Youngsters at Rougham Acorns and Woodlands Pre-school Holiday Club learnt about bats when Libby Ranzetta, of Bury St Edmunds Bat Rescue, visited with two bats.
Aged between three and 11, the children discovered how bats get around in the dark, what they eat and where they live.
Freddie the pipistrelle, which is Suffolk’s smallest bat, and Dolorosa the noctule, one of the largest, were on hand to demonstrate their echolocation calls.
The children were able to see for themselves how bat wings resemble the human hand and how many toes they have - five on each foot.
Vanessa Cameron-Laker, pre-school manager, said: “The children were so excited to see the bats, they didn’t stop talking about them for the rest of the day. They have been learning about nature and the environment, so this fitted in very well with our theme for spring.”
Libby Ranzetta, director of BSE Bat Rescue, added: “The children were really interested and asked some excellent questions. It was a great opportunity to talk to young people about bats and dispel a few myths.
“As a protected species, bats need people on their side and it was lovely to see everybody’s enthusiasm for these amazing creatures.”
