The Butterfly Garden: A Haven for Wild Bees

In major urban landscape such as Washington, D.C., a place like the Smithsonian Institution’s Butterfly Habitat Garden serves a valuable purpose as a rich and rewarding refuge, not only for butterflies, but also for bees. With so many flowers in bloom at the end of July, it’s easy to see that bees are very important for pollination. A bee moves from flower to flower searching for nutrient-rich nectar, which it laps up with its hairy tongue. In this process, pollen will collect on the bee’s body and be transferred from one flower to another, providing for the production of the seeds that sustain many gardens and wild-flower populations. On the hind legs of some bees, there are corbiculae, or pollen baskets.  These serve a function similar to suitcases, allowing the bees to pack lots of pollen into the baskets for the flight back home to their colony where they share their newfound resource with many others.  Solitary bees do not have pollen baskets, but species like leaf-cutter bees have very hairy abdomens, which collect a large amount of pollen.  Recently the Butterfly Habitat Garden was abuzz with a large number of bee species, including bumble-, leaf-cutter, honey, and sweat bees, all collecting resources and pollinating flowers.

Butterfly Gardens Part 2: Did you know……

Curly Parsley in the Smithsonian Butterfly Garden

As a follow-up to last week’s blog about butterfly host plants, we thought we’d add a few more varieties of host plants that are commonly grown in gardens.

In the Smithsonian Gardens’ Butterfly Habitat Garden, visitors often wonder why we’re growing parsley and tomato plants. We tell our visitors that there are a few plants popularly grown in herb and vegetable gardens which are ideal species for hungry caterpillars (which will transform into  butterflies and moths)!

Tomato Plant in the Smithsonian Butterfly Garden

Curly parsley is a popular herb that attracts Anise Swallowtails (Papilio zelicaon) and Eastern Black Swallowtails (Papilio polyxenes) in their larval stage.

Tomatoes attract several species of moths; two of them are infamous to experienced back-yard tomato gardeners. Tomato hornworm (Manduca quinquemaculata) and tobacco hornworm (Manduca sexta) are identified by the “horn” protruding from the rear of the caterpillar. Both are voracious eaters and will munch on tomato foliage and fruit. They are not welcome visitors in most vegetable gardens, but they are invited to dine in the Butterfly Habitat Garden.

If you’re willing to sacrifice some of your herbs and vegetables to sustain a few caterpillars, you will be able to witness the butterfly life cycle just as we do at Smithsonian Gardens!

Butterfly Gardens Part 1: Host Plants!

What are butterfly host plants? These plants are essentially caterpillar food. Each species of butterfly is pretty specific about the plants they’ll eat at the caterpillar stage. Butterflies will lay their eggs on plants that the newly hatched larvae will eat until they move onto the pupae stage. Hence, if you want to attract certain types of butterflies to your garden, and especially if you’re interested in seeing the egg-caterpillar-pupae-butterfly cycle, it’s important to do a little  research.

Butterfly Milkweed in the Smithsonian Butterfly Garden

The monarch lays its eggs on milkweed. An easy way to remember this, is to note the bright orange blooms of the milkweed as the monarch has similar fiery orange coloring. Butterfly milkweed (Asclepias tuberosa) is a shorter version of the common variety. As opposed to growing 3-4 feet tall, it grows only 18-24 inches.

Spice bush in the Smithsonian Butterfly Garden

Planting a spice bush is an easy way to attract spice bush swallowtails. The spice bush is a deciduous shrub which can grow as high as 6-10 feet! Hence, whether you’re looking for a small plant for the front of your herbaceous border (butterfly milkweed) or a larger plant to fill a vacant space in your yard with foliage and butterflies (spice bush), there are lots of options when it comes to choosing your butterfly plants!
