Mount Diablo hosts large congregations of ladybugs in winter. Perhaps you've seen them? Masses of writhing, reddish-orange beetles in a shady canyon? It can be an arresting, even creepy, sight. Which is all part of their clever survival plan.

Oak Mistletoe

Ah . . . fall on Mount Diablo! Golden grasses, auburn chamise, and bare deciduous oaks. But wait! Some of the oaks' branches are festooned with a green, beach-ball-size plant. The Druids considered it the soul of the tree. But the real story is more complicated!

River Otters of the Mount Diablo Watershed

Wally De Young

River otters on Mount Diablo?
No, but join Wild Mount Diablo and explore how the mountain's many headwaters feed the creeks and canals of the watersheds below, providing river otters and other water-loving creatures with essential habitat.


Everyone loves our State flower, the California poppy! But few know the story about how it got its scientific name. It starts with a Russian ship sailing into San Francisco Bay with a German poet on board ....and the rest is (strange) history.
