Bristol Study Finds Heliconius Butterflies Live 348 Days, Defying Age-Related Decline

Summary
Heliconius butterflies lived far longer than close relatives in a University of Bristol-led study, with Heliconius hewitsoni reaching 348 days versus 14 days for Dione juno.
Tests across butterfly houses, field recapture studies and insectary experiments showed the tribe had lower baseline mortality and slower aging, with Heliconius hecale showing little or no drop in grip strength with age.
Diet explained only part of the advantage: H. hecale maintained body mass and muscle function longer than non-pollen-feeding Dryas iulia, but still kept a substantial longevity edge even without pollen.
The findings point to both evolved biology and adult pollen-feeding as drivers of exceptional lifespan, positioning Heliconius as a new model for studying healthy aging in nature.
