I got up around 6 o’clock this morning and went over to the American River Bend Park for my walk. I was looking for summer galls and found ‘em, so my trip was fruitful. I found Red and White Cone galls, Spiny Turbans, Yellow Wig galls, Spangle galls, ash tree galls, willow galls, Woolybear galls, Live Oak Round galls, Flat-Top Honeydew galls… and this is just the start of the season. Sometimes there were several different galls on the same leaf or stem.
The wasp larvae inside the Flat-Top Honeydew galls produce honeydew that exudes through the surface of the galls. The tree gets no benefit from it, but the honeydew attracts ants and wasps that in turn protect the larvae from parasites that might otherwise prey on them. I also found some Yellow Jackets feasting on some dead thing, and a lovely Green Lacewing sitting on a leaf… As for other critters, I got to see a Great Blue Heron, some female Common Mergansers resting on stones in the water, and a young male coyote. He kept moving from bright sunlight to shade among the trees, but I did get a little video of it.
