You may see leafhoppers in your garden or landscape this time of year as they hop about feeding on a variety of plants. You can distinguish these small, wedge-shaped insects from other pests by their tendency to quickly jump or crawl rapidly sideways when disturbed.
Leafhoppers are sucking insects that insert their mouthparts into plants and suck out plant juices and cell contents. Damage occurs during feeding, which typically results in leaves looking stippled (little white dots), bleached, pale, or brown, and plant shoots may curl and die. You may notice a sticky residue on the plants called honeydew, a waste product from when some species of leafhoppers feed. A fungus called sooty mold may grow on the honeydew, which can be...

“I hate crabgrass!” is a common lament I've heard from residents during my 35 years as a UCCE Weed Science Farm Advisor.
