These insect-themed treats have become party staples over the years

M&S’s Colin the caterpillar cake has become somewhat of a British institution since it first went on sale 30 years ago.

The chocolatey treat is a failsafe for all ages and occasions, from kids’ and adults’ birthday parties (David Beckham and Dame Judi Dench are big fans), to farewell work dos.

In fact, it’s proved so popular with cake fans that M&S has launched an entire range of spin-offs: Colin got himself a girlfriend back in 2016 and has since branched out into mini rolls, wedding cakes and seasonal versions for events like Halloween, Christmas, Easter and Mother’s Day.

But trouble has been brewing for Colin in recent weeks as its status as the go-to caterpillar cake has come under threat from a bevy of imitators, including Aldi.

This week, M&S launched legal action against the budget retailer, claiming that its cake – called Cuthbert – infringes on Colin’s trademark. The company claims that the similarities between its cake and Aldi’s could lead consumers to believe they are of the same standard.

However, Aldi isn’t the only supermarket to have cottoned on to the celebrity caterpillar’s popularity. A whole host of other grocers have designed their own versions, albeit with different names: there’s Tesco’s Curly, Waitrose’s Cecil, Asda’s Clyde and Morrison’s Morris, to name a few.

M&S Colin the caterpillar: £7,

The OG caterpillar cake, Colin is made from a creamy chocolate sponge roll that’s filled with chocolate buttercream. It features a series of distinctive curves – which make it all the easier to cut 10 equal portions – and is covered in a milk chocolate shell.

It also has a decorative face made from solid white chocolate, which features milk chocolate eyes and a pink tongue, while its feet are also made from white chocolate. The cake is finished with a sprinkle of sugar-coated milk chocolate beans all over its back.
