The three submarginal cells in the forewing of Halictidae create what shape?

• A. Bow
• B. Heart
• C. Circle
• D. Square

Answer: (A)

The key idea here is wing venation patterns and how they form recognizable outlines on the forewings. In Halictidae, the three submarginal cells are arranged so that the boundaries created by the surrounding veins produce a bow-shaped silhouette along the wing margin. That curved, arched outline is a distinctive feature of these bees and helps distinguish them from other groups.

Why this shape fits best: a bow-like outline reflects the smooth, curved junctions of the veins that define the submarginal cells in this family. The other shapes—heart, circle, or square—would require different vein configurations with more pronounced lobes, a closed loop, or right-angle corners, which aren’t present in this arrangement.
