Good point. I wonder if they'd heard about huge mosquitoes up north and just looked for first wikipedia article about large mosquitoes.

Maybe they were thinking of this one. https://en.wikipedia.org/wiki/Culiseta_alaskaensis

This one had a large size and was a blood sucker, but wrong side of the continent again. https://en.wikipedia.org/wiki/Psorophora_ciliata
