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.

As a Structural Entomologist, I primarily deal with pests found in any typical urban environment, including cockroaches, ants, flies and rodents; however, working in a museum, I also encounter a completely different classification of pests that provide their own unique challenges.
Wood infesting insects, stored product pests and fabric and paper pests can destroy museum objects in a relatively short amount of time. A carpet beetle or clothes moth that might put a few holes in a $40 sweater could completely decimate an artifact like a wool cap from the Civil War. It’s important to identify pests correctly and to know the early signs of an infestation before an object is irreversibly damaged.
Museum pests are not a topic that is typically covered at pest management conferences or in industry journals or websites. This is why I was so excited to have the opportunity to attend “Museum Pests 2014: Integrated Pest Management for Museums, Libraries, Archives and Historic Sites” in Colonial Williamsburg, thanks to the Smithsonian Gardens travel grant program earlier this year.
There was an overwhelming number of presentations, workshops and tours to choose from during the two day conference including topics such as pest identification, treatment options, record keeping, Integrated Pest Management policy, and health and safety. Workshops that I attended included tours of the Colonial Williamsburg Historic Area and the Collection and Preservation Facilities.
It was reassuring to meet with museum professionals from all over the world and to learn that all of us experience the same basic challenges regardless of whether we work in large complexes or small, historic homes. The information that I gathered in two short days has been indispensable in my encounters with museum pests.

At the end of April, after ten months of planning, coordinating, and troubleshooting, the Smithsonian Gardens Orchid Collection (SGOC) went live. No, we didn’t kill off all of the plants over the winter and revive them for this announcement . . . I mean live as in on-air, online, and freely accessible! SGOC is now available for the world to explore on the Smithsonian Collections Search Center and is the only living collection to join the multitudes of objects, specimens, and archival records that are contained within the site. Below is a snapshot of what an individual catalog record looks like:
Records are updated twice a month and contain basic information about each accession, such as scientific name, flower color, range (if a species), and taxonomy. One of the best parts of having the collection online is being able to peruse the beautiful images taken by our talented volunteers Gene Cross, Bryan Ramsay, and James Osen. So far, about a third of the records have images associated with them. We only photograph the orchids when they are in bloom, but many of our orchids (especially the species) are either too small to bloom, or haven’t yet bloomed during their time at the greenhouses.
SGOC’s presence on the Collections Search Center is serving as motivation to improve Smithsonian Gardens’ collection records in BG-BASE and correct plant identification errors. Our hope is that these records can be a valuable resource for educators, students, researchers, and curious individuals, and a source of orchid inspiration year-round.
