What to know about Tropical butterflies 'hedge bets' on reproduction as extreme seasons reshape Amazon life

Researchers from Queen Mary University of London and other institutions studied reproductive plasticity in brush-footed butterflies in the Peruvian Amazon. The study found that different species employ varying strategies, such as reproductive diapause, to adapt to seasonal temperature and rainfall changes.

Claim 1: “The researchers focused on two butterfly species in the genus Catonephele and found that while both species reduced egg production during the dry season, only one of the species underwent a reproductive diapause”
CORROBORATED
Multiple web search results (bioRxiv and others) explicitly state that analyses of two Catonephele species revealed a shared temperature response but that dry season diapause occurred only in C. acontius.
