What is rarity in bees and why do we care? Dr. Michael Roswell addressed this question during the weekly Entomology seminar series. Dr. Roswell recently joined the Espíndola Lab (EspíndoLab) at the University of Maryland after completing his Ph.D. in Ecology and Evolution at Rutgers University earlier this year.
The Song of the Lacewings: A look into the unique mating call of the green lacewing and why their larvae fake their death.
Many people are fascinated about the diversity in nature, some are attracted by cichlids with various colors, others were allured by butterflies with different patterns. Katherine Taylor, a new Post-doc in the Fritz lab, was interested in the diversity of the lacewing mating songs.
For nearly the last two decades, STEM educators, particularly those in biology, have been moving toward a more active learning model for undergraduate courses. Dr. Marcia Shofner has been at the forefront of that effort at University of Maryland. Dr. Shofner is a Senior Lecturer in the Entomology Department, teaching several sections per year of Ecology and Evolution. Not only is this course often an early undergraduate’s first introduction to college biology, but it is often a Graduate Teaching Assistant’s first foray into teaching as well. At this week’s colloquium, Dr. Shofner shared a “peer through the lens” into designing and implementing an active learning course with the Entomology community.
In the spring of 2004, millions of 17-year cicadas emerged from the ground. They crawled over trees, houses, and cars. They molted leaving exoskeleton shells on every surface. Birds feasted. Squirrels gorged themselves. Newly planted trees suffered. Children tiptoed though carcasses on their way to school. Parents scraped goo off their car’s wheels. The air vibrated with the cacophonous sound of cicadas. Then they were gone. But next year they are coming back. Whether you anticipate it with dread or excitement, they are coming again.
In his colloquium presentation to the UMD Entomology Department, Dr. Mike Raupp, an emeritus entomology professor at the University of Maryland, brought us up to speed on the coming emergence of periodical cicadas. The last time Brood X, the 17-year cicadas local to this area, emerged from the ground, entomologists were in heaven. Dr. Raupp gave numerous talks around the country even ending up on Jay Leno’s late-night show to teach about the fascinating insect. He explained how 17-year cicadas are a great opportunity to get people interested in bugs. Next year, they may be even more numerous due to recent habitat restorations and improved tree cover.
Congratulations to Entomology’s Alys Jarvela and Leslie Pick whose paper was just published in Communications Biology. Their research showed that mosquitos lost a gene that is essential for survival in other insects without ill effects. They also found that a related gene stepped in and took over the lost gene’s role. This discovery represents the first time that scientists identified a gene that naturally evolved to perform the same critical function as a related gene long after the two genes diverged down different evolutionary paths.

Seven months into the global COVID-19 pandemic, Dr. Leslie Pick, department head of entomology, kicked off the department’s fall colloquium series in a way that’s become familiar; she muted the audience, thanked everyone for coming, and shared her screen.
Past colloquium speakers have talked about the latest research in entomology, but Dr. Pick talked about topics even more important: COVID-19 and racism. Addressing COVID, she took us back to March by reminding us that over a one-week period the department transitioned from normal research to working from home with severe research restrictions. When you’re working with live animals and cultures, however, this doesn’t mean hitting a pause button. The whole department mobilized to care for colonies of insects and live cultures on campus or bring them home. Bringing home wolf spiders, lady beetles, and mantises was a new adventure for many and even attracted the attention of Nature and NPR.
In a paper published in Genetics today (https://www.genetics.org/content/215/4/1027) Entomology graduate student Katie Reding (Pick lab) used CRISPR/Cas9 to make a genomic deletion of the white gene in the milkweed bug Oncopeltus fasciatus. The white gene was one of the first genes identified in Drosophila, over 100 years ago, where it is necessary for the red eye color of flies. Interesting, in Oncopeltus, white is necessary for pigmentation throughout the body but it is also necessary for organismal survival, as animals homozygous for the white mutations do not survive to adulthood. This is the first demonstration that CRISPR is effective in Oncopeltus. Methods Katie developed will be useful for researchers to test the function of other genes in this and related species.
Entomology's Mike Raupp weighs in on enormous wasps about to emerge en masse throughout the eastern half of the U.S. to hunt cicadas—and to worry people. They are black with caution-yellow markings and the size of a USB stick.

TikToks About Strawberries With Bugs In Them Are Going Viral, But Experts Say It’s Rare, reports Bustle. "When we eat any food, animal or vegetable, we are actually consuming many different types of organisms, bacteria, fungi, and yes, sometimes insects or parts of insects," Professor Emeritus. Mike Raupp, tells Bustle.
There has been much confusion about whether murder hornets are in Maryland. No, the murder hornet is not in the DMV yet but there are hornets that look similar, says UMD Professor Emeritus, Mike Raupp. He shows viewers how to ID common MD look a-likes.
Congratulations to Environmental Science and Policy major, Maggie Tan (Palmer Lab), who successfully defended her entomology honors thesis last week. Her thesis entitled, “Changes in Hydrology and Water Quality Resulting from a Regenerative Streamwater Conveyance System in Campus Creek", received honors. Under the supervision of Michael Williams, her honors thesis investigated how Campus Creek’s regenerative stream conveyance restoration project influences the water quality of the Chesapeake Bay. Maggie used hydrological and water chemistry data to document changes that occurred in Campus Creek, on the north side of campus, when step pools were placed in the stream in 2019. Their data provides a preliminary picture that RSC may reduce runoff as well as nutrient and sediment concentrations.
It has been wonderful having Maggie in the Entomology Honors Program. She graduated from UMD Environmental Science and Policy program this Spring with a concentration in Geosciences and Restoration and minoring in Geochemistry. Maggie has plans to start graduate school this fall in Arizona.
Despite challenges presented, Entomology kept teaching, kept learning and kept working during the spring 2020 semester. Check out research & teaching during COVID, promotions, publications, awards, defenses, workshops and much more.
Does where you breed change how you live? Differences in host seeking and chemosensory gene expression between above- and below-ground mosquito populations
written by: Mike Nan, PhD student, St. Leger lab and Dylan Kutz, MS student, Lamp lab
Anna Noreuil, an M.S. student in the Fritz Lab in the Department of Entomology at the University of Maryland, has been studying host-seeking behavior and differential chemosensory gene expression in above- and below-ground Culex pipiens for her master’s research. Cx. pipiens (Diptera: Culicidae) is a mosquito found in the northern regions of the U.S. and is also found in urban and suburban temperate areas around the world. Cx. pipiens is the primary vector of West Nile virus (WNV), a mosquito-borne disease that affects the nervous system, in the Northeastern US. Oddly, although there is only one species known as Cx. pipiens, two “bioforms” of the species exist which are morphologically indistinguishable but genetically, physiologically, and behaviorally different: “Cx. pipiens form pipiens” and “Cx. pipiens form molestus.” Cx. pipiens form pipiens differs from Cx. pipiens form molestus in three distinct ways: (1) it breeds in above-ground habitats, (2) it requires blood meals for egg production, and (3) it prefers avian hosts over humans (Figure 1). However, these two “bioforms” readily hybridize or crossbreed and as such they are both classified as the same species (Figure 2).
Dr. Bill Lamp is seeking an undergraduate student, sophomore or junior, to join his lab as a part-time intern, 10-15 hours/week, to focus on molecular approaches applied to the study of plantinsect interactions of an invasive insect, the spotted lanternfly. The position requires a current University of Maryland student who has experience with molecular biology and basic molecular techniques, or has a strong desire to learn them. The student will use molecular techniques to aid in the identification of host plants of the spotted lanternfly using DNA barcoding of their gut contents. Entomological experience is not required, but an interest in or willingness to learn about insects is useful.
