Butterfly theme for this year's city arts festival

The two-day Peterborough Celebrates festival will take place on 17 and 18 May

A city festival of culture and diversity will return this year with the theme "flutter of butterflies", in support of nature.

Peterborough Celebrates, a free two-day event, will be held at Ferry Meadows on 17 and 18 May, organised by the Nene Park Trust (NPT).

This year, festival organisers have invited schools, community groups and individuals to take part in a special display to be showcased at the venue.

Colourful butterflies will be created with recycled plastic bottles and paint with participants free to chose their pattern and shape.

NPT is holding a drop-in workshop at Ferry Meadows on 11 April to guide participants on how the butterflies can be created.

The trust has also requested donations of plastic bottles for the project, which can be dropped off at the park's visitor centre.

Last year about 20, 000 people attended the arts and culture festival themed a 'love letter' to the city.

In keeping with the theme, 2,000 paper hearts were created by schools and community groups across Peterborough in an installation called "Community Heart".
