Shepton Mallet gardener discovers thriving colony of rare pink grasshoppers

A gardener from Shepton Mallet has made a remarkable discovery in her own backyard: a flourishing colony of scarce pink grasshoppers. Natasha Welch identified the unique insects, which display their striking colouration due to a hereditary mutation, and recorded her results before contacting the Somerset Wildlife Trust. What makes the discovery particularly noteworthy is that Welch has not only located individual pink grasshoppers, but has witnessed baby nymphs thriving in her garden—a development she describes as a “once-in-a-lifetime find”. The vibrant insects are typically seen and consumed by birds almost immediately, as their striking pink colour prevents them from camouflaging in their surroundings, making sightings of these unusual creatures extremely rare in the wild.

A remarkable find in the outdoor space

Welch first became aware of a lone pink grasshopper in her garden during 2025, but this year the situation has changed substantially. Walking through her wild grass, she finds numerous baby grasshoppers scattered throughout the vegetation. The gardener ascribes the colony’s survival to the protective environment her property provides. With four cats patrolling the grounds, birds are successfully prevented from entering the garden, taking away the main predator threat that usually decimates pink grasshopper populations shortly after their appearance.

Anne Halpin from the Somerset Wildlife Trust confirms that whilst the hereditary alteration creating pink colouration is not particularly rare in itself, the genuine finding of living pink grasshoppers remains remarkably exceptional. The mutation inhibits effective camouflage, leaving the insects vulnerable to predation. Halpin suggests that Welch’s overgrown grass and cat companions have established ideal conditions for the colony to flourish. She stresses that maintaining varied grass heights and varied plant life promotes grasshopper numbers, noting that “variety is the spice of life” when cultivating gardens that support wildlife.

• Birds regularly feed on pink grasshoppers on account of poor colour blending
• Four cats in the garden discourage birds from catching prey
• Uncut grass offers crucial shelter for grasshopper juveniles

Exploring the DNA alteration responsible for the colour

The distinctive pink colouration exhibited by the grasshoppers in Welch’s garden stems from a hereditary change that modifies the insects’ natural pigmentation. According to the Somerset Wildlife Trust, whilst this particular mutation is not especially uncommon at the DNA level, its visible manifestation in grasshoppers in the wild remains remarkably scarce. The mutation indicates a natural variation in the grasshopper population, yet one that holds considerable survival implications for impacted specimens. Scientists and naturalists consider such discoveries valuable for understanding genetic diversity within insect communities and the broader ecological factors that determine species survival odds.

Anne Halpin from the Somerset Wildlife Trust emphasises that the mutation itself takes place with some consistency within grasshopper populations, but the probability of observers actually encountering affected insects are extremely limited. Most pink grasshoppers perish before reaching maturity, their vivid appearance making them simple pickings for predatory birds. The circumstance that Welch’s garden has enabled the development of multiple pink grasshopper nymphs indicates a remarkable situation. Her property has effectively formed a refuge where this genetic mutation can endure and propagate, giving researchers and wildlife observers a exceptional possibility to observe these distinctive insects in their natural habitat.

Why pink grasshoppers rarely survive in the wild

The striking pink hue that gives these grasshoppers visually striking to human observers at the same time renders them extremely vulnerable to predation. Grasshoppers commonly use cryptic colouration—earthy greens and browns—to blend seamlessly into vegetation and soil, allowing them to hide from predators. Pink grasshoppers lack this vital camouflage advantage, standing out conspicuously against their surroundings. Birds, the primary predators of grasshoppers, swiftly locate these brightly coloured insects and consume them. This predatory pressure means that pink grasshoppers rarely survive long enough to reach reproductive maturity in standard garden and wild environments.

The remarkable circumstances in Welch’s Somerset garden have created a sheltered environment for these genetically unique insects. With four cats monitoring the property, songbirds are successfully deterred from entering the space where the grasshoppers prosper. Additionally, the long grass provides thick shelter and plentiful plant growth for the nymphs to shelter in. Without these safeguarding elements—the absence of avian predators and the abundance of long grass—pink grasshoppers would almost inevitably be discovered and eaten within days of hatching, making Welch’s successful community a truly exceptional natural occurrence.

Developing the perfect habitat for grasshopper thriving

Natasha Welch’s finding has unintentionally revealed how gardening approaches can profoundly influence wildlife populations. Her approach to maintaining her garden—allowing grass to remain long and maintaining a cat-dominated environment—has created ideal conditions for grasshoppers to flourish. Anne Halpin from Somerset Wildlife Trust emphasises that this outcome, whilst fortunate for the pink grasshoppers, is not accidental. Gardens that remain relatively unmown provide vital refuge, breeding grounds, and food sources for grasshoppers and countless other invertebrates. The long grass offers defence against predators whilst simultaneously sustaining varied plant species upon which grasshoppers rely for food.

For gardeners keen on promoting grasshopper populations, the principles are straightforward yet often overlooked in contemporary gardening. Rather than keeping the neatly trimmed grass traditionally favoured by British homeowners, allowing sections of grass to grow wild creates microhabitats where insects can thrive. The presence of Welch’s four cats, whilst not deliberately included in a conservation strategy, has proven instrumental in safeguarding the grasshoppers from bird attacks. This combination of factors—less frequent cutting, wild plant development, and limited bird access—has converted an ordinary Somerset garden into an remarkable sanctuary for these distinctive pink grasshoppers.

• Allow grass to grow tall in designated areas of your garden for protection
• Maintain a mixture of different grass heights to benefit various species
• Reduce pesticide use to preserve the insects grasshoppers rely on
• Plant varied plants including shrubs and wildflowers throughout your space
• Avoid heavy-handed gardening practices that damage grasshopper habitats

The role of habitat diversity in gardens

Anne Halpin promotes a more varied approach to landscape design, shifting beyond the monoculture of tightly mown lawns. She emphasises that grasshoppers, like the majority of wildlife, benefit enormously from habitat diversity. A garden incorporating a mixture of tall and short grass, interspersed with shrubs, trees, and wildflowers, gives grasshoppers multiple environmental spaces. Various plants supply varied food sources, protective cover, and reproduction sites. This ecological richness establishes a stable habitat where grasshoppers have access to everything necessary for survival and reproduction, regardless of seasonal changes or environmental pressures.

The principle of variety goes further than mere aesthetics; it constitutes a fundamental ecological principle that enhances the whole garden environment. Gardens with varied vegetation types support higher populations of insects, which subsequently attract birds and other wildlife. Halpin’s observation that “variety is the spice of life” captures this philosophy perfectly. By introducing varied plant varieties and maintaining varied grass heights, gardeners create conditions where grasshoppers and numerous other organisms can coexist successfully. Such gardens become self-supporting ecosystems where predator and prey interactions remain balanced, allowing even unusual genetic variations like pink grasshoppers to periodically survive and flourish.

Expert insights provided by Somerset Wildlife Trust

Anne Halpin from Somerset Wildlife Trust has offered crucial insights into the extraordinary find of pink grasshoppers flourishing in Welch’s garden. Whilst the genetic mutation responsible for the distinctive colouration of the insects is fairly common in nature, actually observing pink grasshoppers alive in the natural environment constitutes an exceptionally uncommon event. Halpin noted that grasshoppers remain inherently cryptic creatures, relying on camouflaging colouration to hide from predatory animals because they represent a food source for many bird species. The vivid pink colour severely compromises this defence strategy provided by nature, rendering survival in typical environments essentially unachievable. These insects are usually spotted and eaten by birds very quickly, rendering any sighting a authentic “once-in-a-lifetime find” for most observers.

The presence of several pink grasshoppers in Welch’s Somerset garden suggests that particular environmental conditions have created an exceptionally sheltered habitat. Halpin theorises that the four cats living there may be contributing substantially in deterring birds from accessing the garden, thereby lessening predation threats on the delicate pink grasshoppers. Additionally, Welch’s practice of letting grass to develop without intervention rather than maintaining a neatly trimmed lawn provides vital shelter and sustenance for grasshoppers. This combination of factors—fewer birds present and abundant natural vegetation—has apparently created conditions favourable enough for pink grasshoppers not only to survive but also to breed effectively, producing multiple juvenile grasshoppers throughout the warmer months.
