Although mimetic animal coloration has been studied since Darwin's time, many questions
on the efficacy, evolution, and function of mimicry remain unanswered. Müller (1879) …

Many cryptic prey have also evolved hidden contrasting colour signals which are displayed
to would-be predators. Given that these hidden contrasting signals may confer additional …

Exaggerated eye span of stalk-eyed flies is a classic example of the evolution of an
extravagant male ornament resulting from sexual selection. Increased male eye span may …

Insect body color polyphenisms enhance survival by producing crypsis in diverse
backgrounds. While color polyphenisms are often indirectly induced by temperature, rearing …

Communication between rivals or potential mates is often accomplished with extremely
exaggerated ornaments and armaments in elaborate displays, and the evolution of such …

Holometabolous insects, like fruit flies, grow primarily during larval development. Scarce
larval feeding is common in nature and generates smaller adults. Despite the importance of …

Stalk-eyed flies are characterised by having eyes that project laterally from the head. Male
eyespan is known to be subject to sexual selection via female mate preference for …

Background Flies have some of the most elaborate visual systems in the Insecta, often
featuring large, sexually dimorphic eyes with specialized “bright zones” that may have a …

Host plant specialization by moths and butterflies has been a primary research focus in the
field of coevolution and ecological specialization. However, factors underlying the evolution …

Traits under divergent ecological selection that also function during mating can be important
in maintaining species boundaries. Few studies have considered mutual mate choice …
