Dittrich et al. (Proc. R. Soc. Lond. B 251, 195 (1993)) recently proposed that the existence of hoverfly species which are ‘imperfect’ mimics of wasps is a consequence of a constraint on the perceptual or learning mechanisms of birds. Here we put forward a new theory of the evolution of ‘imperfect mimics’. We propose that the apparent imperfection should be regarded as either true ambiguity, in which the vertebrate predator has difficulty in interpreting the meaning of two equally probable… 
The Dual Nature of Mimicry: Organismal Form and Beholder’s Eye
It is argued that the diversity of mimicry types is due to differences in variational properties of form-generating and perceptual systems among diverse groups of organisms and that these meaning-attributive processes underlie the functionality of mimicr.
Lepidopteran wing patterns and the evolution of satyric mimicry
It has now been found that eyespots and other designs on the wings of many insect species are often coupled with other wing patterns and designs that closely resemble heads and bodies of vertebrates and of various invertebrates.
Mimicry and Semiotic Evolution
The connection between mimicry and semiotic evolution is discussed, whereas the general focus of this book still lies in the structural aspects of mimicry and horizontal communicative processes therein.
The Evolution of Imperfect Mimicry
This chapter outlines the basic ideas of mimicry theory, and shows how they fail to account for the commonly imperfectly mimetic patterns of the main taxonomic group in the Holarctic that contains mimics; the hoverflies (Diptera, Syrphidae).
Insincere Flattery? Understanding the Evolution of Imperfect Deceptive Mimicry
A better understanding of the hypotheses and clarification of the distinctions or similarities between them is necessary, since each hypothesis makes very different assumptions, requiring different analytical approaches.
A comparative analysis of the evolution of imperfect mimicry
It is shown that the most plausible explanation is that predators impose less selection for mimetic fidelity on smaller hoverfly species because they are less profitable prey items, which supports the relaxed-selection hypothesis and rejects several key hypotheses for imperfect mimicry.
The evolution of imperfect mimicry
A simple signal detection model is used to show that the relationship between model--mimic similarity and mimic effectiveness is typically nonlinear, and predicts that if mimics spend an equal amount of time with each model species, then the optimal intermediate phenotype should more closely resemble the least numerous and least noxious model.
Imperfect Mimicry and the Limits of Natural Selection
It is found that the relaxed selection hypothesis has garnered the most support, and should provide critical insights into the limits of natural selection in producing complex adaptations.
The evolution of inaccurate mimics
It is shown here, however, that truly inaccurate mimicry of a single model organism may be favoured over perfect resemblance, by kin selection.
The evolution of imperfect mimicry in hoverflies
Hoverfly mimics fall into three major groups according to their models, involving bumblebees, honeybees and social wasps, with polymorphic and accurate forms being a key feature of mimics of the least noxious models, while highlyNoxious models have poor-quality mimicry.

As pigeon categorization and computer image analysis were both assessed by using colour slides designed for human vision, they lacked the natural colour information available to wild birds, in particular from ultraviolet (uv) wavelengths.
Imperfect mimicry: a pigeon’s perspective
P pigeons behave as if many hoverflies are indeed wasp mimics, however, they rank the two commonest hoverflies as very similar to wasps, despite these looking decidedly poor mimics to the human eye.
Warning Coloration and Mimicry
The purpose of this review is to provide a current analysis of warning coloration and mimicry to accompany the other discussions in this volume of the chemical ecology of insects. Recent literature

Aide memoire mimicry *
Animals and plants may gain protection by reminding would‐be aggressors of failure, or an unpleasant experience following an attempt at capture and ingestion, if the aggressor is forced to recall the attributes of such species, or the disagreeable sequela to a previous assault upon them.

Experimental results are presented, aimed at distinguishing between and disconvering what happens when there is mismatch with the neural signal channel, and when neural signals are processed inappropriately for the current situation.
