Red Sunflower seed weevils are active in South Dakota. South Dakota State University Extension Entomology Field Specialist Patrick Wagner says the pests are widespread. “Now that we’re at full bloom, they’re the most active.” The weevil can be found on the head of the sunflower. “In some fields, you can see the weevils walking across the flower. There’s a couple types of weevils on sunflowers, but the red sunflower weevil will have that rusty color.”
