Corn worms and sap beetle
We plant corn every year in our garden in Fleming CO. The last 2 years these tiny black beetles just devour the silk on the ear of corn, then between the beetle and the worm, they will eat a whole ear of corn! I was told I need to grow a certain variety of corn in this area to eliminate this problem. Is this true? If so, what type of corn is the hardest and best to grow in the Fleming area? Also, would spraying the corn help?

The worm you are seeing is likely corn ear worm which is a common pest on corn in the state. More information including information on control can be found here:
The back beetle could be several things from a flea beetle (http://www.ext.colostate.edu/pubs/insect/05592.html) to a type of lady beetle. Would it be possible to send a picture?
