Bugs & Brews: Toxic Terrors

Guests explore the Butterfly Pavilion after dark to learn about venomous and poisonous invertebrates across exhibits such as the Wings of the Tropics conservatory. Visitors can walk through the barrier-free Spider Zone surrounded by free-roaming orb-weaving spiders, attend a surprise mystery lecture, and participate in a bug-themed costume contest. Admission includes two drinks along with a self-guided activity that awards a prize.
