Keep an eye out for the elusive Jersey Tiger moths in local parks and gardens

The Big Butterfly Count, a national wildlife survey organised by the charity Butterfly Conservation, is providing valuable insights into the changing distribution of wildlife in the UK. This year, the count has seen a significant increase in Jersey Tiger moth sightings, with 5,300 moths recorded mid-way through the summer compared to 3,496 last year[1][4].

This marks a 78% rise from 2024, and the Jersey Tiger moths, once largely restricted to the Channel Islands, the south coast of England, London, and south-east Wales, are now frequently spotted across southern England and are continuing to spread through East Anglia and into the Midlands[1].

Experts attribute this surge to the warm, dry conditions, which have enabled the moth to expand from its historical range[1][2]. The warmer climate extends their habitat suitability and benefits their survival and reproduction, explaining the significant population rise.

However, the story for many butterfly species is not as positive. Damage to habitats, climate change, and the use of pesticides are contributing factors to the decline of butterfly species[5]. More than 80% of butterfly species have declined since the 1970s[5].

Dr. Richard Fox, the head of science at Butterfly Conservation, has stated that one good year cannot undo the long-term decline many species are facing[6]. He emphasises the importance of public participation in the Big Butterfly Count, stating that the more people who take part, the more we can learn about how species are adapting or struggling in the face of climate change and extreme weather[6].

The Big Butterfly Count matters because the data collected by the public directly informs national conservation strategies and helps protect not just butterflies and moths, but the wider ecosystems they support[1]. This year, the charity is urging people to take part in a "nationwide rescue mission" for the UK's ailing butterfly species[7].

The Jersey Tiger moths are recognisable by their black and white tiger stripe forewings and vibrant red-orange or yellow hindwings adorned with bold black spots[3]. If you spot one of these exotic-looking creatures in your garden, parks, or countryside, Butterfly Conservation encourages you to record your sighting as part of the Big Butterfly Count[2].

The annual butterfly count is currently underway until August 10[1]. By taking part, you can contribute to tracking the changes in wildlife distribution and support conservation efforts for these fascinating creatures.

8. The surge in Jersey Tiger moth sightings during the Big Butterfly Count might suggest a positive impact of environmental science, like warmer climate and suitable habitats, but it's crucial to remember that many butterfly species are still struggling, possibly due to factors such as climate change, habitat damage, and pesticide usage in the field of agricultural science.
9. As the Jersey Tiger moths continue to spread from their historical range into new areas like East Anglia and the Midlands, it's essential for homeowners to create butterfly-friendly gardens, taking care to provide suitable plants, water sources, and reducing pesticide use to support a variety of these intriguing insects.
10. Our lifestyle choices in home and garden, including gardening practices, can have a significant impact on the wellbeing of butterflies and other wildlife, which is why it's vital to participate in initiatives like the Big Butterfly Count, as the data collected not only informs conservation strategies for butterflies but also aids in understanding how the wider environment is affected by climate change and other factors.
