There are around 80 butterfly species native to Orange County, where once there were over 100. The greatest threat to butterflies is habitat loss due to residential and commercial development. Climate change, widespread pesticide use, and invasive species are also threatening many species of butterflies, because of impacts on the native host plants they depend on. You can help butterflies by planting native plants in your yard! Each butterfly species needs specific host plants to eat as caterpillars. They also require plants that provide nectar as adults. You can visit the Environmental Nature Center at 1601 E. 16th Street in Newport Beach on weekends from 10AM to 3PM. On warm sunny days you’re likely to see butterflies along with a number of birds and other native wildlife.
The Butterfly House is open intermittently. Be sure to call before coming. In the Spring and Summer there are PLENTY in the Center (along the trails) on warm, sunny days, so please visit between 10AM and 3PM on Saturday or Sunday to see them flying wild and free!
The House is frequently in use for our scheduled programs. Please call before coming if you plan to bring more than a few people with you, as there is limited space in the House. Note that if the weather is cold or overcast, the butterflies may be significantly less active. You may want to check our weather before coming.

It can confuse scientific studies of butterfly migrations.

Monarchs to the west of the Rocky Mountains overwinter along the Pacific coastline of California and move inland in the spring to reproduce.
