$20 for 4 General Admission Tickets to Cambridge Butterfly Conservatory (a $52 Value)

Watch butterflies flutter by with today's WagJag: $20 for 4 general admission tickets to Cambridge Butterfly Conservatory (a value of up to $52).

The Conservatory invites you to enter a lush tropical garden and walk amongst thousands of fluttering butterflies. At least 2,000 free-flying tropical butterflies are on exhibit at any given time in the tropical Conservatory. The butterflies originate from either Costa Rica or the Philippines and arrive weekly as pupae from butterfly farmers.

Butterfly farming is a sustainable form of agriculture and ensures that natural populations of wild butterflies and moths are not depleted. At the Conservatory's Emergence Window, visitors can watch as butterflies emerge from their chrysalides, dry their wings and prepare for their very first flight into the Conservatory. Some butterfly species are reared on site so that visitors can observe all four stages of metamorphosis: egg, caterpillar, pupa and butterfly. The population of butterflies consists of approximately 40 different species. The butterflies aren't the only species at the Conservatory; there are also birds, plants and insects to observe.
