Taken in my garden back in the summer. This little guy is getting ready to take off... Spittlebugs are the insects that create those foamy masses on plants. Inside of these are spittlebug nymphs who live in these little nymphal shelters until ready to transform into adults http://www.pbase.com/laroseforest/image/125873217). Some of the foamy shelters hold only one nymph, but sometimes you'll find several.
