Soral Crypsis: Protective Mimicry of a Coccid on an Indian Fern
Journal of Integrative Plant Biology, 2008Abstract Herbivory with crypsis is not well documented in ferns. The present record of cryptic coloration of coccid Saissetia filicum Boisduval (Homoptera: Coccidae) to the sori of a fern species Asplenium nidus L. (Aspleniaceae) is unique. Predatory beetles (Jauravia sp., Coleoptera: Coccinellidae) that feed on the coccids, are suggested to be ...

Evolution of crypsis in feather lice
2012Crypsis is the color resemblance of an animal to its background such that predators have difficulty in distinguishing it. Although a great deal is known about crypsis in free-ranging insects, crypsis in ectoparasites is still poorly understood. Among ectoparasites, feather lice provide a unique chance to test whether ectoparasites are cryptically ...

Frequency-dependent predation, crypsis and aposematic coloration
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1988Abstract Frequency-dependent predation may maintain or prevent colour pattern polymorphisms in prey, and can be caused by a variety of biological phenomena, including perceptual processes (search images), optimal foraging and learning.

Crypsis and Behaviour in Sandhoppers: Antipredator Effectiveness in the Water
Ethology, 1997AbstractPredation experiments in tanks with the two‐banded bream fish Diplodus vulgaris and the sandhopper Talitrus saltator demonstrated that: 1. some specific behaviours; and 2. crypsis of the back have an antipredator function. They reduced by one‐half the predatory attacks in the water, under artificial conditions.
