Someone(an avid ice fisherman) was asking me about Oak Leaf Grubs in our local streams here. Apparently they are quite popular for Perch fishing and are found in the settled leaves in streams and rivers. Is anyone familiar with them? I am trying to figure out what kind of insect they are and if they are terrestrial and just end up in the water when the leaves fall or if they are actually an aquatic insect. The way he was describing them it sounds like a hellgrammite but he insists that that isn't it... Thanks for any help...
