The main aviary replicates a natural rainforest environment, with special attention to the needs of our most nervous butterfly, the Ulysses. The landscaping within the aviary is often remarked upon, especially by keen gardeners. There is both a rainforest under-storey and canopy, as well as a running stream, complete with waterfalls, creating a natural looking and feeling rainforest setting. Butterflies are extremely fragile creatures, and the right conditions must be in place to ensure conditions are conducive to butterflies completing their complex courtship rituals. Free guided tours through the flight aviary and laboratory are available during the day.
