European Journal of Entomology, 2009 The caterpillars of the butterfly Methona themisto (Nymphalidae: Ithomiinae) are conspicuously coloured and feed exclusively on Brunfelsia uniflora (Solanaceae), a plant that is rich in secondary plant substances, which suggests the caterpillars are ...

Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]
, 2007 We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

The impact of detoxification costs and predation risk on foraging : implications for mimicry dynamics [PDF]
, 2017 This work was supported by the European Research Council (Advanced Grant 250209 to Alasdair Houston), a Natural Environment Research Council Independent Research Fellowship (NE/L011921/1) awarded to A.D.H., a BBSRC-NERC project grant (BB/G00188X/1 ...

eLife, 2021 Müllerian mimicry is a positive interspecific interaction, whereby co-occurring defended prey species share a common aposematic signal. In Lepidoptera, aposematic species typically harbour conspicuous opaque wing colour patterns with convergent optical ...

Restoration Ecology, Volume 34, Issue 3, March 2026.Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

Increased predation of nutrient-enriched aposematic prey [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 Avian predators readily learn to associate the warning coloration of aposematic prey with the toxic effects of ingesting them, but they do not necessarily exclude aposematic prey from their diets. By eating aposematic prey ‘educated’ predators are thought to be trading-off the benefits of gaining nutrients with the costs of eating toxins ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 1, Page 39-57, January 2026.Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeling reveal that juveniles show a distinct UV‐enhanced white coloration that changes differently across sexes and body regions.

Endless forms most hidden: katydids that masquerade as moss [PDF]
, 2017 In the cloud forests of the central range of the Colombian Andes, we discovered a species of katydid (Orthoptera: Tettigoniidae) that imitates mosses to an uncanny degree and is exceedingly difficult to detect. The camouflage exhibited by this particular

Brightly coloured tissues in limid bivalves chemically deter predators [PDF]
Royal Society Open Science, 2019 Members of the marine bivalve family Limidae are known for their bright appearance. In this study, their colourful tissues were examined as a defence mechanism towards predators.

Shape of Evasive Prey Can Be an Important Cue That Triggers Learning in Avian Predators
Frontiers in Ecology and Evolution, 2022 Advertising escape ability could reduce predatory attacks. However, the effectiveness of certain phenotypic cues (e.g., color, shape, and size) in signaling evasiveness is still unknown. Understanding the role of such signals in driving predator learning
