Hi, I need some help to ID this baby crayfish i caught in a Michigan inland lake.. The body is a pale blueish/gray and at the end of each claw is a blue color and then the tips are a orangish color.
Any ideas????
Thanks!!

Looks like a Rusty to me. O. Rusticus
This is a new invasive species to this part of the country. I just collected a bunch in upstate NY and they are not suposed to be here either. Very agressive and disruptive to the aquatic environment.

Looks like orconectes virilis. I find these here in Kentwood, in Kent County. The orange tipped claws are common in o. virilis, but not guarenteed. But I do see the red lines between the tail segments, that's indicative or o. virilis. Do a search on Google images for more o. virilis.
Shade and pattern of the shell varies a lot depending on their environment. I see some that are dark and some that are light coming from the same pool. So I use:
- Lack of rusty spot on side to rule out O. Rusticus
- Orange tipped claws to determine O. Virilis
- Thread thin red lines between tail segments, and on end of tail, to determine O. Virilis.
