Summertime Nature in New Jersey. Sourland Mountain Preserve.

Pair of Yellow Swallowtail Butterflies Near the Pond at Sourland Mountain Preserve in New Jersey. Image taken with a Nikon D4 camera and 80-400 mm VRII lens (ISO 180, 400 mm, f/5.6, 1/400 sec).

In previous years I have seen these butterflies congregate near this pond in areas with wet mud. Another time, they were on a dead ground-hog. I wonder if they are looking for a source of salt?

I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer updating images in My Image of the Day Photoblog, and My eBird (with images of nearly 450 bird species). hope post COVID-19 to be a world traveler again. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
