And for the themed:
What about FlorAzul (blue flower in Galician) or Tilkka (splash in Finnish) for her?(her blue petals look like flower petals or splashes of water)

What about Prunae(coal in Latin) for him?

And possibly Ardere(glow in Latin) for her?

Will come back with more, soon hopefully

What about: Blume(German for flower) or Rosa (pink in German) for her:

Hm... I really like a lot of the names you suggested, but the only two that I really think are perfect are Narrasti and Tilkka. So I named my two Ryori ladies those.

The other names were close, but not quite what I want.

What about CobaltWing or MetalClaw or BluingSteel (a processs to protect steel from rust)for your lighira?

Edit: Updated with images of the teen Monarch Nixies.

NAMED!
This Chocolate Swirl boy takes his Theme literally, and needs a name--

"Chocolate Therapy"--inspired by Kittenroar's suggestion.
My female CS Sylvorpa is named "Mississippi Mudpuppy," a portmanteau (look it up!) of the chocolate dessert Mississippi Mud and the real-world amphibian called a mudpuppy. A similar name for this male would be nice, but I'll consider absolutely any name. The important thing is that it suits him.


And I have Hatchlings and teenagers to name!

NAMED!

A genuine, for-real Cool Night Sylvorpa, the only one I own. No name too crazy to consider.
"Noctilucent Cloud," inspired by Songbreeze's suggestion of "Sunset"


NAMED!

These two Monarch Zolnixies are unrelated, which is awesome. Clearly they are meant for each other. (Much appreciation to Mikazukichan for this pair!)
They are now "Tramontane" and "Kai Ken."


NAMED! "Betise de Cambrai" Thanx to Sevenblazes!

This teen Peppermint Twist needs a name. My other PT Nephini is named "Air Bon," after the peppermint candy.


NAMED!

My birthday present from CuddlyFierc needs a name. (Yes, I already thought of "My Precious," but the Precious came to a bad end.)
She is now "Pastille"


NAMED!

Finally, this Mischievous Puffadore needs a mischievous name.
"Sly Rascal"

Some name suggestions for you. :)

This stallion has Tiger Stripes, and tigers are from Asia, where they also make a number of different kinds of nut brittle, including brittle from peanuts and other groundnuts. In Bangaladesh, groundnut brittle candy is called kotkoti. That would be a good name for him.

"Kotkoti"

I don't suggest using the name for the same candy in India, even though they have more tigers there, because the name is chikki, and I already have a Kelpari by that name.

How about naming him Machwa, it's Swahili for dusk, or sunset.

Wow, lots of names to choose from.

I really like Laramie and Zilthai, but I went with Laramie.
