Shepton Mallet gardener discovers thriving colony of rare pink grasshoppers

A gardener from Shepton Mallet has discovered a remarkable discovery in her own backyard: a flourishing colony of scarce pink grasshoppers. Natasha Welch identified the unique insects, which show their vivid colouration due to a genetic variation, and recorded her findings before contacting the Somerset Wildlife Trust. What makes the discovery especially significant is that Welch has not only found individual pink grasshoppers, but has documented baby nymphs developing in her garden—a development she describes as a “once-in-a-lifetime find”. The striking insects are usually observed and eaten by birds almost immediately, as their eye-catching pink hue prevents them from merging with their surroundings, making observations of these rare insects exceptionally uncommon in the wild.

A surprising find in the backyard

Welch initially spotted a lone pink grasshopper in her garden in 2025, but this year the situation has shifted significantly. Walking through her unmown grass, she finds numerous baby grasshoppers distributed across the vegetation. The gardener ascribes the colony’s survival to the protective environment her property provides. With four cats roaming the grounds, birds are effectively deterred from entering the garden, taking away the main predator threat that usually wipes out pink grasshopper populations shortly after their appearance.

Anne Halpin from the Somerset Wildlife Trust confirms that whilst the genetic mutation creating pink colouration is not particularly rare in itself, the actual discovery of pink grasshoppers in the wild remains remarkably exceptional. The mutation inhibits successful concealment, rendering the insects vulnerable to predation. Halpin proposes that Welch’s unkempt lawn and cat companions have created ideal conditions for the colony to thrive. She emphasises that keeping grass at different lengths and diverse vegetation promotes grasshopper numbers, noting that “variety is the spice of life” when cultivating wildlife-friendly gardens.

• Birds commonly consume pink grasshoppers due to poor concealment
• Four cats in the garden keep birds away from hunting
• Uncut grass offers crucial environment for grasshopper nymphs

Examining the genetic mutation responsible for the hue

The distinctive pink colouration displayed by the grasshoppers in Welch’s garden stems from a genetic mutation that affects the insects’ inherent coloration. According to the Somerset Wildlife Trust, whilst this particular mutation is not especially uncommon at the genetic level, its visible manifestation in grasshoppers in the wild remains remarkably scarce. The mutation represents a inherent diversity in the grasshopper population, yet one that holds considerable ecological consequences for impacted specimens. Scientists and naturalists consider such discoveries important in comprehending hereditary variation within insect communities and the broader ecological factors that influence species survival rates.

Anne Halpin from the Somerset Wildlife Trust stresses that the mutation itself takes place with some consistency within grasshopper populations, but the likelihood of people actually spotting affected insects are very small. Most pink grasshoppers die before they mature, their vibrant colouration making them simple pickings for hunting birds. The fact that Welch’s garden has fostered the production of multiple pink grasshopper nymphs constitutes an unusual occurrence. Her property has effectively established a haven where this genetic variation can endure and propagate, offering researchers and wildlife enthusiasts a exceptional possibility to observe these distinctive insects in the wild.

Why pink-coloured grasshoppers rarely survive in the wild

The brilliant pink hue that makes these grasshoppers visually striking to human observers at the same time renders them highly susceptible to predation. Grasshoppers typically rely on cryptic colouration—muted greens and browns—to blend seamlessly into vegetation and soil, enabling them to conceal themselves from predators. Pink grasshoppers lack this essential camouflage advantage, appearing strikingly obvious against their surroundings. Birds, the main hunters of grasshoppers, rapidly identify these brightly coloured insects and consume them. This predatory pressure means that pink grasshoppers rarely survive long enough to attain breeding age in standard garden and wild environments.

The exceptional circumstances in Welch’s Somerset garden have established a safe haven for these genetically unusual insects. With four cats monitoring the property, songbirds are successfully deterred from entering the space where the grasshoppers flourish. Additionally, the long grass provides thick shelter and rich foliage for the nymphs to hide within. Without these defensive conditions—the lack of bird predators and the presence of tall grass—pink grasshoppers would very likely be located and preyed upon within days of hatching, making Welch’s flourishing population a truly exceptional natural occurrence.

Establishing the perfect conditions for grasshopper survival

Natasha Welch’s discovery has inadvertently demonstrated how gardening approaches can profoundly influence wildlife populations. Her approach to caring for her outdoor space—allowing grass to grow tall and maintaining a cat-dominated environment—has created ideal conditions for grasshoppers to flourish. Anne Halpin from Somerset Wildlife Trust highlights that this outcome, whilst beneficial to 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 tall vegetation offers protection from predators whilst simultaneously supporting the diverse plant life upon which grasshoppers depend for sustenance.

For gardeners interested in supporting grasshopper populations, the principles are simple but frequently neglected in modern horticultural practice. Rather than maintaining the manicured lawns conventionally preferred by British homeowners, allowing sections of grass to grow wild creates microhabitats where insects can flourish. The presence of Welch’s four cats, whilst not deliberately included in a conservation strategy, has proven instrumental in protecting the grasshoppers from avian predation. This combination of factors—less frequent cutting, wild plant development, and restricted avian presence—has converted an ordinary Somerset garden into an exceptional refuge for these distinctive pink grasshoppers.

• Allow grass to grow tall in designated areas of your garden for shelter
• Keep a mixture of different grass heights to benefit various species
• Reduce pesticide use to preserve the insects grasshoppers rely on
• Plant diverse vegetation including shrubs, wildflowers and native plants throughout your garden
• Avoid intensive garden management practices that disrupt grasshopper habitats

The significance of diverse garden habitats

Anne Halpin promotes a more diverse approach to garden design, departing from the monoculture of tightly mown lawns. She highlights that grasshoppers, like the majority of wildlife, derive considerable advantage from habitat diversity. A garden containing a mixture of tall and short grass, interwoven with shrubs, trees, and wildflowers, gives grasshoppers multiple habitats. Diverse vegetation offer different food options, shelter options, and reproduction sites. This plant variety forms a resilient ecosystem where grasshoppers are able to locate everything required for survival and reproduction, irrespective of seasonal changes or environmental pressures.

The principle of variety extends beyond mere aesthetics; it represents a fundamental ecological principle that benefits the entire garden ecosystem. Gardens with varied vegetation types support higher populations of insects, which in turn attract birds and other wildlife. Halpin’s observation that “variety is the spice of life” encapsulates this approach perfectly. By incorporating different vegetation types and maintaining differing grass lengths, gardeners create conditions where grasshoppers and countless other species can coexist successfully. Such gardens develop into self-supporting ecosystems where natural predator-prey relationships stay in equilibrium, allowing even unusual genetic variations like pink grasshoppers to periodically survive and thrive.

Professional perspectives from Somerset Wildlife Trust

Anne Halpin from Somerset Wildlife Trust has provided crucial insights into the extraordinary find of grasshoppers with pink colouration flourishing in the garden of Welch. Whilst the genetic mutation that causes the distinctive colouration of the insects is not particularly uncommon in the natural world, actually observing pink grasshoppers alive in the wild constitutes an extraordinarily rare occurrence. Halpin explained that grasshoppers are naturally secretive insects, relying on camouflaging colouration to evade predators because they represent a food source for many bird species. The bright pink colouration greatly undermines this defence strategy provided by nature, making survival in typical environments essentially unachievable. These creatures are usually spotted and consumed by avian predators very quickly, making any observation a authentic “once-in-a-lifetime find” for most observers.

The occurrence of several pink grasshoppers in Welch’s garden in Somerset suggests that specific environmental factors have established an unusually protective 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 habit of allowing grass to grow naturally rather than maintaining a neatly trimmed lawn offers essential shelter and food sources for grasshoppers. This mix of conditions—reduced bird activity and plentiful wild plants—has apparently created conditions favourable enough for pink grasshoppers not merely to survive but to breed effectively, producing multiple juvenile grasshoppers throughout the growing season.
