Fascinated pupils at Bempton Primary School witnessed the lifecycle of a butterfly, from caterpiller to chrysilis, during a school project.
Youngsters from the nursery class and reception watched as the creatures hatched into five painted lady butterflies which were then released on a pond dipping trip to Buckton.
Tracey Stainforth, class teacher at Bempton School, said: “The children absolutely loved it, watching each stage and waiting for each to hatch.
“It is really lovely for them to understand the life cycle of the caterpillars and butterflies.
“It is part of our Minibeasts topic and it gives them an understanding of nature and the cycle of life.”
The process took four weeks and the butterflies, once released, live for another month laying eggs and completing their lifecycle.
