Hi there,
When I read this thread, the first thought that came to mind is that some fairies can appear as insects like dragonflies. My other thought was to mention a book I read by Ted Andrews titled Enchantment of the Faerie Realm.
He goes through his experiences with fairies and provides exercises that are designed to increase your awareness of the fairy realm. This includes elementals, nature spirits, etc.
When I first became aware of the elementals and had some contact with the fire elementals, I learned from them that they prefer to be called pyromen. It could be a simple matter of using a preferred 'name' that can make the difference of connecting with them or not.
As for the water elementals, instead of calling them undines, try using merfolk for a better connection.
Anyway, I found the book useful for exploring the fairy realm. Have fun with your own explorations if that is what you choose to do.
