Input on jumping spider ID?

[ozzymandias]

Hi all,

I have a friend who knows how much I love spiders and so sent me this photo for an identification. I don't know much about the Salticidae family so my best guess is a female from the Colonus genus, maybe C. sylvanus. Does that look right, or does anyone else have input? The specimen in question was photographed in southern Ontario.

Compare with Maevia inclemens. The Colonus genus doesn't occur north of the lakes (though it could have been introduced).

Thank you so much for your input! The geographic location was one reason I was doubting my Colonus identification.

The Colonus genus doesn't occur north of the lakes (though it could have been introduced).

That coincides with an article I read the other day about how global warming and human contribution has species breaking natural barriers all over the world. Among the examples given were aedes mosquitoes, low land day active turning up at 9000-11000 ft. elevations active up to 23:00.

Similar story here in Poland - the mountains in the south are a barrier but not an impenetrable one. While we're still waiting for the first confirmed record of Aedes albopictus, another mosquito species (A. japonicus) has been confirmed in 2023. Plenty of invert species change their distribution range over a single year or just a few.

We are rewriting the planets natural history in our image, turning it into a horror story filled with unpredictable ramifications. One of the most concerning is vector and potential vector species relocation turning the general immune systems into knee jerk responses based solely on reactionism without mom nature's slow trial and error.
