The caterpillars have migrated to the top of their habitat and cocooned.  See the silk threads around them?



The cocoons are now hanging inside the net habitat

Metamorphosis!  The first butterfly emerged on March 22, 2015, the second day of Spring.  I thought the caterpillars would become monarchs.  Instead, this is a Painted Lady.  Time to place an orange slice in the bottom of the habitat to feed Painted Lady.
