I got up around 6:00 this morning, and headed over to William Land Park in search of jumping galls. Someone on Facebook had posted a video of the galls jumping around on the trail at the Cosumnes River Preserve, so I wanted to see if they were active here, too. I found some of them under the Valley Oak tree at the edge of the parking lot. There weren’t a lot, but you could see them jumping.
As I’m sure I’ve told you before, each gall is formed on the underside of the leaves of Valley Oaks and holds a single larva. When the time is right, the tree releases all of the galls at the same time (over a period of a day or two), so the ground is covered with them. Inside the fallen galls, the tiny larvae twist and flex, causing their gall to jump in the hopes that the gall will land on the earth and nestle safely under leaflitter.
Although it’s fun to see the galls jumping on the cement, it’s kind of sad, too. The problem with this particular oak tree, is that half of the galls are dumped onto the asphalt parking lot where the larvae just bake in the summer sun. They can’t jump high enough to get over the curb and into the dirt.

I didn’t see any other galls on the tree; everything seems so late this year. And I’m still astonished by the overall lack of insects I’m seeing when I’m out. I was hoping to see some sleepy longhorn bees or some caterpillars or some mantids…but nothing.
While I was walking through the WPA Rock Garden to get to the middle pond, they turned the sprinklers on. I wouldn’t mind if the sprinklers “sprinkled”, but they’re massive units that dump water on the plants like a firehose. The drops of water actually hurt when they hit me. The water also mucked up the dirt paths, turning them into slippery mud trenches.
Once I got to the pond, I was sad to see that the Sacred Lotus has now covered almost the entire surface of it, leaving little room for the ducks and geese.





I was worried that maybe the lotus seeds were toxic — and could poison the water — but that’s a problem, I guess, with the Blue Lotus, not the Sacred Lotus. I did see birds and a squirrel drinking from the water, so I guess it’s okay.
Speaking of the seeds, “…[They] can remain dormant for an extensive period of time as the pond silts in and dries out. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. Under favorable circumstances, the seeds of this aquatic perennial may remain viable for many years, with the oldest recorded lotus germination being from seeds 1,300 years old recovered from a dry lakebed in northeastern China. Therefore, the Chinese regard the plant as a symbol of longevity…”

There were quite a few domesticated ducks lounging around the edges of the pond, so I decided to try to get photos of their faces. I was more successful with some than with others. There were also a few Wood Ducks in the water; males and females. None of the males were in their adult breeding plumage.




I walked around for about 2½ hours, and I headed home. It got up to a scotching 104° today, and the air was full of smoke from the surrounding wildfires. It was hard to take a full breath outdoors.
This was hike #66 of my annual hike challenge.
