What kind of jumping spider is this?
She has gold as caraspace, and the abdomen as well, some shine on her legs as well, very beautiful spider!

also, what kind of spider is this?
this one is a male.

thanks for any info!

The second looks to be a Tibellus sp. if my memory is correct...

Crysta · Jun 9, 2010

that's one! although I can't find the right sp, but i have the name of running crab spider as well!

The second spider might be Tibellus oblongus (two black dots at the rear of the abdomen), but some different Tibellus species appear so much alike you have to check the palp or epigyne to be sure which one you're looking at.

Here's an adult T. oblongus female I found in Alberta (ID'd by the epigyne):

For the jumper, I scoured through all the different families. Closest I could get was Eris, but it doesn't scream it. I can't find any other species that looked more like it though.

J solen it seems to be your species there, but mines a male. What is a epigyne?
here is another picture of the girl

No problem.

Here's an adult male T. oblongus (identified by the palp):

CentipedeFreak said:
What is a epigyne?

An epigyne is a sclerotized (usually) organ into which the male introduces his sperm and through which the female later lays her eggs. It's located approximately between the booklungs on the underside of the abdomen.

Here's the underside of a Tibellus maritimus, showing the epigyne:

The epigyne is different for each species. For example, compare the epigynes of Tibellus oblongus with Tibellus maritmus:

T. oblongus:

T. maritimus:

Your spider is an immature male, so it would have to be identified by its palp after it matures.

[edit - I just looked at the most recent checklist of Canadian spiders (May 14, 2010), and T. oblongus and T. maritimus are the only species of Tibellus found in NB.]

Crysta · Jun 10, 2010

wow thanks for the ID!!! I can't find pictures of maritimus online but oblongus seems pretty close! I need to get out and take more pictures of spiders haha! thanks for the info once again! btw, where did you get the checklist of canadian spiders?

I've got some T. maritimus pictures online, but they are only of a faded, preserved specimen (that's where the epigyne came from). I hope to find another one this season and replace these pictures with live shots:

A picture of a live adult female T. maritimus can be seen here (it looks very much like T. oblongus - compare it with the female pictured above):

It's available online:

Ill be sure to take pictures if I see another one, and send it to you. Or I can capture a spider for you if you would like.

Thanks for the links as well!!

Malhavoc's · Jun 11, 2010

any luck on the jumper, a friend of mine just asked me about one that looks about the same figued I'd come see if you got it ID'd before I start lookin

Crysta · Jun 11, 2010

nope not yet! i found a small baby of the same species yesterday as well, at least i think its the same ill post a picture later.

Malhavoc's · Jun 11, 2010

I was doing some light skimming, I didnt go indepth into this sight, however they are apperently working on an identification key for canadian found salactids.

That's a good project, if it's still in the works. Until then, jumpers can be keyed to genus using several keys, including Spiders of North America. From there, species keys for the genera are available in various papers and other publications spread out here and there. You have to hunt them down (which, for the most part, I haven't done.

I haven't paid a lot of attention to jumpers up to now, except for the more common ones in my area).

Here's one of the better online resources for identifying salticids:

I will probably be able to find one around my area, but thanks! However, if you ever find other spiders you can't ID and want me to try to identify them for you, drop me a PM and I'll tell you how and where to ship them. I can't guarantee I'll be able to ID 100% of them, but should be able to do most of them. They need to be adults so I can check the epigyne or palps. I might be able to ID the jumping spider, for example, if it is an adult. It looks like an immature, but a picture of the underside would help to decide on that.

Crysta · Jun 11, 2010

ill be sure to take pictures of the underside next time I come across the species! take my handy ziplock bag with me haha!
We have some purple orb weavers here as well. (like those bright pumkin orange ones, but purple) i'd like to find them again, amazing colors!

jsloan · Jun 11, 2010

Was it like this one (Araneus marmoreus)?

Crysta · Jun 11, 2010

nope not quite like that, there was no black spot in the back of it, all purple with white going through it, more like this, actually almost exactly, but a more solid purple going through it.

BTW, how do you submit images to that website? I can't figure it out. lol

ZergFront · Jun 11, 2010

The jumper looks like a Paraphidippus but I don't know what their range is. Here's some pictures I found.

BTW - If anyone can send some to the US, PM me. I've been wanting to buy some of these for a couple months!

here a young one. The head is pretty shiny and doesn't have it's green yet.

Nice. I haven't seen one of those before.

Here's a help link that tells you about it. It took me a few tries before I got the hang of it, but once you get used to it it's pretty straight forward:
