Clearwing butterflies challenge the thermal melanism hypothesis

The paper challenges the thermal melanism hypothesis by showing that transparent wings in Ithomiini butterflies are less efficient at absorbing light and heat, and that transparency increases with altitude, contrary to the hypothesis prediction.

Stay clear and dry! How microstructure diversity can offset the hydrophobicity costs of transparency in clearwing Lepidoptera

The paper investigates how wing microstructure in clearwing Lepidoptera compensates for reduced hydrophobicity in transparent patches, finding trade-offs between hydrophobicity and optical transparency.

Mimicry drives convergence in structural and light transmission features of transparent wings in Lepidoptera

This study shows that transparency in mimetic Lepidoptera is convergent among co-mimics, with micro- and nanostructures contributing to light transmission properties.

Ambient light and mimicry as drivers of wing transparency in Lepidoptera

The paper investigates how habitat openness, activity rhythm, and mimicry syndrome influence wing transparency in Lepidoptera, finding that diurnal species and those in open habitats exhibit higher light transmittance.

Transparency in butterflies and moths: structural diversity, optical properties and ecological relevance

This study examines transparency in 123 Lepidoptera species, revealing its structural basis, optical properties, and ecological relevance in thermoregulation and vision.

Distribution of iridescent colours in hummingbird communities results from the interplay between selection for camouflage and communication

This study examines color distribution in hummingbird communities, finding overdispersion in iridescent traits and clustering in dorsal patches, suggesting character displacement and cryptic coloration.

Hummingbird iridescence: an unsuspected structural diversity influences colouration at multiple scales

This study quantifies the structural and color diversity of iridescence in 36 hummingbird species, revealing unexpected structural complexity and its impact on coloration.

Transparency, a better camouflage than crypsis in cryptically coloured moths

The paper tests if transparency reduces detectability in cryptically coloured terrestrial prey by comparing survival rates of transparent, opaque, and wingless artificial moths in predation experiments.
