The Somerset Wildlife Trust says one of their supporters, Natasha Williams, has spotted an extraordinary pink grasshopper in her garden, capturing the attention of many wildlife enthusiasts.

This unusually coloured insect is the result of a rare genetic mutation known as erythrism, which affects pigmentation in animals similar to albinism and melanism.

Erythrism occurs when certain genes controlling colour are turned on or off, leading to the distinctive pink hue that makes these grasshoppers stand out from their typically green counterparts.

However, this vibrant colour can also make pink grasshoppers more susceptible to predators, such as birds, due to their lack of camouflage. This makes sightings of such insects incredibly rare and a 'once in a lifetime' experience.

The trust sayd Natasha's discovery highlights the fascinating aspects of genetic mutations in nature and the unexpected ways they can manifest in wildlife.
