I believe this is a katydid nymph because of the long antennae. It was tiny--about 4-5mm. Any help with an ID confirmation would be great.

The family Tettigoniidae, known in American English as katydids and in British English as bush-crickets, contains more than 6,400 species. It is part of the suborder Ensifera and the only family in the superfamily Tettigonioidea. They are also known as long-horned grasshoppers, although they are more closely related to crickets than to grasshoppers. Wikipedia
