I just returned from Viques; an island next to Puerto Rico. The place is known to have both Dengue and Chikungunya, both spread by Aedes ageptyi. I walked around the island looking for places where the mosquitoes lay the eggs. I was not expecting this; but I stumbled upon mosquito larvae happily feeding in a tidal pool. Initially, I did not believe that (how can mosquitoes survive the salt water of the tidal pool); but soon I had no choice but to believe it. I collected the water and the mosquito larvae which I kept alive in my room for 4 days in a row; with no reduction in activity.

Here I recorded a live larvae moving around inside the foldscope; also my commentary is captured. Thanks Thomas for your acute questions – it was really fun.

The larvae are almost clear; and beautiful tracheal structures are visible inside the head. The eyes are very clear and the siphon is visible. Also since the larvae was alive; you can clearly see the pulsating beating heart.

Find mosquitoes around your community and post them here.

cheers
