Which family has a cuneus on the fore wing?

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

Answer: (A)

Forewing structure in true bugs includes a triangular wedge at the distal end called the cuneus. In plant bugs, this cuneus is a clear, well-defined triangular patch on the fore wing, situated near the tip and separated from the rest of the wing by the clavus. This wedge-shaped area is a diagnostic hint that helps identify the family Miridae. Other families in the list don’t show this same distinct triangular patch: lace bugs have wings that are highly reticulated and lace-like without a pronounced cuneus; leaf-footed bugs have a different wing pattern with broader, less defined divisions; seed bugs have their own venation that doesn’t emphasize a solitary cuneus. Thus, the presence of a defined cuneus on the fore wing points to Miridae.
