City of Rockwall employees have become proud foster parents of a group of swallowtail caterpillars. Since June 1, City Hall has been raising butterfly caterpillars and have released over 30 butterflies since. The caterpillars are kept in a breathable mesh cage. Raising these has been fun, easy and educational. These butterflies are great to raise indoors for several reasons including plentiful food source, attractive and interesting caterpillars, and of course beautiful butterflies. The host plants of the black swallowtail include such plants as carrots, parsley, dill, fennel, Queen Anne’s Lace and rue. As a reminder there are butterfly gardens in 5 of our parks including Shores Park, The Park at Stone Creek, The Park at Emerald Bay, Harry Myers Park and Northshore Park. Check them out today!
