Q.What is this on my Verbena?
Just found this on my Verbena this morning. When using a magnifying glass, it shows there are clusters of these tiny yellow oval things. They are loosely wrapped in a white web-like, powdery substance. On down the leaf there are singular tiny yellow oval things. A clump of English ivy next to it was thriving several days ago but died. These plants are in a pot with a geranium.

These look like mealybugs, a type of scale insect that often infests Verbena. The little yellow ovals are its eggs. See the following article for help:
