This is my first year targeting tiger beetles, what a great family! These are from northern Manitoba Canada. Thanks for any help. Tim Attachments:

I love tiger beetles in a very un-informed way. I can't ID them at all, but just wanted to say these are really nice and thanks for sharing. I collect them whenever I find them too but I usually take them to a friend for ID cause I'm lazy, maybe I can get a name for you. If no one chimes in soon I will see what I can do.
I like them a lot though, nothing more exciting to hunt in the insect world than a tiger beetle I think and so many around. There's almost always a handful of different species as you change geographic location even just a little. Catching them can take real effort, especially the species that like to hang out on big expanses of open sandy beach and such. It's kind of fun, unlike butterflies sometimes that might just require sitting under a certain tree for hours and hours until one finally decides to slow down and come into reach. Tiger beetles you can really stalk, like a real hunter.

I believe this to be the Cicindela limbalis. I am quite new at this though so my thoughts should be taken hesitantly. Bugguide.net pointed me in this direction, but since it is based only on US bugs, I did a Google search of the range and it seems to match up.
Hopefully someone more knowledgeable than I will chime in and tell us if I am correct or not.

I bet John Acorn could nail that from 100 yards away, with his eyes closed. I cannot. Where is he?

It's Cicindela purpurea, maybe ssp. auduboni.. I've collected it in Illinois a number of times.

this is C. Limbalis. The Cicindela purpurea audubonii is more green and dont have the upper dot on the elitra.

Colour and the presence of the shoulder mark are not reliable for separating C. limbalis and C. purpurea. C. limbalis can be greenish in the NE US and northern Canada, C. purpurea is red in the eastern US. Some populations of C. purpurea have the shoulder spot and some populations of C. limbalis lack it. The shape of the middle band is a better way to distinguish them, C. limbalis has a sharper bend.
I've collected a few hundred C. limbalis in northern Manitoba and the specimens shown here are typical C. limbalis. I've seen specimens from the Gillam, (which is as far as the roads go in NE Manitoba), and some specimens are a greenish red and lack the shoulder mark, or it is very small, but they are still clearly C. limbalis.

True, that's why I brought up C. purpurea, because many of mine have a humeral spot on the side of the elytra, and some of my limbalis don't. In fact, I have one that is almost entirely unmarked except for a marginal band.
So, you have to key them out and think a little bit about these two species.

Thank for all the help guys, I really appreciate it as this is all new to me, and a book only goes so far. I agree that they are C. limbalis. They were collected on a red clay bank too. Attached is what I believe to be C. purpurea audubonii. Sorry for the poor picture quality, new camera, now I have to start learning all over again. Tim Attachments:
