Shepton Mallet gardener discovers thriving colony of rare pink grasshoppers

A gardener from Shepton Mallet has discovered a striking discovery in her own backyard: a thriving colony of rare pink grasshoppers. Natasha Welch observed the distinctive insects, which display their vivid colouration due to a genetic variation, and recorded her results 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 thriving in her garden—a development she describes as a “once-in-a-lifetime find”. The striking insects are typically seen and preyed upon by birds almost immediately, as their distinctive pink appearance prevents them from merging with their surroundings, making observations of these rare insects remarkably infrequent in the wild.

A surprising find in the backyard

Welch first observed a lone pink grasshopper in her garden during 2025, but this year the situation has shifted significantly. Walking through her unmown grass, she finds numerous baby grasshoppers scattered throughout the vegetation. The gardener ascribes the colony’s survival to the safe conditions her property offers. With four cats patrolling the grounds, birds are successfully prevented from entering the garden, taking away the principal threat that usually destroys pink grasshopper populations shortly after their appearance.

Anne Halpin from the Somerset Wildlife Trust confirms that whilst the hereditary alteration producing pink colouration is not especially uncommon 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 suggests that Welch’s overgrown grass and feline guardians have established optimal circumstances for the colony to thrive. She stresses that maintaining varied grass heights and varied plant life encourages grasshopper populations, noting that “variety is the spice of life” when creating wildlife-friendly gardens.

• Four cats in the garden keep birds away from catching prey
• Long grass supplies vital shelter for grasshopper juveniles

Examining the hereditary variation responsible for the colour

The remarkable pink colouration seen in the grasshoppers in Welch’s garden originates from a genetic mutation that alters the insects’ inherent coloration. According to the Somerset Wildlife Trust, whilst this specific genetic variation is not especially uncommon at the genetic level, its observable appearance in grasshoppers in the wild remains exceptionally uncommon. The mutation constitutes a inherent diversity in the grasshopper population, yet one that holds considerable survival implications for impacted specimens. Scientists and naturalists consider such discoveries valuable for comprehending hereditary variation within insect communities and the broader ecological factors that affect how species survive.

Anne Halpin from the Somerset Wildlife Trust stresses that the mutation itself happens fairly regularly within grasshopper populations, but the probability of observers actually encountering affected insects are extremely limited. Most pink grasshoppers fail to survive to adulthood, their bright colouring making them simple pickings for bird predators. The circumstance that Welch’s garden has enabled the emergence of several pink grasshopper nymphs constitutes an unusual occurrence. Her property has effectively formed a haven where this genetic variation can persist and reproduce, offering researchers and wildlife enthusiasts a rare opportunity to examine these remarkable creatures in the wild.

Why pink-coloured grasshoppers seldom endure in the wild

The brilliant pink hue that gives these grasshoppers notably conspicuous to human observers at the same time renders them extremely vulnerable to predation. Grasshoppers commonly use cryptic colouration—earthy greens and browns—to merge effortlessly with vegetation and soil, enabling them to conceal themselves from predators. Pink grasshoppers are without this crucial camouflage advantage, standing out conspicuously against their surroundings. Birds, the main hunters of grasshoppers, swiftly locate these brightly coloured insects and consume them. This hunting pressure means that pink grasshoppers rarely survive long enough to reach reproductive maturity in typical garden or wild environments.

The outstanding circumstances in Welch’s Somerset garden have established a protective bubble for these genetically unique insects. With four cats monitoring the property, songbirds are effectively discouraged from entering the space where the grasshoppers thrive. Additionally, the unmown grass provides thick shelter and abundant vegetation for the nymphs to hide within. Without these protective factors—the absence of avian predators and the abundance of long grass—pink grasshoppers would almost inevitably be located and preyed upon within days of hatching, making Welch’s thriving colony a genuinely remarkable natural occurrence.

Developing the perfect habitat for grasshopper thriving

Natasha Welch’s finding has unintentionally revealed how garden management practices can profoundly influence wildlife populations. Her approach to caring for her outdoor space—allowing grass to grow tall and keeping cats that deter birds—has established perfect circumstances for grasshoppers to thrive. Anne Halpin from Somerset Wildlife Trust highlights 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 supporting the diverse plant life upon which grasshoppers rely for food.

For gardeners keen on supporting grasshopper populations, the principles are simple but frequently neglected in contemporary gardening. Rather than keeping the neatly trimmed grass conventionally preferred by British homeowners, letting areas of grass develop naturally creates microhabitats where insects can thrive. The presence of Welch’s four cats, whilst not intentionally part of a conservation strategy, has proven instrumental in protecting the grasshoppers from bird attacks. This combination of factors—less frequent cutting, natural vegetation growth, and restricted avian presence—has converted an ordinary Somerset garden into an exceptional refuge for these remarkable pink insects.

• Allow grass to reach full height in designated areas of your garden for shelter
• Maintain a mixture of different grass heights to benefit various species
• Minimise pesticide use to protect the insects grasshoppers rely on
• Plant varied plants including shrubs and wildflowers throughout your space
• Avoid heavy-handed gardening practices that disrupt grasshopper habitats

The significance of habitat diversity in gardens

Anne Halpin promotes a more multifaceted approach to landscape design, shifting beyond the monoculture of short-cut lawns. She emphasises that grasshoppers, like the majority of wildlife, gain substantially from habitat diversity. A garden incorporating a combination of tall and short grass, interwoven with shrubs, trees, and wildflowers, gives grasshoppers multiple ecological niches. Different plant species provide varied food sources, shelter options, and reproduction sites. This ecological richness establishes a robust environment where grasshoppers can find everything required for survival and reproduction, independent of seasonal changes or environmental pressures.

The principle of diversity extends beyond mere aesthetics; it constitutes a core ecological concept that benefits the whole garden environment. Gardens with varied vegetation types support higher populations of insects, which in turn draw in birds and other wildlife. Halpin’s observation that “variety is the spice of life” captures this philosophy perfectly. By incorporating varied plant varieties and keeping varied grass heights, gardeners create conditions where grasshoppers and countless other species can coexist successfully. Such gardens become self-sustaining habitats where predator and prey interactions remain balanced, enabling even rare genetic traits like pink grasshoppers to periodically survive and thrive.

Specialist knowledge from Somerset Wildlife Trust

Anne Halpin from the Somerset Wildlife Trust has provided crucial insights into the extraordinary find of grasshoppers with pink colouration thriving in the garden of Welch. Whilst the genetic mutation responsible for the distinctive colouration of the insects is fairly common in the natural world, genuinely spotting pink grasshoppers alive in the natural environment constitutes an exceptionally uncommon event. Halpin noted that grasshoppers remain naturally secretive insects, depending on camouflaging colouration to hide from predators because they constitute 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 eaten by avian predators very quickly, making any observation a authentic “once-in-a-lifetime find” for most observers.

The presence of several pink grasshoppers in Welch’s garden in Somerset suggests that specific environmental factors have established an exceptionally sheltered habitat. Halpin theorises that the four resident cats may be contributing substantially in keeping birds away from accessing the garden, thereby reducing predation pressure on the vulnerable pink insects. Additionally, Welch’s habit of allowing grass to develop without intervention rather than maintaining a neatly trimmed lawn provides essential shelter and food sources for grasshoppers. This combination of factors—reduced bird activity and abundant natural vegetation—has apparently created conditions favourable enough for pink grasshoppers not only to survive but also to reproduce successfully, producing multiple nymphs or baby grasshoppers throughout the warmer months.
