Red Admirals can be spotted throughout the DMV, but you better hurry if you want to catch a glimpse! At first frost these little creatures will start their journey south. Bug Of The Week has what you need to know to start your search:

On Saturday April 24 the Entomology Department joined AGNR and UME to participate in UMD Day at the Maryland State Fair. Our Insect Zoo guru, Todd Waters, organized a group of wonderful volunteers to run the tables and Dr. Michael Raupp carried a forward detachment of chitinous friends for an early morning interview on Fox45 Baltimore to advertise the event. We were provided tables in the 4-H and Home Arts Building and arrived before noon with a car full of terraria and arthropods. Before we could even set the first enclosure on the table, we were surrounded by a swarm of curious onlookers squirming in shock and fluttering with excitement. They were but moths, and our exhibit the finest lamp. Dr. Leslie Pick, covered in stick bugs, and Dr. Raupp, with a large tarantula in his hands, flourishingly convinced terrified spectators to hold Malaysian Giant Leaf Bugs, and our illustrious Chilean Rose Hair Tarantula “Rosie,” all of them becoming instant fans.
Professor Emeritus, Don Messersmith, who retired in 1989, celebrated his 90th birthday last December. After he retired from the University of Maryland in 1989, he continued to teach adult courses in Orthnithology in the DMV area and still continues that work today. He teaches part-time to senior citizens enrolled in the Osher Program at Johns Hopkins University in Rockville. The course he is currently developing for the upcoming Hopkins’ program is titled "Culture and Wildlife." The course will focus on how cultures around the world incorporate wildlife into their ceremonies, traditions, art, dances, costumes, etc.

This summer, Lisa Kuder (PhD Student, vanEngelsdorp lab) wrapped up her research project with The Maryland Department of Transportation State Highway Administration (MDOT SHA) titled, “Evaluating Integrated Roadside Vegetation Management (IRVM) Techniques to Improve Pollinator Habitat.” This three-year field study had two main goals: to determine which vegetation management tactics best maximize quality floral resources for pollinators in the Northeast, and to assess how those different regimes affect regional bee populations. The findings show that managing roadsides via selective herbicide use (SH) and annual fall mow (fall mow) can significantly increase floral diversity and bee abundance compared to a traditional frequent mowing (turf) regime. While differences between treatments – SH and fall mow – were detected, they were not significant. Bee diversity, which accounts for both abundance and the evenness of species in a given area, was mainly determined by site/surrounding landscape not treatment and was the sole significant factor. Given that floral abundance and diversity, as well as bee abundance, were increased under SH and fall mow compared to turf plots, both Integrated Roadside Vegetation Management (IRVM) practices have shown great potential in supporting pollinators.

Congratulations to the vanEngelsdorp Lab for their work on the 13th Annual Honey Bee Loss Survey. The 13th Annual BIP Honey Bee Colony Loss Survey was released in June. The survey showed that U.S. beekeepers lost almost 40% of their bee colonies last winter, the largest loss recorded in 13 years. Researchers are using this data to establish best management practices that will help beekeepers improve the health of bees.
Thanks to the Colleges’ communication teams the survey gained widespread media coverage. Read the CMNS press release here>>
