Re: und es wird nicht der letzte dieses Jahr in Europa sein

Am 25. März 2019 hieß es dazu auf http://www.israelnationalnews.com/News/News.aspx/260850:

Millions of butterflies are blanketing Israel during their annual migration to Europe.

Up to a billion butterflies known as Vanessa cardui or painted lady, are passing through Israel in search of food on their way to their breeding grounds in Europe. They have been spotted in large numbers in the southern Arava region, across the Sharon Valley, and through major city centers up to the Carmel Mountain range, Israel Hayom reported citing the Association of Butterflies in Israel.

It is reportedly the largest migration of such butterflies ever seen in Israel.

A survey sample showed that many thousands per hour of the butterfly species have been seen migrating across the skies compared to just a few hundred in a similar event five years ago, according to the report, citing Noam Kirshenbaum of the association.

Butterfly sightings, which began last week, continued on Sunday."

Und auch https://www.israel21c.org/millions-of-butterflies-flutter-through-israel-on-purim/ Naama Barak vom 24. März 2019 will ich als Zitat hier festhalten: "Millions of butterflies flutter through Israel’s skies on Purim

Painted lady butterflies cover Israel's skies on their migration from the Arabian Peninsula to Europe.

Purim festivities in Israel were extra-special this year, with millions of fluttering butterflies creating the perfect backdrop to the colorful holiday celebrations taking place across the country.

The painted lady butterflies (proper name: Vanessa cardui) were making their way from the Arabian Peninsula to Cyprus and onward to the rest of Europe in the largest migration seen in Israel in recent years.

“The enormous quantities coming to us from the east are arriving from Kuwait or the Arabian Peninsula. They’re arriving in Israel, coming down for an overnight stop, fueling up and drinking nectar from the many flowers out in the fields right now, from chrysanthemums and other flowers. Tomorrow morning they’ll take off toward the shore and then northward to Cyprus and Europe,” Association of Butterfly Lovers in Israel head Dubi Binyamini said over the weekend.

“I received reports from Be’eri, from the northern Negev all the way to the Golan, a real front across all of Israel, a front of at least 200 kilometers, and then it’s simple to do the math,” he explains.

“We know how many butterflies pass each meter every minute. Multiply it by their flying time, which is at least six hours (from 8am to 2pm, even 4pm), times the front’s width. That equals at least 100 million butterflies, and in the denser areas it’s over one billion butterflies a day.”
