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.

They are a beautiful sight.
Hopefully, tagged migratory monarchs from the research project of entomologist David James of Washington State University, will pass through--as they do every year from the Pacific Northwest--on their way to their coastal California overwintering sites. They are tagged on a discal cell.
Meanwhile, scientists in the Northeast are tagging monarchs (heading for Mexico) in a different way. They're attaching "small, lightweight tracking devices to nearly 50 strong and healthy butterflies," according to the New Hampshire Public Radio, in a piece published Sept. 12. "Towers can then ping their location when the small creatures are nearby."
The article related that "Scientists across the country are studying their migration patterns through a project funded by the federal government. This is the second full year that the New Hampshire Audubon Center is participating in a monarch tracking program."
The article by Olivia Richardson quotes Diane De Luca who works at the center: “The thought behind tagging monarchs here in the Northeast is to get a better sense of what they actually do when they're first starting their migration."
The tracking devices are lightweight, but the scientists seek out "strong, younger butterflies" without tattered wings. (See more on the website)
One tracked butterfly flew 60 miles in one day.
"De Luca said last year a butterfly they tagged traveled to Massachusetts and stopped at Lynnfield Marsh, one of the state's largest freshwater marshes," Richardson wrote. "De Luca said purple loosestrife, a type of flower considered an invasive species, is abundant at the marsh and it's attractive to monarch butterflies, who feed off of it."
Aren't monarchs fascinating?
Ping! There goes another butterfly!

If you live in California, tagged monarchs from the migratory research project of entomologist David James of Washington State University may be heading your way.
One tagged monarch, a male, fluttered into our Vacaville pollinator garden on Sept. 5, 2016. Citizen scientist Steven Johnson of Ashland, Ore., tagged and released it on Aug. 28. It nectared on Mexican sunflowers (Tithonia rotundifola) and a butterfly bush (Buddleia davidii) before heading to an overwintering site in coastal California.
The tag read “Monarch@wsu.edu A6093.”
James later told us: "So, assuming it didn't travel much on the day you saw it, it flew 285 miles in 7 days or about 40.7 miles per day. Pretty amazing."
If you see a tagged monarch ("quite a few are being tagged in southern Oregon," James says), try to take an image. Then detail the information (where spotted and when) and send it to the WSU entomologist at monarch@wsu.edu. Read more on his Facebook page, Monarch Butterfies in the Pacific Northwest.
Meanwhile, we've been seeing monarchs daily in our garden since late August. We spotted one monarch laying eggs on our tropical milkweed, Asclepias curassavica, on Aug. 10. (That was her choice of milkweed: she ignored the narrow-leafed milkweed, A. fascicularis; the showy milkweed, A. speciosa; and the butterfly weed, A. tuberosa.)
On Sept. 5, two monarchs, a male and a female, eclosed, while a male monarch patrolled overhead. The newcomers dried their wings and fluttered off. Both managed to escape several predators: Western scrub jays, praying mantises, and assorted crab spiders.
Welcome to the world!

The seventh annual International Monarch Monitoring Blitz will take place Friday, July 28 through Sunday, Aug. 6.
That's when community scientists from across North America--United States, Canada and Mexico--will "come together with the shared goal of helping to protect and conserve the beloved and emblematic monarch butterfly," the organizers said. "Data collected by volunteers each year support trinational efforts to better understand the monarch butterfly's breeding productivity, range, and timing in North America."
So, during this 10-day period, we will look for monarchs, as well as eggs, caterpillars and chrysalids, and load the data via the Trinational Monarch Knowledge Network, "a central repository that, in combining data from various sources, assists researchers in performing large-scale temporal and spatial analyses. The data collected by volunteers help researchers answer key questions about monarch butterfly and milkweed distribution, timing of reproduction, and the use of natural resources. In turn, this information helps conservationists identify and prioritize actions to conserve the species."
Ready to participate? All you have to do is share your data with one of the community science programs below:
- Journey North (journeynorth.org)
- Mission Monarch (mission-monarch.org)
- Monarch Larva Monitoring Project (mlmp.org)
- Naturalista (naturalista.mx)
- Correo Real Program/PROFAUNA A.C. (https://www.correoreal.mx/)
- Western Monarch Milkweed Mapper (monarchmilkweedmapper.org)
The Blitz is organized by the Trinational Monarch Conservation Science Partnership, a collaboration of organizations, including the Commission for Environmental Cooperation, Insectarium/Montréal Space for Life, Environment and Climate Change Canada (ECCC), the Monarch Joint Venture, Journey North, the US Fish and Wildlife Service, the Xerces Society for Invertebrate Conservation, PROFAUNA AC/Correo Real Program, and Mexico's Comisión Nacional de Áreas Naturales Protegidas (Conanp).
Last year's effort resulted in 5988 observations, 2698 participants from 75 states and provinces, 19,222 monarchs observed, and 68,847 milkweeds examined.
Also, you can sign up for the Commission for Environmental Cooperation's newsletter here.
We remember that in 2016, our Vacaville pollinator garden thrived with 300 monarch eggs and caterpillars. The most exciting event? On Monday, Sept. 5, 2016 a citizen-tagged monarch fluttered into our yard from Ashland, Ore. This was part of a migratory monarch project headed by entomologist David James of Washington State University, my alma mater. Community scientist Steven Johnson of Ashland tagged it on Aug. 28, numbering it A6093.
"So, assuming it didn't travel much on the day you saw it, it flew 285 miles in 7 days or about 40.7 miles per day," James told us. "Pretty amazing. So, I doubt he broke his journey for much more than the five hours you watched him--he could be 100 miles further south by now." (See Bug Squad blog)
Now, to keep our eyes open for Danaus plexippus--the adults, eggs, caterpillars and chrysalids--during the July 28-Aug. 6 blitz.
Zero sightings in our yard so far this year!
