Library Adventures with Monarch Butterflies

For the third year in a row, Crestwood Library has participated in the Rockefeller Preserve Monarch Butterfly Project. What an adventure it was to hunt for Monarch eggs at Rockwood Hall, collect them to hold at the library, watch them grow into caterpillars and transform into butterflies!
We had a great time learning about their life cycle and lots of fun releasing the butterflies. We are glad to play a part in the preservation of these beautiful butterflies and to support them as they head out for their migration journey to Mexico. We released the last two of fifteen butterflies this afternoon.
A big thank you to Friends of Crestwood Library, Mayor Mike Spano, Commissioner Steve Sansone
