What can butterflies and moths teach us about conserving nature on a warming planet?

Dr. Callum Macgregor in the field.

View this interesting presentation by Callum Macgregor from the University of Hull as he discusses what we know and suspect about the impact of climate change on butterflies and moths. Callum’s talk was part of the Thomas C Emmel seminar series on Expanding Horizons in Leidoptera Research at the Florida Museum’s McGuire Center for Lepidoptera and Biodiversity, March 30, 2021.

Much of the discussion centers around whether univoltine or multi-voltine butterfly species are more likely to adapt to a warming climate, and what tradeoffs may be made by butterflies that adapt to global warming by advancing their phenology in the spring (i.e., emerging earlier). The issue, Macgregor suggests, is not straightforward.

Much of his work is also captured in this open-access article in Nature Communications (2019). His subsequent work on the UK’s Speckled Wood published in PeerJ (2021) focuses on morphological changes in response to climate change by this widespread British butterfly.
