What type of mosquitoes are these?

Hello Everyone, please see attached photos of mosquitoes. What type of mosquitos are these. Are these dengue mosquitos?

I'm no entomologist but they do look like Aedes aegyptii (that carry dengue, yellow fever, etc). https://en.wikipedia.org/wiki/Aedes_aegypti
there is a marking on the thorax that I can't really see.
Our rule here is to assume that all mosquitoes are aedes and do our best to keep them out.

Hmm I see. Well it resembles more like Aedes Albopictus https://en.m.wikipedia.org/wiki/Aedes_albopictus

Entirely possible. But both types carry dengue, yellow fever, zika, etc.
