OCCOQUAN BAY NATIONAL WILDLIFE RESERVE - FRIDAY - 10-22-21 - PART 3

 We are walking along looking at the river.  We can see the State of Maryland in the distance.  It is very peaceful, the river on one side of the trail and trees on the other, with their colors turning into Autumn gold...and one of the many reasons to go for a walk at this time of the year and take it all in. We pass small streams, run-offs here and there... and notice that there are fish, what kind I don't know.A favorite quote next by A. A. Milne...my philosophy basically, especially when on these walks."Rivers know this: there is no hurry.  We shall get there someday.""I don't need very much now," said the boy, "just a quiet place to sit and rest.  I am very tired."  "Well," said the tree, straightening herself up as much as she could, "well, an old stump is good for sitting and resting.  Come, Boy, sit down.  Sit down and rest."  And the boy did.  And the tree was happy.

"I imagined your stick, washing in the waves for hundreds of years, turning to driftwood, smooth and hard like stone.  I imagined a little girl finding it on a beach so many years later.  Saving it on her shelf, where she put the things that made her feel like the world was magical."

~Ava Dellaira~

An old duck blind returning to the water, to become driftwood perhaps?

We found the loop back to our car.  Neither of us felt like going the whole way round, and took the shorter trail down the middle.

Gregg is in the distance taking his own photos, and I am lollygagging again...and my dear Mum used to complain when Dad was 15-20 paces ahead.  For some reason this photo made me think of Mum with Dad striding ahead.  We used to tease him that he only had three speeds, fast, very fast and faster still, but she was a lollygagger and yes I am smiling. This time I was taking photos of leaves on the path....

and I just remembered who I got my lollygagging from.  Thanks Mum, you taught me to slow down and smell the roses.  Or in this case, take a look at the leaves on the ground. As for Dad, one of his favorite hobbies was taking photos. He also passed on his love for animals and flowers, to respect all things in nature.  Thanks Dad!

One last bench before reaching the car.  It was in front of this area.  All water birds seem to have flown south for now.

I looked nearby and found this interesting plant next to the lily pads.  A new one for me.  It is Floating primrose-willow (botanical name Ludwigia peploides).  Its other names are Creeping water primrose and Water Primrose, and is an herbaceous perennial wetland plant.

Earlier at the side of the path I came across this pretty yellow flower, also a type of Primrose but this one an Evening-primrose (botanical name Oenothera biennis).  Also known as German rampion, Fever plant and Common evening primrose.  It is another herbaceous perennial, recognized by its flowers that open in the evenings and close again at sunrise.  It wasn’t exactly evening but this part of the path was very shady.  

Next we have Lateflowering thoroughwort (botanical name Eupatorium serotinum).  Also known as Late boneset and Fall boneset.  Native Americans and early settlers used the plant for medicinal purposes, and the name thoroughwort is given for this reason.  It has the intrinsic value of being native to the land.  Also, this flower has been part of an ecosystem special to North America for millennia.

I couldn't find the proper name for these grasses, other than it was a fountain grass.  I liked the look of it so took a photo...

and the same for this one, a dried up plant with an interesting oval shape.  When I took a photo of it in my plant app just now, it said it also was an Evening primrose.

And that's about it for our trip to Occoquan Bay National Wildlife Refuge.  I hope you have enjoyed it.

Thank you for stopping by, have a wonderful weekend, and don't forget to do a bit of lollygagging.  You deserve it!

OCCOQUAN BAY NATIONAL WILDLIFE RESERVE - FRIDAY - 10-22-21 - PART 2

We reached the water and it was wonderful!  Across the river is Maryland.  We are on the Virginia side. More on this part of our walk in the next post.

In my previous one I promised you butterflies.  We found a pair on the Frost Aster (botanical name Symphyotrichum pilosum), but I won't go into any more detail on the flower today, as I am going to concentrate on butterflies (and later in my post the snails, which aren't quite as pretty but totally fascinating all the same.

 Gregg took photos of the pair.  

I couldn't tear myself away and took several single shots.  It has been a rare sighting for me this past summer.  I was very happy when I spotted them.Named for its conspicuous target-shaped eyespots, the common buckeye, Junonia coenia Hübner, is one of the most distinctive and readily-identifiable North American butterflies. 

The common buckeye is a resident across the southern United States and much of Mexico, and regularly expands its range northward each year to temporarily colonize much of the U.S., occasionally reaching southern Canada. Starting in late summer and continuing through fall, huge numbers of adults migrate southward into peninsular Florida, where the adults overwinter.  There is a very interesting article that you can read here, that also shows you photos of a microscopic view of their wings if you scroll down.

The brightly-colored eyespots are evolution's gift to scare away their predators.  The adult lifespan is 6 to 20 days, and during that time its food is the nectar of flowers such as tickweed sunflower, aster, gumweed, knapweed and chicory.

In the next photo I found this one on the same flowers nearby.  I didn't take a very sharp one.  It fluttered away soon after.  The closest I came to an ID was at this link, which said it was a white M. Hairstreak.  I haven't come across it before, or its name.  Hopefully someone out there will be able to confirm the ID, like last time.  I am always very grateful to my blogging friends who share more knowledge than I have.

Gregg walks on ahead of me. I am lollygagging as usual, taking photos of river snails left behind by the tide.

The information I found about them online was fascinating.  Feel free to fast forward!  They are called Mystery Snails.  It is said they got their name from the fact that during spring they give birth to young, fully developed juveniles that suddenly and mysteriously appear, while most other snails lay eggs.  They are the largest fresh water snails in the region, and can grow up to 3 inches.

  These snails can close their shells with something akin to a trap door, and survive out of the water for as long as a month. The snails feed on the algae growing on the river bottom, yet they excrete very little of the pollutants phosphorus and ammonium.  In their tissue the snails concentrate spilled oil and other toxins, a trait that makes them potentially valuable as tipsters on pollution.  When water temperatures rise above 59 degrees, a female snail starts giving birth to quarter-inch-long juvenile snails, a hundred at a time.  If pressured by predators she can reproduce at twice the normal rate.  

Females live for about five years, males for three.  They retreat to deep waters for the winter where they hibernate in the mud.  They were introduced by merchants and sailors to the West Coast in the 1890s, for the Asian food markets.  They are native to Burma, Thailand, South Vietnam, China, Korea, the Phillipines and Java. By 1911 the snails had escaped to California irrigation ditches.    

Later they were introduced in at least 27 states, especially in the northeast and the Great Lakes region, and now can be found in the Potomac River.  Demands for food, aquarium and water-garden markets helped distribute the snails across the country.  By 1960 mystery snails had found a haven in the Potomac River at Alexandria.

More information than is needed I am sure for this blog post, but I wanted to add this as I find it fascinating and always want a record of everything that peaks my curiosity.

Sadly the beach along the river is littered with plastic bottles and other debris that is washed ashore from all over.  I read on someone's blog that each time they visit this area, they take along a rubbish bag.  I thought what a good idea!  I know it seems that one person can't do much, but the next time we took a walk there I would like to bring along our own.  To my mind every little helps and I would feel a whole lot better doing my small part.

So, that's it for today.  I will be sharing Part 3 next time.

Thanks so much for visiting and I hope your day is a great one.
