Nothing killed my dream of a private island in Alaska quite so fast as elephant mosquitoes[0]

[0]: https://en.wikipedia.org/wiki/Toxorhynchites_rutilus



>Tx. rutilus feeding behaviors make them strikingly different from a typical mosquito. Both adult males and females are strictly nectar-feeding and so they do not have a role in the transmission of pathogens to animals as in other mosquitoes.[7] Instead, their larvae are predacious and could potentially help curb the spread of diseases via vector mosquitoes. While they commonly prey on copepods, rotifers, ostracods, and chironomids, they also generally have a preference for certain species of mosquito larvae including common disease vectors such as Aedes albopictus, Aedes aegypti, and Aedes polynesiensis.

what's the issue?


The wikipedia article you linked to says that the adults of that species feed only on nectar and do not suck blood.


... and have a range largely in the south-eastern United States.

Which isn't quite where Alaska is located.


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


Honestly, I was so confident in what I thought I knew (namely evil giant Alaskan mosquitoes) that I didn’t bother to read the article I linked, I just added it for others’ context. Culiseta alaskaensis is probably the source of confusion, and I think a switch-up happened when this was first relayed to me. Looks like the island might be back on, assuming it doesn’t get hot enough to become temperate in the next few years hah.


In my experience Black flies[1] and no-see-ums[2] are far worse (not counting mosquitoes born disease). It's like a massive angry cloud of micro horseflies that intend to dismember you bite by bite.

The Blackfly song has it right then? Thank you National Film Board of Canada: https://www.youtube.com/watch?v=f389hIxZAOc


Pretty much - although after living with it for 4 year I can report it's often worse. =) The local bookstore gave a discount for the first bite of the season if you lived long enough to collect.


FWIW black flies are also disease carriers.


While technically true, I think that's in tropical Africa. Are there also diseases that they carry in North America? Even without disease, I tend to agree with the OP that black flies are worse than mosquitoes, and don't think I've ever heard of anyone getting a disease from a black fly bite in the US or Canada.


You're mostly correct, but apparently not totally :) - I did think that it was further north, but the human cases are usually only in south and central america and africa. Nonetheless, there are some.

https://www.merckvetmanual.com/poultry/bloodborne-organisms-... (birds only, but still north american disease)

There's also an allergic reaction apparently due to large numbers of bites called simuliotoxicosis / black fly fever.

There's also this mysterious one in europe. https://pmc.ncbi.nlm.nih.gov/articles/PMC7920075/

Aaaand there's this site claiming possible encephalitis transmission, although I kinda feel I'd prefer a better cite than that. https://www.mosquitomagnet.com/resources/faq-black-fly-other...


Yeah, they can, I was just commenting on the physical experience as to which insects would keep me away from the northern latitudes.
