The tender shoots of fava bean blossoms are attracting scores of aphids, which suits the ladybugs just fine.
Nothing like an all-you-can-eat aphid buffet.
The aphid population is growing rapidly. And the ladybugs, aka lady beetles or ladybird beetles, are trying to keep up by (1) increasing the population and (2) increasing their voracious appetites.
Good thing, too!
The ones we saw in the haven today were the seven-spotted ladybugs. Of the more than 5000 described species in the Coccinellidae family, more than 450 are native to North America.
Gary Zamzow of Davis, one of the volunteers at the haven who keeps the site looking beautiful, says he sees the seven-spotted ladybug and the 12-spotted ladybug a lot in Davis. He hopes that the Harlequin ladybug doesn't take over.

So, the next time you see a ladybug, see what it is.
