About a dozen children, their parents and caregivers helped butterfly handler and tropical forest communicator Astrid Ellison release about 50 new butterflies in the enclosure inside the museum on Saturday.
From now on, members of the public will be able to assist staff every day at 10.30am.
Ms Ellison said there were usually between 50 and 200 newly-emerged butterflies to be released each day.
Often the butterflies did not fly away immediately, and staff usually spent some time gently helping them into the forest enclosure.
They recognised that morning process would be a great way to give people a chance to handle the butterflies, which were not otherwise meant to be touched.
The first release of butterflies with the help of the public had gone well, and it was easy to see how the daily release could become a popular event, she said.
"I'm really glad about the response it got. The kids were so enthused."
The newly-emerged butterflies kept the population in the forest around 1000.
Some short-lived species survive for only a few days, while others live for a month or more.
