Here are two dragonflies on the same ragweed stalk. The top one is a halloween pennant, and the lower one an immature male roseate skimmer. I wish they had been close together so I could upload a bigger image, but I think this is about as close as they get--I suspect the skimmer had intentions of eating the pennant, which in fact flew away right after I took the shot.
