Gardens are not only places for flowers, trees, and vegetation to grow. Insects such as ladybugs, bees, and butterflies, have an important role in our garden as well. These pollinators propagate flowers and vegetables to keep our gardens flourishing. They are so important to the survival of plants that gardeners have been known to create “homes” for these critters. Bees and wasps use insect houses to keep prey for eggs that have been deposited, while butterflies and ladybugs use them as a place to hibernate.
The Archives of American Gardens includes terrific images of insect homes. The style and size of insect houses vary just like the houses in which we live. The design of a house depends on the type of bug a gardener may want in his or her garden. For example, the size of the nesting holes drilled into the walls of an insect house influence the type of bug likely to dwell inside. The butterfly houses shown here were constructed in an elongated shape with vertical slits running up and down the sides. Butterflies must fold up their delicate delicate wings in order to fit into these narrow openings. Once inside the insect house provides the butterflies with excellent protection from wind, weather, and predators.
It is immediately apparent how the holes in this bee house vary greatly from those used by butterflies. Round holes provide bees easy entrance to the house. Unlike bee hives, bee houses are meant to attract solitary bees, such as the Mason Bee (Osmia rufa). This explains why there are multiple holes created in the house rather than one large opening like a bee hive would have.
To learn more about pollinators, attend the upcoming Pollination Party at the Smithsonian Gardens Butterfly Habitat Garden on Tuesday, June 16. The Pollinator Party will highlight the Pollinator Partnership’s mission to promote the health of pollinators–which are critical to food and ecosystems–through conservation, education, and research.
