As far as I know, southern Alberta only has one species of giant water bug (Lethocerus americanus).
The insect that I collected appears to be an immature giant water bug without fully developed wings. In the identification key's my college has access to, one tarsal claw on the forelegs is the main distinguishing characteristic. However, my sample has two tarsal claws on each foreleg.
My research as to what species it could possibly be has been continual dead ends. If anyone has any suggestions on a species it could be or just a genetic mutation, they would be greatly appreciated.
