Pupal Warning Coloration of Three Species of Cystidia (Lepidoptera: Geometridae: Ennominae) in Relation to Their Pupation Sites

open access: yesInsects, 2022
Many insects display a cryptic color to avoid detection by predators that search for prey by sight. However, some species with chemicals that predators dislike may display a warning color (aposematism) to predators.

Beta diversity of Arctiinae moths (Lepidoptera: Erebidae) along a recovering tropical forest gradient

open access: yesJournal of Animal Ecology, EarlyView.
Using novel approaches of Hill‐number based and coverage‐standardized dissimilarity metrics and community‐weighted traits, we show that tiger moth communities exhibit various traits prone to land‐use intensity and undergo a complex and non‐linear response to tropical rainforest recovery, corroborating recent findings on biotic differentiation (Keck et ...

Data from: Multiple origins of sexual dichromatism and aposematism within large carpenter bees

open access: yes, 2018
The evolution of reversed sexual dichromatism and aposematic coloration have long been of interest to both theoreticians and empiricists. Yet despite the potential connections between these phenomena, they have seldom been jointly studied.

Dorsal Crypsis and Chemical Defense Jointly Shape Brain Size in Toads

open access: yesIntegrative Zoology, EarlyView.
We found that total brain size and dorsal crypsis under both ultraviolet‐sensitive (UVS) and violet‐sensitive (VS) tetrachromatic bird visual models were negatively associated across eight species of toads. Our findings suggest that when species reduce predation risk by evolving increased dorsal crypsis, they may exhibit decreased brain size due to ...

Chemical defence of the warningly coloured caterpillars of Methona themisto (Lepidoptera: Nymphalidae: Ithomiinae)

open access: yesEuropean 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 ...

The dual benefits of aposematism: predator avoidance and enhanced resource collection

open access: yes, 2009
Theories of aposematism often focus on the idea that warning displays evolve because they work as effective signals to predators. Here, we argue that aposematism may instead evolve because, by enhancing protection, it enables animals to become more ...

Gall Apparency Drives Parasitoid Richness in a Highly Specialised Gall‐Parasitoid Food Web From a Tropical Rainforest

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
We present the largest tropical tri‐trophic plant–gall–parasitoid network documented to date, assembled from lowland rainforest in Papua New Guinea. The network reveals strikingly high specialisation, in addition to gall traits such as apparency shaping parasitoid richness.

Red coloration and the evolution of aposematism in arboreal sciurids

open access: yes, 2022
An animal's coloration is associated with a variety of processes and is therefore subjected to multiple selective pressures. Mammals, especially, are typically inconspicuously colored, or cryptic, to avoid detection by predators. Alternatively, an animal

Precipitation shapes colour polymorphism in a widespread spider

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3176-3189, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Colour polymorphism, the presence of multiple colour variants within a population, is a common example of intraspecific phenotypic variation and has served as a model for studying drivers of diversity.

Fearful symmetry in aposematic plants [PDF]

open access: yesPlant Signaling & Behavior, 2011
Symmetry has been proposed to increase the efficiency of visual aposematic displays in animals, and I suggest that it may also be true for many aposematic spiny or poisonous plants. For instance, in the very spiny plant taxa cacti, Aloe sp., Agave sp.
