On Valley Oak (Quercus lobata).
This spider likes to put her web right in the way of my face. After running into it 3 times, I think she's learning.
According to the sign, these abundant and regularly-spaced knots on the branches of California-grown quince trees are bacterial galls. Found an old book describing them and saying the cause wan't well-determined yet:
Lots of these in the zinnias.
Going nuts in a California Poppy. Really pollen-y abdomen underside.
On a zinnia.
Multiple bees per dahlia flower.
A few of them going in penstemon flowers.
Not sure what this is. Growing on my fence and trees as a vine. Most leaves around this size.
Ivy planted many years ago and now not willing to leave (pun intended).
Found in the lawn at Montgomery High.
Found in my lemon tree.
Sitting in the bud of a sunflower.
Sold widely as an excellent nectaring plant... I find that it demands a lot of water or it will promptly wither; and sadly, doesn't really seem so attractive to local butterflies. Perhaps others have had more luck.
Vine growing like crazy. We've tried to kill it but it always comes back! Shown growing up the side of one of my sunflower stalks.
Growing out of a crack in the sidewalk. Surrounded by a dandelion plant. Blossoms about 2.5 to 3 inches wide.
