Scientific Name
Leptoglossus phyllopus
Biology
Leaf footed bugs have sucking piercing mouth parts. They can cause significant losses in sorghum because they feed directly on the developing kernels or other parts of the head. After feeding, the damaged seed is more likely to be affected by fungi or other plant diseases.
