They're among the most recognizable of insects. And excellent predators of aphids and other soft-bodied insects!
"There are about 5,000 different species of ladybugs in the world," according to National Geographic. "These much loved critters are also known as lady beetles or ladybird beetles. They come in many different colors and patterns, but the most familiar in North America is the seven-spotted ladybug, with its shiny, red-and-black body. In many cultures, ladybugs are considered good luck."
Morgan Myrhe, a UC Davis graduating senior in entomology who won the Citation for Outstanding Performance in Entomology at her commencement last week, says that in elementary school, she frequently brought "ladybugs into the classroom" in her pockets and "established a worm club with her friends."
Morgan, born and raised in San Diego, said her educational journey followed a nontraditional path. WIth very limited high school experience due to a severe illness, she began attending Palomar Community College at 16 years old. While in community college, she worked at the San Diego Zoo Safari Park and had her two children, Galileo and Esmerelda.
Morgan currently works as a math and science tutor at Pioneer High School and as an undergraduate research assistant in the Ian Grettenberger lab at UC Davis. She plans to obtain her science teaching credentials and master's degree in education and to "continue exploring my love for entomology by introducing my future students to the subject."
Katherine "Katie" Hostetler, named the Outstanding Senior in Entomology, remembers "gardening with my mom and picking up snails, isopods, and other creatures while playing in the dirt. I also volunteered at the local botanical garden in high school, which confirmed my interest as I got to hang out with insects while gardening!"
Professor Sharon Lawler, an aquatic entomologist in the UC Davis Department of Entomology and Nematology who retired in January, nominated Katie for the award. "I worked with Katie through the Research Scholars Program in Insect Biology (RSPIB)," Lawler said. "She participated in graduate student Kyle Phillip's project on how wetland plant decomposition supports aquatic food webs in the Sacramento-San Joaquin Delta (Suisun Marsh). Katie rapidly became an essential member of the research team, which included John Durand as a principal investigator and Kyle's co-advisor."
"Katie learned numerous techniques in aquatic ecology," Lawler said. "She ultimately designed and led her own laboratory experiment on how amphipods contribute to nutrient recycling in wetlands through shredding and consuming different kinds of detritus. She is working on a draft manuscript for a peer-reviewed journal stemming from her work."
Katie plans to remain in Davis and "continue working at the Center for Watershed Sciences in invertebrate research!"
Congratulations to Katie and Morgan!

They really weren't red ants, but children wearing ant headgear, created during the family arts-and-crafts activity at the Bohart Museum of Entomology's open house on ants. The Phil Ward lab, UC Davis Department of Entomology and Nematology, organized and presented the open house.
The ant headgear was the brainchild of Tabatha Yang, education and outreach coordinator, and student intern Jakob Jess of MET Sacramento High School. He completed his two-year internship at the Bohart Museum this week, and starting this fall, will begin his studies at UC Berkeley.
"This was an art project inspired by leafcutter ants," Yang said, "and was meant to be both whimsical and colorful, thus the bright red. We had a template for folks to use, but they could also create their own from looking at the ant illustrations."
Myrmecologist Eli Sarnat, who received his doctorate at UC Davis, studying with Professor Ward, brought his sons, Benjamin, 7 and Evan, 3 to the event. They delighted in creating the ant headgear and checking out the ant displays.
UC Davis senior entomology major Morgan Myhre helped her children, Galileo, 5, and Esmeralda, 2, with their creations.
First-year entomology major Kat Taylor staffed the arts-and-crafts table, assisting the youngsters with their ideas. She also stapled the finished projects.
"The questions were mostly about the habits and behavior of ants, how many species are there, etc.," Ward related. "And how can I obtain live colonies for my kid? I received almost no queries about 'how do I get rid of them in my kitchen?' and that was refreshing."
"We had live colonies of a centipede-hunting ant (Stigmatomma oregonense) and a generalist omnivore (Aphaenogaster occidentalis)," Ward said. "The displays also included collections of common California ants; the world's smallest ant (Carebara) and the world's largest ant (Myrmecia)."
Oberski, who received her bachelor's degree in biology and a bachelor's degree in German studies (summa cum laude) in 2016 from Macalester College, Saint Paul, Minn., finished her dissertation earlier this month. She will present her exit seminar on "Phylogenetics and Biography of Pyramid Ants" at 4:10 p.m., Wednesday, June 7 in 122 Briggs Hall. It also will be on Zoom.
Oberski fielded such questions as "What do ants eat?" and "Are ants specialized or generalized in their feeding habits?" The answer can vary a lot, Oberski told them. "Some ants are generalists that eat any food they come across, but others are extremely specific, like ants that are fungus farmers or specialized predators of springtails, spider eggs, or centipedes."
Professor Ward and ants are showcased in a Bohart Museum of Entomology video on YouTube, https://youtu.be/d8eRNsD8dxo. Ants, he related, originated about 120 million years ago (early Cretaceous), evolving from "wasp-like creatures."
Next Open House on June 3. The next open house at the Bohart Museum is themed "Insects and Forensics," and will feature forensic entomologist Robert "Bob" Kimsey of the UC Davis Department of Entomology and Nematology. Free and family friendly, the open house will take place from 1 to 4 p.m., Saturday, June 3 in Room 1124 of the Academic Surge Building, 455 Crocker Lane. The arts-and-crafts activity will be "maggot-inspired art," Yang announced.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens. It also maintains a live "petting zoo," complete with Madagascar hissing cockroaches, stick insects, and tarantulas, among others; and an insect-themed gift shop, stocked with books, posters, jewelry, pens, T-shirts, hoodies, and collecting equipment.
