Aphids, don't you just hate them? Especially those oleander aphids that suck the very lifeblood out of our milkweed plants that we're struggling to save for monarch butterflies. Just call aphids "The Enemy of the Gardener" or "The Enemy of the Milkweed." The University of California Statewide...

Redhumped Caterpillar: Aptly Named

You've seen them. You've seen them hop. They're aptly named. Leafhoppers are tiny insects (family Cicadellidae) that suck nutrients from plants. But have you ever looked at them really closely? We spotted scores of mottled leafhoppers last week on our  Salvia mellifera (black sage) and...
