Which statement correctly describes birch leafminer larvae?

• A. Adults are black and resemble small wasps.
• B. Larvae are translucent yellowish white.
• C. Systemic pesticides usually applied to control.
• D. Damage plants by feeding on leaves.

Answer: (B)

Birch leafminer larvae are the pale, worm-like stage that actually feeds inside the leaf tissue. They are translucent yellowish white, which is a distinctive description you’ll see in field guides when diagnosing mined birch leaves. This pale color makes the larva recognizable even though it’s living inside the leaf. The other statements refer to aspects outside the larva itself—the adults’ appearance, management methods, or the fact that the pest damages leaves—so they don’t describe the larval form.
