Chalkhill Blue: A Butterfly Under Threat
The chalkhill blue butterfly, known for its beauty across the UK’s grasslands, is facing new challenges. These butterflies have a unique symbiotic relationship with ants, where caterpillars provide honeydew in exchange for protection. However, their numbers are now declining due to changing environmental conditions.
Scientists have recently discovered a startling new feature of the chalkhill blue through a groundbreaking project called Psyche. This initiative aims to sequence the genomes of all butterflies and moths in Europe, revealing the intricate effects of climate change and habitat loss on these species.
The study revealed that the chalkhill blue’s chromosomes vary depending on their location. In southern Europe, they have 87 chromosomes, while in the north, they possess 90 chromosomes. This challenges the conventional belief that each species has a fixed number of chromosomes.
Evolutionary biologist Charlotte Wright from the Wellcome Sanger Institute describes this finding as intriguing. She explains that as glaciers retreated, the chalkhill blue added chromosomes progressively, an observation that sheds light on the butterfly’s evolutionary journey.
Evolution in Real-Time
Mark Blaxter, also from the Wellcome Sanger Institute, emphasized the significance of this discovery. He suggests that we are witnessing evolution in action as two species emerge from a single originator. This remarkable insight is a testament to the importance of genomic research.
The Psyche project collaborates with six leading European research centers, including Oulu University in Finland and the Institute of Evolutionary Biology in Barcelona. Named after the Greek goddess of the soul, Psyche aims to uncover the hidden stories of butterflies and moths.
Before modern genomics, the relationship between moths and butterflies sparked heated debates. Wright notes that DNA technology has clarified that butterflies are essentially a sub-group of moths, distinguished by their colorful appearance.
Butterflies and moths are crucial indicators of environmental health. Key points about their significance include:
- They are sensitive to changes in habitats and temperature.
- A tenth of all named species on Earth are moths or butterflies.
- Understanding their genomes helps us monitor environmental changes.
The Importance of Genomic Research
The discovery that the chalkhill blue butterfly has 87 to 90 chromosomes is striking compared to the 23 pairs humans have. However, large chromosome numbers are common among moths and butterflies, with some species possessing over 200 chromosomes.
Another fascinating example is the recently extinct xerces blue butterfly. By examining museum samples, scientists found that its genome revealed inbreeding, making it highly vulnerable. This research can guide efforts to protect other endangered species.
The Psyche project aims to identify similarly vulnerable species in Europe. Wright emphasizes that a genome is a perfect starting point to understand how well an organism is adapting to its environment.
Butterflies and moths play a vital role as pollinators and as a food source for birds. Their survival is crucial for maintaining ecological balance. Wright believes that this research, though fundamental, could have practical outcomes for conservation efforts.
Future of Butterfly Conservation
The findings from the Psyche project highlight the urgent need for conservation. By understanding the genetic makeup of butterflies and moths, scientists can develop strategies to protect them from the adverse effects of climate change and habitat loss.
Wright and her team at the Wellcome Sanger Institute are leading this effort, collaborating with experts across Europe. Their work is not just about preserving species but also about unraveling the mysteries of evolution.
With a tenth of all named species on Earth being moths or butterflies, their genomes hold valuable information about the health of our planet. The more we learn, the better equipped we are to tackle the challenges of environmental change.
In conclusion, the Psyche project is a beacon of hope for butterfly conservation. By shining a light on the genetic secrets of these delicate creatures, scientists are paving the way for a more resilient future for our natural world.

This is fascinating but also kind of depressing. Are there any immediate steps being taken to help these butterflies?

Lol, butterflies are moths in disguise! Who knew? 😂

Why aren’t more people talking about this? Seems like a huge deal for biodiversity.

How can we, as individuals, contribute to the conservation efforts mentioned in the study?

So interesting to see how climate change impacts even the smallest creatures. Thanks for sharing this!

Wait, did I read that right? Butterflies have over 200 chromosomes in some cases? That’s crazy!

This is mind-blowing! How do they even find out how many chromosomes butterflies have? 🦋
