Tabatha Yang and her six-month-old son, Karoo, were sitting on their lawn last Sunday at their West Davis home, when she saw red. Literally. One minute they were enjoying the springlike weather, and the next minute his head was covered with bright red dots. Looking closer, she spotted a tiny insect in his eye, which she quickly removed. Then her legs began to welt and itch. They had just encountered no-see-ums, tiny Valley Black Gnats that feed on......

Watching the golden bees forage amid the brilliant red blossoms in the late afternoon is a delight to see, especially when the sun backlights them. The ancient fruit, native to Iran, is one of the world's first cultivated fruits. Thankfully, it is now "trendy" in California, with some 30,000 acres of pomegranates in production. We treasure its ruby-red kernels, tart flavor, and high antioxidant content. Since ancient times, the fruit has......

The ladybugs were also searching for mates. The......

We saw this jumping spider (family, Salticidae and probably genus Phidippus) in our flower bed last weekend. Perched on a pink petunia, it waited for dinner, its four pairs of eyes surveying the floral menu; its rear legs poised to jump; its front legs ready to grasp unsuspecting prey.
