Cover Story: Habitat loss shapes animal behaviour, impacting the long-term survival of species. In our study, we explored the connection between the flight abilities of the woodland-specialist butterfly Limenitis camilla and the spatial–temporal connectivity of its primary habitat: broadleaved forests. We assessed shifts in forest functional connectivity in Wallonia, Belgium, over recent decades using land-cover data. Furthermore, we selectively captured L. camilla females in areas representing opposite ends of habitat connectivity and monitored their behaviours within outdoor arenas designed to replicate the species' natural habitat. Our findings reveal that butterflies from fragmented forests exhibit an increase in departure-related behaviour, potentially indicating an evolutionary adaptation for locating suitable egg-laying sites in shrinking, isolated habitats.

Chitin is the major component of the extracellular cuticle and plays multiple roles in insects. In butterflies, chitin builds wing scales for structural colors. Here, we show that intracellular chitin in live cells can be detected in vivo with fluore...
