I have never got the first fish on corn. But lake just west of kalispell, Mont I used to use those little marshmellow's and a but we caught in the water there and got trout. Seems there was so much grass on the bottom the marshmello's floated the bait up where the troutcould get it. Those bugs we called itchy bugs. Walk along the shore and find them under rocks, lot of them around back then!
