What are Aedes aegypti?

Aedes aegypti are a type of mosquito, sometimes called the yellow fever mosquito, known for carrying viruses like Zika, dengue, and chikungunya. They usually thrive in tropical and subtropical regions. Their recent discovery in London, though larvae were destroyed, highlights concerns about how climate change might allow these insects to establish themselves in new, previously cooler, environments.
