Really excited to see @borreroja.bsky.social’s tour de force exploring the behavioural consequences of coordinated visual adaptations in *Heliconius*, and how these may break down in hybrids, out in the world. www.biorxiv.org/content/10.6...

¡Contento de compartir nuestro nuevo artículo sobre el forrajeo de polen en Heliconius himera en @behavecol.bsky.social! 🦋🌼 Exploramos cómo hembras y muchos de H. himera difieren en el forrajeo de polen y rasgos sensoriales. 1/6🧵👇https://academic.oup.com/beheco/article/37/3/arag014/8490681

Excited to share our new paper on pollen foraging in Heliconius himera @behavecol.bsky.social! 🦋🌼 academic.oup.com/beheco/artic... We explored how female and male H. himera differ in pollen foraging & sensory traits. 1/6🧵👇

Sexual dimorphism in pollen foraging and sensory traits in Heliconius butterflies

Male and female butterflies often face different ecological and sensory demands, yet how this shapes their foraging behaviour remains unclear. In Heliconiu

New paper out! A nice collaboration. We explore how olfactory brain structures and receptors evolved across this remarkable group, Heliconiini butterflies.

Evolution of the olfactory system during the radiation of Heliconiini butterflies

Abstract. Sensory system evolution plays a crucial role in shaping species’ interactions with their environment, yet the extent to which olfactory system d

José Borrero from Richard Merrill's lab studies how the visual acuity changes with age in different species of Heliconius butterflies and how it is related to brain morphology and neurogenesis. #dzg2025 @borreroja.bsky.social @dickmerrill.bsky.social

@borreroja.bsky.social shows how ecological divergence & post-eclosion brain dev shape visual performance in Heliconius butterflies. Speciation often related to transitions closed /open forest #ESEB2025 @tibbe-evolneuro.bsky.social @ebablab.bsky.social @alealisousa.bsky.social @r3rt0.bsky.social

🚨Anyone want a job?🚨 We have two #postdocs up for grabs! 🧪 - cell developmental biology/#evodevo/#neuroevodevo - bioinformatics and molecular biology Both working on brain evolution in Heliconiini butterflies Details below! Please repost 🙏 1/n

Just over a week left to apply for this. Please get the word out there and tell your students :)

Distinct evolutionary trajectories of two integration centres, the central complex and mushroom bodies, across Heliconiini butterflies

Neural circuits have evolved to produce cognitive processes that facilitate a species variable behavioural repertoire. Underlying this variation are evolutionary forces, such as selection, that operat...
