Approximately how many mosquito species exist worldwide?

• A. 300
• B. 3000
• C. 30
• D. 1500

Answer: (B)

Mosquitoes form a highly diverse group, with a large number of species described worldwide. The widely cited estimate is about three thousand described species in the mosquito family across all regions and habitats. This reflects extensive taxonomic work, and the count continues to grow as researchers explore under-sampled tropical areas and apply genetic methods to distinguish cryptic species that look very similar but are biologically distinct. So, around three thousand is the best general estimate for global mosquito species richness. The other numbers are far less representative of the true diversity. Three hundred or thirty would vastly undercount the variety observed across continents and ecosystems, while fifteen hundred underestimates the diversity most taxonomists recognize today.
