💡

Did You Know?

Colonies on tree bark produce so much honeydew that it rains down onto cars, sidewalks, and outdoor furniture, creating a sticky nuisance in urban areas.

Cabbage Whitefly

A small white-winged insect that infests brassica crops, weakening plants with sap feeding and honeydew production. Populations have increased dramatically in European cabbage and kale crops.
