Contact the U of A Biology Department
I sent two emails to the U of A Biology Department fairly recently and received prompt responses with lots of supporting information for the two spiders I have attached.
This one is called: A. gemma
This one is called: A. saevus. I found that this spider (.... all spiders ?) fluoresces at night using a camera flash. :Cool:
This is the link to the U of A Biology Department:

Send them your picture in an email.
A quick search using "Spiders of Alberta" brings up lots of good hits.

How long has it been sitting there for? Was it fresh or dried out?
It's hard to tell size from a picture, need something in the shot for comparison but the markings cry wolf.
I've always been fascinated by peoples fear of spiders. Not saying that to put anyone down, I just don't understand it.

I'll give you that, they are kinda creepy but i'm fascinated by them. Love interacting with jumping spiders, my fav. I get a kick out of the girlfriend, no fear of them at all, will pick them up and give them a friendly eviction.

I get the same type of spiders at my place in the East Kootenays. When you get a positive ID, I'd appreciate you letting me know!
Thx
Here's a photo of one of my guys..

First guess would be a giant house spider, but there's no size comparison. Do you have a better pic looking down so we can see the markings on the back and abdomen?

Jewel spiders, the first is called the cat spider. Usually have a few kicking around the balcony ever year, haven't seen one this year. Disappointing.
Watch them build a web, pretty cool.

Well I emailed the University that a member provided a link to. They are leaning towards hobo spider, sending them more pictures as requested and they even asked if I could send the spider to them. Good thing we are moving anyways, this is a pretty old home we are renting, lots of places for spiders to hide

I got bit on the finger by one in Cameroon and my whole hand swelled up like a balloon. I still don't like spiders.

Ok, phew, I sent more pictures and this is what they said
Quote:
Yeah, I think it is Agelenidae, Tegenaria agrestis. This is one of several very common agelenids that have been imported unintentionally from
Europe and UK. The 3 very common species in western Canada and the northwestern part of the US are Tegenaria domestica, the common house
spider that is present in most basements, and Tegenaria duelica (=Tegenaria gigantea) if you are checking out the internet.
Tegenara agrestis received bad name because of one guy who did faulty experiments, and then reported that this spider causes necrotic lesions.
It does not cause them, and multi-experiments to confirm what Darwin Vest did have all come to naught. In its home European area, it is not known
to carry a toxin or dirty fangs that will cause necrosis. The name "agrestis" means rural or of the farm.
To put these spiders on a frequency scale, T. domestica is everywhere in the world, T. agrestis is not very common in Alberta, and so far, we have found
T. duellica fewer than 5 times in Alberta. It is more common in the Vancouver-Victoria-Seattle areas.
All 3 species are really good at cleaning up pests in your basement or wherever.

Eratigena atrica - giant house spider. Used to be Tegenaria genus.
*Could* be Tegenaria agrestis, the hobo spider, depending on your locale.
Either way, nothing to be concerned about.
There is some necrosis at Tegenaria agrestis bite sites, but it's poorly documented and seems to be largely blown out of proportion.

Im in Dawson Creek, not sure if that helps. How do you narrow it down hobo spider or house spider?

It's getting to the time of year when I'm starting to see them around some of the houses I work on...seen a couple really big fat ones already.

micro jumpers
I haven't noticed any around for a while, but in June/July there were a few really tiny jumping spiders around. Size wise, about 8-10 would fit on a penny and they were dark gray/black with light yellow markings. I couldn't get a good picture even with my camera on macro but they were definitely jumpers as they would jump back from a finger approaching and hunt flies on the window sill.
I'll look for an ID online...

Hodo spiders will have a little bag on a stick over their shoulder.

Got 4 of them on my balcony at the moment, they hide under the rails by day and are out at night. Interesting little buggers, 2 of them are fairly small but growing and have a good tolerance for cold. They easily survive frosty nights.
