Mexican Crescent at National Butterfly Center, 11/7/24

A few days ago visiting butterfly watchers found an unusual looking crescent while wandering around the Roma birding overlook.  Valley butterfly guru Mike Rickard later identified it as a Mexican Crescent.  It's one of those typical spotted checkery Phyciodes species that can be so confusing.  I've never seen one.  All I know is it looks like a Phaon Crescent but the final pale spot on the subterminal row on the forewing lacks the black dot characteristic of Phaon and Pearl Crescents.

Well today I was taking it easy after putting in a hard day yesterday at the National Butterfly Center.  I was editing photos and getting caught up with this blog and iNaturalist stuff when the GroupMe dinged.  Bob Yukich had just found another Mexican Cresent at the butterfly center.  I raced right over and there was the gang from yesterday and a few more admiring Bob's find right in front of the visitors center.  All I had to do was get out of the jeep and walk a few feet.  I like it when they're easy!





Here a Phaon Crescent is excited by pheromones emitted by the female Mexican Crescent.



It was a lifer for everyone except maybe Mike Rickard who has fifty yeaars of butterfly experience in the RGV.  I was just happy to really see one and observe the field marks.  Strong southerly wind ahead of a weak cold front is expected tomorrow so maybe more good stuff is on the way.
