Eggs are generally unreliable for classifying mosquito species. Which option best states this concept?

• A. Always reliable
• B. Never used
• C. Generally not reliable
• D. Always unreliable

Answer: (C)

The main idea is that eggs don’t provide dependable clues for identifying mosquito species. In many species, eggs look very similar, and their appearance can be influenced by the environment, so you can’t rely on them to tell species apart. Identifying species typically requires examining the larvae or adults or using molecular methods, not just the eggs. So saying eggs are generally not reliable captures the common, practical approach: eggs are useful for detecting presence and oviposition activity, but they aren’t a trustworthy basis for species-level classification. The other statements are too absolute: eggs can sometimes be linked to presence but aren’t universally diagnostic, and they’re not always unreliable in all contexts.
