Milkweed Bug vs Stink Bug: Key Differences in Appearance and Behavior #3386250 (License: Personal Use)

The left image shows a milkweed bug (Lygaeus kalmii), notable for its bold red-and-black patterned body and slender antennae, commonly found on milkweed plants where it feeds on seeds. The right image features a brown mottled stink bug (Halyomorpha halys), an invasive agricultural pest with a shield-shaped body, speckled brown exoskeleton, and banded antennae, often seen on crops or structures. Both belong to the order Hemiptera but differ significantly in ecology, coloration, and impact.

This comparative image is used in entomology guides, pest identification resources, and educational content to help gardeners, farmers, and students differentiate beneficial or native bugs from invasive pests. It supports user intent for visual ID, species comparison, and ecological awareness.
