It's No Secret; I Love These Guys!

 For a couple of weeks now I've been watching the Oak Treehoppers in trees along my driveway and in the nearby forest.  But recently they appeared in a California Black Oak on campus right next to a busy paved walkway.  I hope to show them to my class on Wednesday, but there's no guarantee they'll still be there.  The fourth photo from the top is a particularly good one of the olive drab adult. 

This is one critter that never tempts me to take up video.  They never seem to move!
