What magnification is recommended for a hand lens used to identify insects?

• A. 3 Power
• B. 5 Power to 10 Power
• C. 15 Power
• D. 40 Power

Answer: (B)

Seeing enough detail to identify insects reliably requires a hand lens that balances detail with a broad view. If the magnification is too low, you won’t be able to discern diagnostic features such as wing venation, body segmentation, or antennae structure. If it’s too high, the field of view becomes very small and depth of field shallow, making it easy to lose the specimen or miss the overall shape while you chase fine details. A middle-range magnification gives you a practical compromise: you can inspect key identifying features clearly while still keeping most of the insect in view and maintaining a comfortable working distance. This balance makes it the recommended choice for field identification with a hand lens.
