Butterflies, Moths and Assorted Insects...

Entering 'Painted Lady" into the search field of the CR Forum leads to a number of nice butterfly shots posted by regulars here from at least three continents. Hawaii is among the locations where Painteds are found.

Ever wonder how those fliers get there?


...and...(from https://www.theatlantic.com/science/archive/2024/12/butterfly-migration-pollen-record/680911/)

"There, researchers isolated the pollen grains attached to the butterflies’ bodies and sequenced a particular stretch of the pollen DNA that offers a unique signature for each plant species, a process known as metabarcoding.

...

In 2013, for example, painted lady butterflies had been found resting on the northeast coast of South America, in French Guiana. Painted ladies don’t normally live in South America, and it was a mystery where they had come from. A decade later, Talavera’s team sampled pollen from the still-preserved butterfly bodies and found that Guiera senegalensis, a plant found only in sub-Saharan Africa, was by far the most common type of pollen attached to these butterflies.

By analyzing coastal surveys, wind patterns, pollen, and environmental conditions, they confirmed that the butterflies probably crossed the Atlantic in up to eight days’ worth of continuous flight from Africa. This finding marked the first verified instance of an insect crossing the Atlantic."

My wife and I visited Hawaii a couple of years ago. While shooting, it did cross my mind more than once: "How did these creatures get here (somebody's suitcase?!)."

I look forward to trying out new gear on some of these...
