Reexamining Sexual and Species Recognition in Butterflies: The Partner‐Hazard Space Framework

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Our review found no evidence that butterflies recognize the same sex or their own species. Behaviors previously interpreted as sexual or species recognition are indistinguishable from those interpreted as mate choice. Butterfly interactions can therefore be explained by assuming a sexual‐partner template that elicits mating behavior and a hazard ...

Departing With the Wind: Spring Migration Timing in Brent Geese From Their Most Important Staging and Wintering Site, the Wadden Sea World Heritage Site

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The timing of migratory departure reflects a balance between endogenous schedules and transient environmental opportunities. By linking GPS‐derived departure events with hourly atmospheric data, we demonstrate that wind assistance strongly increases departure probability in Brent Geese, while this selectivity weakens over time as migratory urgency ...

Eyespots in Automeris Moths Mimic Sympatric Owl Species (Lepidoptera: Saturniidae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Eyespot mimicry is a common anti‐predator strategy in moths, yet the mechanism underlying its effectiveness in Automeris remains unresolved. Using species distribution models, convolutional neural networks, and saliency mapping, we show that Automeris eyespots are visually confusable with sympatric owl eyes and that this similarity is concentrated in ...
