Telea Hairstreak at Falcon, 9-16-25

I had not been to Falcon State Park in a few weeks so I thought I would run up and check the bird and bug situation.  The lake levels were still very low, about the same as my last visit.  There were just a few Least Sandpipers and Spotted Sandpipers and tiger beetles were just the regular Ocellated and S-banded.  Here's a Western Giant Swallowtail sucking out minerals from the mud.


So I checked out the butterfly garden.  The park staff has done a pretty good job of keeping a little water on the garden and they have had a bit of rain so the garden was actually looking good.  As has been the case, there wee not a lot of butterflies present.  But I did find a good one as I was watching bees in the blooming kidneywood.  A small hairstreak over my head, back lit agaist a bright sky, turned out to be a rare Telea Hairstreak.  This is the fifth I've ever seen and my first for Starr County.  And she seems to be oviposting.




Bee-wise there were a couple of good ones.  One clump of blooming kidneywood was hosting both of our Valley large Oxaeine Andrenid bee species.  This is the fourth time this summer I have found Mesoxaea texana.  Maybe it's not as rare as they say.



And there were at least a half dozen Protoxaea gloriosa,  It was a great opportunity to compare the two species.




It's shaping up to be a good fall butterfly season in the RGV.
