For this Nephini, how about Rosa or Rosea?
And the Nephini that comes after it (number 6) could be named Peach Tree or Peach Grove, as the pattern on his wings reminds me of peaches.

Oh I've got to join this. Just give me a pet and I'll give you a great name for it! ;)

Page back through the posts, Atomic! There are lots of pets still needing names.

Everybody else, if possible go back and edit your original "this pet needs a name" posts to show who has been named, by either striking through the pet's information or writing "named" or something like that by the pet. Or post "Named" and then put the name you picked, so people get an idea of the kinds of names you're looking for. Then other players can easily see that the pet is no longer "in play," and you are not trying to re-name it.

And remember that Castielle does still have a Nephini to re-name. A re-naming is worth ten points if the owner accepts your suggested name!

What about icicle for her?
And maybe princess or pastel(light colors) or Hydrangea for her?
Hydrangeas:

Sorry I can't make smaller, I don't know how to with links other than links to images of sylesti.
Will come back with more!

Your lighira could be named Chaofeng (Pronounced like show+fong) which, in Chinese Mythology, are one of the nine offspring of dragons. They also resemble lions. I got the idea when I saw your Lighira had Eastern Dragon Horns.

You could name the Poinsettia Faelora Bouquet, as it is flower themed.
The Cherry Cheesecake Faelora could be named Washington, after the old story about George Washington chopping down a cherry tree.
The Werebear Morkko could be named could be named Luna, for the werebear aspect, as were-anythings are usually associated with the moon.

I like that name, I'm gonna use it!! :D

The Nephini has been named Hydrangea! Thank you, Wildcat2704. :D

I'm using Sevenblazes' suggestions of Solar for the Draeyl and Evelyn for the Sylvorpa!

And of course editing my original post to remove those who have been named~

I'm glad you liked my name! I've got a few more for you!
For the Vulnyx, you could use the name Stardust, which not only fits by itself, but it's also the name of a NASA spaceship that brought back gemstones from space! It fits, as your Vulnyx has both Galaxy Stripes and Jeweled Wings!
You could call the Lighira with flame wings Blackburn, which is the name of a Volcano in America (Well, Alaska, but it still counts!) I chose it because his mother is a Patriotic offspring, and his father is also named after a volcano. Paired with his color scheme and flame wings, I think this name works well!
And for the second Lighira, you could use Vierer (Pronounced Fee+Her) which is German for both Four and Fearsome. I chose it because of the Quad Horns mutation, and lions are definitely fearsome right?
