatable species (Sillen-Tullberg and Leimar 1988).
