Which family is commonly known as seed bugs?

• A. Lygaeidae
• B. Coreidae
• C. Pentatomidae
• D. Tingidae

Answer: (A)

Seed bugs are a group of true bugs that specialize in feeding on seeds. They use piercing-sucking mouthparts to extract nutrients from seeds, often found on seed pods or in dry fruit. The family Lygaeidae is commonly known by this name because its members predominantly feed on seeds, making seed-feeding the defining trait people associate with them. You’ll often see familiar seed-feeding lygaeids like the large milkweed bug in the field, feeding on seeds rather than plant tissues. In contrast, the other families have different well-known names and typical diets. Coreidae are the leaf-footed bugs, which are commonly plant feeders on stems and leaves and have distinctive leaf-like hind legs. Pentatomidae are shield bugs or stink bugs, usually feeding on plant sap and sometimes seeds, but their common name reflects their shield shape and odor rather than seed specialization. Tingidae are lace bugs, small sap-suckers often found on the undersides of leaves with ornate, lacy pronotum and wings. So the best match for “seed bugs” is the family known for seed-feeding habits, Lygaeidae.
