Chris, I wish we could see some pictures of these
fresh, little faded, unscratched monarchs you have been seeing in
Austin, TX so we could compare them with the pictures we have
of the condition of the monarchs just before they left the
overwintering reserves in Mexico.
For example, here is a picture of the typical condition of the
monarchs at the Chincua reserve on Feb. 25:

are moderately faded, but not tattered.
For comparison, here is a newly emerged monarch:

So Chris, have the monarchs you have been seeing in Austin this month
been nearly as fresh looking as a newly emerged monarch? Or have
they been more like the pictures of the monarchs at Chincua on Feb. 25?

at Chincua reserve Feb. 25 with the more rounded fore wings and white

A. currassavica was common below 7,000 feet in the region of
the overwintering sites in Mexico, and it was easy to find
monarch caterpillars on the plants. This is a picture of
some currassavica along highway 15 in Tuxpan, Michoacan
elevation 5,600 feet (which lies inbetween and slightly south of the
Cerro San Andres and Chivati-Huacal overwintering sites)
I managed to smuggle my butterfly net into Mexico and caught (then
released) 3 reproductive monarchs flying in the vicinity of some milkweed
at Tuxpan, Michoacan. All three monarchs had the salmon colored
