Royal Society Open Science, 2021 To avoid predation, many animals mimic behaviours and/or coloration of dangerous prey. Here we examine potential sex-specific mimicry in the jumping spider Habronattus pyrrithrix.

Data for: Imperfect ant mimicry contributes to local adaptation in a jumping spider
, 2023 Putative ant mimicry is a remarkable example of an evolutionary strategy that can be well integrated into the framework of natural selection and adaptation.

Model aversiveness and the evolution of imperfect Batesian mimics. [PDF]
Behav Ecol, 2023 There are numerous examples of Batesian mimics that only imperfectly resemble their models. Given that inaccurate mimics are known to be predated more frequently than accurate ones, imperfect mimicry therefore poses something of a conundrum. One putative

Characterising the phenotypic diversity of Papilio dardanus wing patterns using an extensive museum collection. [PDF]
PLoS ONE, 2014 The history of 20th Century evolutionary biology can be followed through the study of mimetic butterflies. From the initial findings of discontinuous polymorphism through the debates regarding the evolution of mimicry and the step-size of evolutionary ...

Predation by avian predators may have initiated the evolution of myrmecomorph spiders
Scientific Reports, 2021 Myrmecomorphy is a strategy utilized by a variety of species, among which spiders are the most common. It is supposed that myrmecomorphy tends to be selected by predator avoidance of preying on ants rather than by blind ant workers.

How does viewing angle affect the perceived accuracy of Batesian mimicry in hoverflies? [PDF]
Behav EcolDespite Batesian mimicry often eliciting predator avoidance, many Batesian mimics, such as some species of hoverfly (Syrphidae), are considered to have an “imperfect” resemblance to their model.

The evolution of imperfect mimicry [PDF]
Behavioral Ecology, 2002 Examples of imperfect resemblance between Batesian mimics and their models appear widespread in the natural world, but so far few quantitative models have been proposed to explain the phenomenon. I used a simple signal detection model to show that the relationship between model--mimic similarity and mimic effectiveness is typically nonlinear.

THE EFFECT OF ALTERNATIVE PREY ON THE DYNAMICS OF IMPERFECT BATESIAN AND MÜLLERIAN MIMICRIES [PDF]
Evolution, 2004 Both Batesian and Müllerian mimicries are considered classical evidence of natural selection where predation pressure has, at times, created a striking similarity between unrelated prey species. Batesian mimicry, in which palatable mimics resemble unpalatable aposematic species, is parasitic and only beneficial to the mimics.

The functional significance of aposematic signals: geographic variation in the responses of widespread lizard predators to colourful invertebrate prey. [PDF]
PLoS ONE, 2014 Conspicuous colouration can evolve as a primary defence mechanism that advertises unprofitability and discourages predatory attacks. Geographic overlap is a primary determinant of whether individual predators encounter, and thus learn to avoid, such ...

From cues to signals: evolution of interspecific communication via aposematism and mimicry in a predator-prey system. [PDF]
PLoS ONE, 2014 Current theory suggests that many signaling systems evolved from preexisting cues. In aposematic systems, prey warning signals benefit both predator and prey. When the signal is highly beneficial, a third species often evolves to mimic the toxic species,
