Crayfish - Orconectes virilis

Crayfish - Orconectes virilis
Ledges State Park, Boone County, Iowa, USA
August 6, 2011
Size: 80mm
Red tips of claws.

Moved from Crayfishes.

Confirmed ID as species Orconectes virilis (juvenile) after reviewing original full size image via email correspondence.

ID based on location plus appearance of rostrum/acumen (with marginal spines), presence of cervical spines, chelae and open areola.

Other photos?
You don't happen to have any other photos of an up close view of the carapace/rostrum do you? I can't quite tell if there are marginal spines at the base of the acumen or not.
