The Butterfly House at Humboldt Botanical Garden

June 1st, 2018

Butterfly House at Humboldt Botanical Garden opens June 1st


We are pleased to announce that the butterfly house will reopen on June 1st with a grand opening celebration targeted for July.  This pilot project began the in the summer of 2017 and was designed to entertain and educate gardeners and families. Between June 1 and October 15, 2017 the butterfly house welcomed 3,610 visitors.

Local butterflies and caterpillars, such as painted ladies, red admirals, western swallowtails and monarchs will inhabit the butterfly house again this summer.

Typically the life of the butterfly itself is relatively brief, about two to four weeks. A butterfly’s mission after pupating is to breed and lay eggs. Much of the lifespan of a butterfly is when it is a caterpillar.  A caterpillar goes through a series of molts, shedding skin as it grows.  When it becomes large and ready to pupate, it climbs up branches and forms a chrysalis. This is the mysterious and wonderful process that produces a beautiful butterfly from a nondescript looking caterpillar.

At the Humboldt Botanical Garden’s butterfly house you will be able to witness this event.  Visitors will be able to see every stage of a butterfly life cycle from egg to butterfly.  In addition, there will be butterfly nectar plants for sale and educational information available.  

The Butterfly House at Humboldt Botanical Garden is located inside the Sun Valley Floral Farm greenhouse. Open Wednesday through Sunday from 12 p.m. until 4 p.m. $3 suggested donation.

No dogs are allowed in the Greenhouse.
