Anopheles mosquitoes are mostly active at dusk and night.
Tips
usage
Distinguish from 摇蚊 (midges, harmless chironomids) — only Anopheles mosquitoes transmit malaria parasites (疟原虫). 疟 itself means 'malaria'.
memory
疟 (malaria) + 蚊 (mosquito) = the mosquito that brings 'the shakes' — 疟 pictures 疒 (sickness) over 虐 (cruel), capturing the old name for malaria: 打摆子 (the shaking disease).
