These are as fresh as the Monarchs in Austin this spring.

This I would refer to as gloss-fresh. It does not last long. None of this
spring's Austin Monarchs have been this fresh.

Yes that is it - good picture.

This may happen on the Gulf Coast (in Mexico) but I have not been there
recently to check their reproductive status. I suspect they are active,
because the ones that lingered in Texas (Central and Gulf Coast) this year
through January were laying eggs on *A. curassavica*.
