Which beneficial insect is well known for predating aphids in crops?

• A. Honey bee
• B. Praying mantis
• C. Green lacewing
• D. Lady beetle

Answer: (D)

This question tests understanding of which beneficial insect is most closely associated with preying on aphids in crops. Lady beetles are renowned aphid predators; both the adults and especially the larvae feed voraciously on aphids, helping to suppress their outbreaks in fields and gardens. Their feeding behavior provides quick, noticeable pest reduction, and their life cycle tends to align well with aphid population booms, making them a reliable biocontrol ally in integrated pest management. While green lacewings also consume aphids (notably their larvae), and praying mantises are generalist hunters, the strong, widely recognized link between lady beetles and aphid control makes them the best-known choice for this role.
