October 2011

You could say that October comes in like a lamb and goes out like a lion.  It's the month with the greatest temperature change, and this was particularly striking this year, since we ended up the month with temperatures historically normal for January.  Yet the leaves didn't begin changing here in the Piedmont until about October 11, and a full complement of arthropods was present in the area at the beginning of the month.  Of the typical summer arthropods in my urban neighborhood, the holdouts were tiny members of the Phidippus clarus jumping spider species, although other jumping spiders (Hentzia mitrata) lasted until the latest cold spell.  

Over on the Jordan Lake mudflats, the insect holdouts were Hydrophorus-genus long-legged flies which skated along a small stream connecting the lake with an inland pond with abundant water primroses.  Meanwhile, the Valley Redstem wildflowers, originally green with pink flowers, produced berries, turned red and collapsed while the prevalent False Nutsedge turned brown and remained standing.

This was a chilly morning, about 45° F.

Small arthropods were regularly visible on the yellow bollards: these three species were the most common.  Small field crickets made brief appearances on the trails.  The large snail was a surprise.

Jordan Lake Gamelands (near NC-751 bridge), Chatham County, NC  10/26/11

This is my favorite natural area in driving distance of Durham because of the large mudflats that occur during the droughts.  You aren't confined to trails in the woods, unlike in nearly all public-access natural areas.  There are large stretches of ground crowded with a large variety of small plants without any nuisance value, although you can pick up "stickers" in the bushes closer to the woods.  False Nutsedge and Valley Redstem are the biggest of these, while most others lie close to the ground.

Duke Gardens, Durham, NC  10/25/11

This day I heard the Black-bellied Whistling Ducks actually "whistling."  It was a high, quavering sound.

Monarchs showed up by the dozens, but there were many other butterflies there, too.

This was the second day that yellow leaves showed up.  It was a sudden transition.  This turtle had apparently come up the hill to escape the steady rain, but it had been consistently light.

Flat River Impoundment, Mangum, Durham County, NC  10/10/11

This was a mild, very windy day.  The water was very low, but covered with duckweed.  No migrating birds appeared, although several Northern Mockingbirds were sitting in one tree.

A Jordan Lake Gameland (near Rte. 751), Chatham County, NC  10/9/11

Because of the prolonged drought this year, the mudflats were unusually large.  Fortunately, a small stream led from the woods through the mudflats to the lake, making it easy to observe the stream's aquatic fauna.  On the other side of the trail leading to this area through the woods from the highway was a pond full of water primroses.
