Join the London Wildlife Trust in Grosvenor Square on Saturday 20 May to learn about the brilliant butterflies in our city.

From 12pm to 4pm, families can take part in butterfly-themed crafts and activities, including butterfly print making, making butterfly feeders, crafting butterfly magnets, and story time with The Hungry Caterpillar.

Drop in any time to create a butterfly feeder to attract butterflies to your garden, patio or window ledge.

There will also be a butterfly craft workshop for adults and children over 12 where you can create your own butterfly print. There are two sessions suitable for adults, from 12pm to 12.45pm and 2.15pm to 3pm.

There will also be a butterfly craft workshop for families with children. Listen to the story of The Hungry Caterpillar then decorate your own caterpillar and butterfly. There are two sessions for families with children age under 12: 1pm to 1.45pm and 3.15pm to 4pm.
