Great Day at the National Butterfly Center, 6/25/26

It's been normally hot and breezy for this time of year in the Lower Rio Grande Valley.  But a Gold-spotted Aguna and a Ruby-spotted Swallowtail were reported at the Nationaal butterfly Center so I thought I had better get myself over there before everything fries.

It was hot and nasty when I stepped out of the apartment but when I got over to the NBC and started sweating a bit with a nice breeze it was fine.  My first butterfly was a Clytie Ministreak.  There were lots of them.

I worked the front garden a while and saw only common stuff.  Then all of a sudden, at about 11am, the hairstreaks started to pop.  First there was a White Scrub-Hairstreak.  New for the month!

And then a Ruddy/Muted.  This one never opened it's wings although the probability it's a Ruddy is about 99%.

But this one flashed orange when it flew so it's a male Ruddy Hairstreak.

Then the usual Dusky-blue Groundstreaks and Mallow Scrub-hairstreaks.  And then the common for this summer but usually rare Clench's Greenstreak.

Peggy had joined me by this time and two more Clench's showed up.  We totaled six of them for the morning with six species of hairstreaks in this one little fiddlewood.  Nearby I found the first of three Marius Hairstreaks,

A bit later I showed Peggy a blooming crucillo and explained to her it was the host plant for Band-celled Sister.  A minute later I was shocked when she called one out.  I got my camera out and shot a photo.  The band was wrong.  Not a Band-celled Sister.  Then I realized the under wings were all wrong and it was not even a sister.  It was a female Silver Emperor.  Another new one for the month!  We  had so many last winter I was expecting we would see some this summer.  It was a pretty easy to make mistake on the blooming Randia rhagocarpa.

It was a really good morning with eight species of hairstreaks and a Silver Emperor.  I drove to the south garden, ate my lunch and made another try for a ten hairstreak day.  I failed on my last try a few weeks ago.  The Curve-winged Metalmarks are still plentiful.

And plenty of Mexican Bluewings.  I caught this one in the act laying an egg on the Vasey's Adelia.

Then I noticed the Brush Holly patch was blooming.  This is our spot for daggerwings during summer.  Today it was covered in American Snouts but I did mange to pull out another Silver emperor.

Then I saw a Tachytes species of wasp just sitting there on a leaf waiting for a photo.  So I took one.  Woops it's not a wasp at all but a damn Dipteran!  The antennae say fly as to the tiny green vestigal wings.  I haven't entered it into iNaturalist yet but I'm guessing this is a Tachytes mimic.  Look at those freaky eyes!

It was getting warm.  I walked over to the blooming Mexican Orchid and found it loaded with Lyside and Large Orange Sulphurs and Great American Whites.  But one of them had spots.  First Giant White for the month.

There were several Western Giant Swallowtails.

And then the one I was looking for, a fresh Ornythion Swallowtail.

So a pretty fantastic day with four new species for the Big Board briging the June total to a record 92 species.  53 species today is pretty incredible for this time of year.

Starred Skipper at National Butterfly Center, 1/1/26

Happy New Year!  Well Dennis Vollmar did it again.  Because of our phenomenal butterfly fall in the Rio Grande Valley of south Texas, Dennis flew up from Florida a second time this season to look for vagrant leps.  Back on 12/28/21 I was present at the park when Dennis found the first US record for Tanned Blue-Skipper.  This morning he found another mega rare butterfly, Starred Skipper.  Back in October Terry Mortier found a worn Starred Skipper but no one else saw it.  However this fresh specimen put on a show for all who were in the park today.  It is a species I have long wanted to see and my 233rd for the RGV.

A bit earlier I thought the New Years bug of the day would be this Angled Leafwing.

This season bright male Pavon Emperors are not a big deal.

The same with Silver Emperors.

Young birder phenoms Ryan Rodriguez and Nolan Walker found a Guatemalan Cracker.

The Malachite a few inches away drew little fanfare.

The hairstreak show continued today with nine speces.  The rare Black Hairstreak returned and was the second best butterfly of the day.

Other hairstreaks included Marius and Silver-banded Hairstreaks and the charming Clytie Ministreak.

I forgot the beat up White Scrub-hairstreak.

This big Scolia guttata is a first for the RGV according to iNaturalist.

Warm weather continues.  Full steam ahead!

National Butterfly Center, 11/24/25

I was not going to go to the National Butterfly Center.  I wanted a rest day and had stuff to do.  So while the butterfliers were running around seeing stuff, I was accomplishing things.  I even got in a pretty good workout.  I was going to thaw out some chicken for a stir fry, but the damn butterfly watchers kept reporting stuff.  First the usual Malachites and Red Rims.  Then a Ruddy Hairstreak.  Then a White Scrub-Hairstreak.  Blue-eyed Sailor was the straw that broke the camel's back.  I've seen a few of those but if Blue-eyed Sailors are showing up, what else could be in the offing?  So I raced over to the National Butterfly Center and found the crowd focused on the Blue-eyed Sailor.  That was easy.

The first Julia I've seen in months took our attention from the sailor.

The Ruddy Hairstreak failed to show any orange on the topside that would designate it as a male Ruddy.  So it has to fall ito the Ruddy/Muted category.  Glassberg says it is not known how to ID Muted Hairstreak in the field.  This is most likely a female Ruddy Hairstreak.

Then we heard a distant call of "Pale-spotted Leafwing."  We started running, some of us faster than others.  I like the exotic shape of the fore wing.  It didn't stay long.

Red Rims are being seen daily.

Silver-banded Hairstreaks have become common.

And so many Clytie Ministreaks.

Then Terry found another White-scrub Hairstreak.

I later heard that the Indiana Gang had seen 100 butterfly species on the day.  Yikes.  This is turning into one of the best fall butterfly seasons ever in the RGV.  Good stuff is coming.

A New Tiger Beetle for Hidalgo County, 11/6/25

I finally got caught up with my photos and iNaturalist stuff for the Texas Butterfly Festival so it was time to run over to the National Butterfly Center and take advantage of the beaurtiful weather and look for rare butterflies.  I really wanted to check that big crucita patch on the south 70 acres.  As I drove back I checked a few crucita and found nothing interesting.  Then as a I approached the little pond I noticed it was very low with mudflats around it.  Ode guru Ben Schwartz had found some good dragonflies here a few weeks ago.  Maybe I could find something.  Maybe even a tiger beetle.  I don't have any for the park.

I walked a round the dry mud and trampled sedge.  The local deer and javelina have been having fun here.  Dragonflies were all common stuff.  The huge Common Green Darners were mating down in the sedge and their wings beating against the blades of grass startled me at first.  Rattlesnakes?

Then a black tiger beetle on the damp mud.  I expected the common S-banded Tiger Beetle.  Wrong!  I got lots of photos of this first iNaturalist record of Punctured Tiger Beetle.  It's one of the most common tiger beetle species across the eastern three fourths of the USA.  There are single iNat records from Starr and Cameron Counties.  But the field guide shows it occuring across all of Texas.  I was hoping to find one some day.

The rest of the afternoon was just a replay of the last few days.  Good stuff but the same stuff.  Here's the Malachite.

Up front the fire bush (Hamelia patens) was still hopping with hairstreaks.  The Yojoa and White Scrub-Hairstreaks were still popular with the visiting butterfly watchers.

And the Marius Hairstreak.

And a coy little Dusky-blue Groundstreak.

I checked the crucita in the mesquite woodland hoping for Terry's Starred Skipper.  This sharp Guava Skipper was not adequate consolation.

Another good day!  Tomorrow I'm thinking about a run up to Rockport for a couple of lifers.  We'll see how I feel when I wake up.
