Iceland has announced it is introducing a new friendly 'insect' treat to its shelves in the wake of the Colin the Caterpillar row.
The chain is launching Bonny the Butterfly cakes to promote the importance of biodiversity, and will donate profits to Butterfly Conservation.
It said its own caterpillar cake was previously removed from sale as it contained palm oil, and it had "no plans to re-enter the caterpillar category".
The news comes after TV wildlife expert Chris Packham called on supermarkets to use their cakes to raise awareness of the biodiversity crisis by moving away from caterpillars and focusing more on butterflies and moths.
In the natural world, caterpillars go through metamorphosis to turn into butterflies.
Richard Walker, managing director at Iceland Foods, said: "We had previously removed our caterpillar cake from sale as it contained palm oil and had no plans to re-enter the caterpillar category, even when the #FreeCuthbert movement captured the nation’s attention.
"However, when Chris called on supermarkets to use their cakes to raise awareness of the biodiversity crisis facing our planet, we had to get involved.
"I’m proud to say that our butterfly cakes will be completely palm oil free, in line with our commitment, and we’ll be supporting the important work of Butterfly Conservation by donating all proceeds from sales of this product."
The Bonny cakes are a soft sponge cake, topped with icing and a sugary butterfly slice. They will packaged in 100% recyclable materials, reports Wales Online.
Chris Packham said: "It's fantastic that Iceland have seized this opportunity to come to the assistance of Britain’s dwindling butterfly and moth populations, and of course their caterpillars."
Julie Williams, CEO of Butterfly Conservation, added: "We are absolutely delighted to learn that Iceland foods will be donating the profits of these environmentally-friendly butterfly cakes to the conservation of butterflies and moths in the UK.
"These amazing creatures are vital indicators of the health of our environment, supporting our birds and mammals, and the declines they face are worrying. This donation will help us continue our work to protect and conserve these creatures for future generations."
In the caterpillar cake world, Colin is the subject of a legal dispute between Marks & Spencer and the company Aldi, who sell rival character Cuthbert the Caterpillar.
Iceland said the butterfly cakes will be on sale in stores soon.
