Common Sawfly (two photos)
Genus Tenthredo

This is about the strangest face I've seen on a sawfly or wasp but I haven't
seen all that many yet. Aren't the yellow markings neat in contrast with
 the orange and black? This one was gawking at me
 at Brighton, Utah.  Carol Davis, 7-13-2010

Most of the Common Sawfly larvae feed on leaves but some are borers or
 leaf miners.
Eric Eaton has a great article on this genus of sawfly here.
