A light rainstorm strikes the garden, pummeling and shredding some of the blossoms.
As the rain lets up, a honey bee buzzes into a rock purslane blossom for a sweet shot of nectar.
She is not alone.
If you look closely, you'll see three green aphids on an unopened blossom next to her.
There are, entomologists say, about 450 different species of aphids in California.
One specie found the rock purslane (Calandrinia grandiflora).
Score: Beneficial insect: 1. Destructive pests, 3.
Aphids and Honey Bee
The important work that soldier beetles (family Cantharidae) do is never more exemplified than in the "before" and "after" photos.
When the aphids landed on our rose bushes, a few ladybugs came to dine, but the insects that really stopped the aphid onslaught were the soldier beetles.
Veni, Vidi, Vici! They came, they saw, they conquered.
And now, since their food source is gone, the soldier beetles have flown off to find another tasty smorgasbord.
Yesterday we spotted only one soldier beetle (genus Podabrus) on a rose bush. If you look closely, you'll see why there's only one.
Look ma, no aphids!

Insects are cold-blooded so their temperature coincides with their environment.
Before the sun rises, they lie ever so still. As the sun warms them, they stir ever so slowly.
At 6 a.m. yesterday, we checked the roses for aphids (yes, they were there) and so were the predators: the soldier beetles and ladybugs.
A soldier beetle crawled to the edge of a leaf. A ladybug cartwheeled over a leaf and then clung to the tip.
Breakfast is ready!

They're good soldiers, those soldier beetles.
Members of the family Cantharidae, they are beneficial insects that eat other insects, especially aphids and caterpillars--but just about any soft-bodied insect will do. If no insects are available, you'll see them dining on nectar and pollen.
We saw these soldier beetles, with their long, narrow reddish-orange bodies and brownish-gray wing covers, on our rose bushes this morning.
As aphids scooted up and down the steps and leaves, so did the soldier beetles. Three formed a "troop" in a three-gun salute.
California is fortunate to have more than 100 species of these "soldiers of fortune." They're also called leather-winged beetles or leatherwings. Check out their long, threadlike antennae.
If you see soldier beetles in your garden, savor them. They're the good guys.
Please pass the aphids.

AphId in Flight
In a matter of days, the aphids discovered our newly purchased rose bushes.
They clustered around the buds and unfolding leaves, piercing the tender stems and sucking the plant juices as if there were no tomorrow.
For some of them, there would be no tomorrow.
A ladybug arrived and began feasting on the colony of aphids, like a 10-year-old kid with a bag of french fries from a fast food place.
She gobbled the aphids and then, satiated, off she flew.
With spray from a garden hose, we knocked the aphids off.
Something tells me the aphids will be back.
But so will the ladybugs.
