Life Cycle and Behavior

The life cycle of the sunflower beetle is generally characterized by a single generation per year in many regions, such as ManitobaSunflower Beetle (Coleoptera Chrysomelidae) Pattern of Adults overwinter in the soil and emerge in May, precisely when the first available sunflower foliage appearsSunflower Beetle (Coleoptera Chrysomelidae) Pattern of Mating occurs shortly after emergence, followed by egg-layingSunflower Beetle| Sunflowers | Crop Pests | Insect Information | Extension | Entomology | Kansas State University. The sunflower beetle larvae, upon hatching, immediately begin to feed voraciously on the foliageSunflower Beetle| Sunflowers | Crop Pests | Insect Information | Extension | Entomology | Kansas State University.
