RTÉ, or Raidió Teilifís Éireann, is an Irish public service broadcaster that produces and broadcasts programs on television, radio and online. Launched in January 1926 and headquartered in Donnybrook, Dublin, it is known as one of the world's oldest continuously operating public service broadcasters.
At the onset of the 11-minute interview, an RTÉ announcer noted that The Lives of Butterflies "showcases extraordinary diversity of world's butterflies, while exploring their life histories, behavior, conservation and other aspects of these most fascinating and beguiling insects."

Éanna Ní Lamhna is a biologist, environmental consultant, radio and television presenter, author an educator. "She is one of the best-known public figures in Ireland in the area of nature and the environment, and was listed as one of Ireland's 'Influential 100' in 2012," according to Wikipedia. She is a mainstay on RTÉ's "Mooney Goes Wild." Lamhna holds a doctorate in botany from UCD--no, not the University of California, Davis, but University College Dublin.
WSU biosketch: "David James developed a passion for entomology at the age of 8 in England by rearing caterpillars in his bedroom. He studied zoology at the University of Salford near Manchester, then migrated to Australia to work for the New South Wales Department of Agriculture on ways of controlling agricultural pests like locusts and mites. A PhD on the winter biology of monarch butterflies in Sydney followed and a career as a biocontrol scientist in horticulture blossomed." (See more here). He studies the migration of Pacific Northwest monarchs to the overwintering sites along coastal California.
What Did They Discuss?
- What exactly is a butterfly and how is it different from a moth?
- Are there more moths in the world than butterflies?
- How do butterflies hear?
- What's the largest butterfly in the world?
- What sets butterflies apart from other insects?
- What kind of digestive system do butterflies have?
- Why do some butterflies land on your arm and drink your sweat?
- Why do male butterflies feed on crocodile tears?
- Why did British scientist Miriam Rothschild call male monarchs "male chauvinist pigs?"
- How do you tag monarchs and what have we learned?
It's an excellent podcast--and you'll love listening to the lilting Irish accent of Éanna Ní Lamhna, coupled with the distinguishable English/Australian accent of David James.
And the answers to the above questions...

Question: What's better than seeing a monarch butterfly?
Answer: Seeing two monarch butterflies sharing the same blossom on a butterfly bush!
Scenario: Monarchs (Danaus plexippus) from the Pacific Northwest are fluttering through Vacaville, Calif. and stopping in our pollinator garden for some flight fuel before heading off to their overwintering sites along coastal California.
Background: I am watching for tagged butterflies from the migratory monarch project of Washington State University entomologist David James. (After all, one tagged by his citizen scientist Steven Johnson of Ashland, Ore., on Aug. 28, 2016, fluttered into our yard seven days later. James said it flew 285 miles in 7 days or about 40.7 miles per day.)
Menu: In our pollinator garden, the flight fuel includes nectar from the Mexican sunflower (Tithonia rotundifola), tropical milkweed (Asclepias curassavica), butterfly bush (Buddleia davidii), and Zinnias, a genus of plants of the tribe Heliantheae within the family Asteraceae.
Action: On Sept. 27, a male monarch touches down on our butterfly bush and begins sipping nectar. Soon, another joins him.
The two monarchs engage in what appears to be a territorial battle. It's a kaleidoscope of orange and black wings, tumbling, wobbling, recovering.
And then, wings up! The monarchs take flight.

Pollinator ecologist Anthony Vaudo, a research entomologist with the U. S. Forest Service, Rocky Mountain Research Station, Moscow, Idaho, will discuss "Pollen Nutritional Ecology of Bee-Flower Interactions" at a seminar hosted by the UC Department of Entomology and Nematology at 4:10 p.m., Monday, Oct. 16 in 122 Briggs Hall.
The seminar also will be on Zoom. The link:
https://ucdavis.zoom.us/j/95882 849672
"Pollen provides bees their primary source of protein and lipid macronutrients, essential for development, fitness, and resistance to stress," Vaudo writes in his abstract. "Yet, pollen macronutrient quality differs substantially among host-plant species. And thus, bees may be sensitive to their nutritional needs and differentially forage among host plants to obtain appropriate nutrition. In this presentation, I will highlight my research that has linked bumble bee host plant foraging preferences to pollen nutritional quality and individual and colony health. Using this as a theoretical framework, I will present recent research where I show that floral pollen nutritional quality can help explain the structure and patterns of bee-wildflower community interactions among diverse populations; and how this research can inform conservation practices. Finally, I will discuss how the quality of pollen that bees collect may differ between and remain consistent within species populations and help explain their history of floral preferences."
Vaudo, who specializes in pollinator ecology and habitat restoration, joined the U.S. Forest Service in January 2023 after serving as a postdoctoral researcher at the University of Nevada, Reno for four years.
He holds a bachelor of science degree in psychology (2003) from the University of Florida but then switched to entomology. He obtained his master of science degree in entomology from the University of Florida in 2010 and his doctorate in entomology from Pennsylvania State University in 2016. At Penn State, he was advised by Professors Christina Grozinger and John Tooke. Vaudo then served as a postdoctoral scholar at Penn State.
Vaudo was awarded a Fulbright postdoctoral scholarship in January 2018, researching "bee-flower interaction networks across different biomes in South Africa."
Seminar coordinator is Brian Johnson, associate professor, UC Davis Department of Entomology and Nematology. For Zoom technical issues, he may be reached at brnjohnson@ucdavis.edu. The list of seminars is posted here.

The event: The 13th annual UC Davis Biodiversity Museum Day, a Super Science Day.
It's an opportunity to see scientists in action.
It's day when you can visit such biological museums or collections as the Phaff Yeast Culture Collection, Bohart Museum of Entomology, Museum of Wildlife and Fish Biology, Arboretum and Public Garden, California Raptor Center, Earth and Planetary Sciences Paleontology Collections, Botanical Conservatory, Center for Plant Diversity, Nematode Collections, Marine Invertebrate Teaching Collection, and the Department of Anthropology Museum.
And it's free and open to the public.
The date has not been set, but the first few Biodiversity Museum Days took place on Presidents' Day weekend. The committee will announce the date soon.
"Each year more than 200 volunteers--students, staff and faculty--from across campus help more 4,000 visitors--including other UC Davis students, staff and faculty--learn about biodiversity through our amazing biological collections," said UC Davis Biodiversity Museum Day chair Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology.
Donations, from $5 on up, may be made at this website: UC Davis October Crowdfund campaign. It costs approximately $5000 to finance the Biodiversity Museum Day, the committee related. Donors may make contributions to honor a loved one or a favorite organism, such as a praying mantis, plant, nematode or fossil. The crowdfunding campaign ends at 11:59 p.m., Tuesday, Oct. 31.
The committee asks that you:
- Share the news with three friends/co-workers/neighbors
- Post on your social media. The UC Davis Crowdfund has links for Facebook, LinkedIn and Twitter (or X)
- Donate here
Coordinating the UC Davis October Crowdfund campaign are Yang; Brennen Dyer, collections manager for the Bohart Museum; and Melissa Cruz Hernandez, outreach and leadership program manager for the UC Davis Arboretum and Public Garden.

Often it's so camouflaged that it totally blends in with its habitat. It can rotate its head 180 degrees--and nothing, it seems, can escape its view.
Praying mantises are not considered biological pest control agents because basically they'll eat anything they can catch: from your favorite pollinators (bees and butterflies) to your favorite beneficial insects (lady beetles and assassin bugs), your favorite bird (hummingbird) to pests (stink bugs and lygus bugs) to syrphid flies, green bottle flies, and wandering caterpillars that happen to cross its path.
And they'll eat one another...catch me if you can!
Truly, they are not picky eaters like little humans who scowl at a food, push it around their plates, or "accidentally" drop it on the floor for the dog to grab.
"Over 2,000 mantid species occur in the world, mostly in tropical and subtropical regions," according to the UC Statewide Integrated Pest Program (UC IPM). "At least 9 mantid species occur in California. The Arizona or bordered mantid (Stagmomantis limbata), Bistanta mexicana, California mantid (Stagmomantis wheeleri =S. californica), Litaneutria ocularis =Litaneutria obscura, and small gray mantid (Litaneutria pacifica) are native species. Chinese mantid (Tenodera sinensis), European mantid (Mantis religiosa), Mediterranean mantid (Iris oratoria), and South African mantid (Miomantis caffra) are introduced."
"Mantids (mantises) are among the largest insects," UC IPM says. "Adults generally range from 2 to 5 inches (5–12 cm) long. Adults and nymphs (immatures) are elongate and usually brown, green, or yellowish; a single species can have all 3 color phases, such as the California mantid, Stagmomantis wheeleri =S. californica."
A mantis has two spiked forelegs that enable it to grasp and subdue its prey. It's a death grip...or a dinner grip...Ever seen a praying mantis "cradle" its prey?
This mantis, below, is a Stagmomantis limbata. Dinner was a bee. Earlier it preyed on a green bottle fly.
