Behind the Scenes of Olbrich's Blooming Butterflies
Preparing for Olbrich's Blooming Butterflies takes lots of planning from many staff members, and the contributions of many volunteers. Butterflies arrive by US mail as chrysalises, and are put in hatcheries where they emerge as butterflies and fly freely in the Bolz Conservatory.
Olbrich's Blooming Butterflies is open July 15 through August 9, from 10 a.m. to 4 p.m. daily.
Butterflies arrive

A shipment of butterfly chrysalises arrives by US Mail. Shipments arrive twice each week.
Sorting Chrysalises

Volunteers sort and inventory chrysalises by type of butterfly.

pinning chrysalises

Volunteers glue chrysalises onto string. The string is attached to wooden dowels, which are put in the hatcheries.

Chrysalises

Chrysalises hang in the hatchery. A butterfly has already emerged from the chrysalis on the left. The butterfly is almost ready to emerge from the chrysalis in the middle. The chrysalis on the right will probably hatch in a few days. Monarch chrysalises turn from light green to translucent as the butterflies get closer to emerging.
