Monarch Butterflies Could Number 200 Million This Year

04.03.2011
Despite recent cold snaps that brought record-setting low temperatures over much of Texas, the outlook for the annual Monarch butterfly invasion to the state looks promising “and better than expected,” says a Texas A&M University researcher.

Craig Wilson, a senior research associate in the Center for Mathematics and Science Education and a long-time butterfly enthusiast, says the numbers of Monarchs entering the state over the next few weeks should be very strong.

“The numbers are better than expected and the Monarch appears to have recovered to 2008-09 levels in their over-wintering sites in Mexico,” Wilson explains.

“The area of trees that are spread between about 12 sites where they hang, or what is termed festoon, for warmth has increased from about five acres last year to 10 acres this winter. That is very good news.

“Recent studies show their numbers this year could be about 200 million overall, which would be quite amazing since they were down almost 50 percent this time a year ago.”

Most of the Monarch reserves are in the Mexican state of Michoacan. It’s an area where Monarchs spend the winter and mate before heading north, and these breeding areas can contain 50 million butterflies within just a few acres, Wilson points out.

During their migration, Monarchs get about 70 percent of their food supply while flying their routes through Texas, and succeeding generations eventually fly 1,500 miles north to Canada.

While Monarchs are the most commonly seen butterfly in the region, Wilson says residents can also see Swallowtails, Skippers, Blues, Metal Marks, Whites and Sulphurs.

“There are about 450 different butterflies and over 550 types of moths that visit Texas, so there really are a lot of butterflies out there,” he adds.

He says the full migration patterns should begin soon, and Southwest residents should be able to see Monarchs and others in the next few weeks, adding that “several have already been spotted in the Friendswood area.”

Wilson recommends two websites, www.monarchwatch.org, and www.thebutterflysite.com, where anyone interested can learn more about Monarchs and other butterflies.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
