Plentiful along the Grand Forest trails
Velvet ant
Seen forming dense clumps throughout the lawn area of De Anza Park, Sunnyvale. This is a widespread non-native found in lawn areas throughout the park. Note broadly elliptical leaves with short petioles and candle-like inflorescences consisting of tiny, nondescript flowers. The flowers are really little more than bracts with anthers and stigma exserted from them.
Waterlogged, perhaps explaining the paler color. It was growing by the base of a coppiced oak and was rather large, 30 or 40 centimeters ( see second photo)
small blue butterfly, around the size of a dime, was it drinking the moisture? didn't get a good look at the upperside of wings.
thinking back there definitely were lupines nearby
