The common Tiger Dragonfly has a Tigerfern leaf in its collection bottle, so I'd hazard a guess that it likes Tigerferns. \:\)

The common Shiny Blue Beetle has a different leaf in its bottle, but I can't be sure what particular variety of foliage it is. It looks similar to that in the rare Shiny Flower Beetle's bottle. Those with better eyesight may be able to identify it.
