  • The Butterfly House at Humboldt Botanical Garden

    Featuring Monarch, Western Swallowtail, Red Admiral and Painted Lady

The Butterfly House at Humboldt Botanical Garden

July 1st, 2017

Butterfly House at Humboldt Botanical Garden Opens Saturday, July 1st through October 15th


Gardeners who love to butterfly garden might be interested in visiting Humboldt Botanical Garden’s new butterfly house that will open on Saturday, July 1st. This pilot project has been designed to entertain and educate gardeners and families with children. Visit the butterfly house and you will learn about butterfly habitat and the plants they love.

Local butterflies and caterpillars, such as painted ladies, red admirals, western swallowtails and monarchs will inhabit the butterfly house this summer. Currently the house has Western Tiger Swallowtail and Red Admiral butterflies and many caterpillars feeding on stinging nettle. In a few short weeks the house will be filled with active butterflies.

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.  Each child will receive a free gift while supplies last. 

The Butterfly House at Humboldt Botanical Garden is located inside the greenhouse and will be open from 12 pm until 4pm.  Admission to the Garden is $8.00 per person, children 6-17, seniors and active military is $5.00, children under 6 and members are always free.  There is a suggested donation of $3.00 for the butterfly house.

The Humboldt Botanical Garden is open Wednesday through Sunday 10 a.m. to 4 p.m.  Visit us online at  If you would like to volunteer to help with the butterfly house do give a call at 442-5139.
