Swallowtails (Subfamily Papilioninae)

Pink-spotted Cattleheart (Parides photinus) Found in Monterry, Nuevo Leon, Mexico. Possible stray to South Texas.

Pipevine Swallowtail (Battus philenor) The caterpillars of this common butterfly are most frequently encountered in the ranch country in the northern portion of the Valley. In February of 2007 in the northern Starr County community of San Isidro, an interesting phenomena was observed of Pipevines roosting on native trees.

Polydamas Swallowtail (Battus polydamas) Uncommon but regular in the RGV. Has recently started breeding as far north as Houston and Austin!

Dark Kite-Swallowtail (Eurytides philolaus) Very rare stray. Two records in 2002 from Cameron and Hidalgo counties. Several spottings in July 2006 in Weslaco, Santa Ana NWR, and western Hidalgo County.

Guatemalan Kite-Swallowtail (Eurytides epidaus) Occurs as far north as southern Tamaulipas, Mexico

Black Swallowtail (Papilio polyxenes asterius form pseudoamericus)

Thoas Swallowtail (Papilio thoas) According to the USGS website, this species has been recorded from across the RGV and has strayed as far north as Kansas and Colorado. There are only a few representatives in the Kendall Collection, none of which are from Texas. There is one specimen locally collected in the Dallas Museum of Natural History collected in 1942.

Giant Swallowtail (Papilio cresphontes) Common throughout Texas.

Ornythion Swallowtail (Papilio ornythion) This usually rare butterfly is occasionally seen in small numbers emigrating northward in the western reaches of the Valley.

Spicebush Swallowtail (Papilio troilus) Flies in east and central Texas.

Palamedes Swallowtail (Papilio palamedes) This species is present both to the north and south of the Rio Grande. It would only be recorded in southmost Texas as a stray as its caterpillar food plant, primarily Redbay (Persea borbonia), doesn't grow here. NABA reports that there are some old Valley records. This butterfly has been recorded in nearby Kennedy County and the Picachos Mountains.

Magnificent Swallowtail (Papilio garamas abderus) One US record from Brownsville, Cameron Co. This species can be quite common in Monterrey.

Pink-spotted Swallowtail (Papilio rogeri pharnaces) - Rare stray. Less than five U.S. records, all in Hidalgo Co.

Black Hairstreak (Ocaria ocrisia) One November 1968 record from Santa Ana NWR, Hidalgo Co.

Silver-banded Hairstreak (Chlorostrymon simaethis) Uncommon along Rio Grande. Strays to the north. Look for this species in open areas where Ballonvine, its caterpillar food plant grows. It is frequently passed over due to its smallness, green coloration and sedentary habits. Upon discovery, one will marvel at its bright green coloration and prominent silver stripe. Best searched for around Cattail and Pintail Lakes on Santa Ana NWR.

Silver-banded Hairstreak x Clytie Ministreak Cross-breeding pair

Common Brangas (Brangas neora) Present in southern Tamaulipas.

Oak Hairstreak ( Satyrium favonius) Rare.

Metalmarks (Family Riodinidae)

Calephelis Metalmarks of Southwest Texas by Nick Grishin. (This is a rather large file.)

Fatal Metalmark (Calephelis nemesis) Common in South Texas, often in garden situations. Range in US along southwestern border.

Rounded Metalmark (Calephelis nilus) Common in South Texas, often in garden situations. Only US records are from south and central Texas.

Rawson's Metalmark (Calephelis rawsoni) Very few verified records along the Rio Grande, common on the Edward's Plateau to the west of Austin.

Metalmark (Calephelis sp.) South of the Rio there are even more species of Calephelis Metalmarks that are presently not possible to sight ID. 

Red-bordered Metalmark (Caria ino) Frequents gardens along the Rio Grande. Only US records from south Texas.

Square-spotted Yellowmark (Baeotis zonata) Recorded in southern Tamaulipas.

Blue Metalmark (Lasaia sula) Not recorded north of the Rio Grande Valley. Most common in Cameron County. It's most dependable at the Sabal Palm Grove. Other good locations are Laguna Atascosa NWR and Los Ebanos Preserve. This species occasionally is locally abundant. Over 300 were reported at Laguna Atascosa in November 2003.

Black-spotted Bluemark (Lasaia agesilas) No U.S. records.

Gray Bluemark (Lasaia maria) No U.S. records. 

Red-bordered Pixie (immature) (Melanis pixe) Not recorded north of the Rio Grande Valley. This magical species is sometimes difficult to find. Colonies of this butterfly seem to be ephemeral even though its caterpillar food plant, the Guamuchil (Pithecellobium dulce, legume family ), is a fast growing tree that itself forms colonies. Pixie hosting Guamuchils are known from Raymondville, Port Isabel (Adams & Tarnava, Manautou & Monroe), Weslaco (Oklahoma & 6th), McAllen (6th & Orange), Edinburg (University & Hwy 281) and in Mission. Pixies seem to prefer to fly in overcast, even drizzly weather. The lesson here is that even in normally poor butterflying weather, good things can show up in the Valley! Thorn Bugs are also sometimes found on the Guamuchils. 

Curve-winged Metalmark (Emesis emesia) This beautiful butterfly is becoming more common in the Rio Grande Valley. Only US records from Hidalgo and Cameron Counties. Most records between October and February. Host plant is  Mexican Caesalpinia (Caesalpinia mexicana).

Falcate Metalmark (Emesis tenedia) First US record from Ann Swengel's photograph shot at Santa Margarita Ranch, Starr County on October 8, 1987.

Richard Boscoe reared this species on Clematis drummondii.

Walker's Metalmark (Apodemia walkeri) Rare stray to southmost Texas. Only US records from Cameron and Hidalgo Counties

Carousing Jewelmark (Anteros carausius) Can be regular in northern Nuevo Leon, but has not been recorded from the US. Hard to believe that it’s even a Metalmark!!

Mexican Mottlemark  (Calydna sinuata) Present in northeastern Mexico, no U.S. records.

Sword-tailed Beautymark (Rhetus arcius) This species is a particularly good example of how bizarre tropical Metalmarks can be!! There are no US records for this species, though it occurs 250 miles south of the Rio Grande.

Giant Metalmark (Behemothia godmanii) This behemoth and rare species was recently spotted at Gomez-Farias (El Cielo). This is yet another example of a possible US record which occurs only a few hundred miles south of the Rio Grande.

The Forest Trail at the Palm Grove is also a good site for this species. Zebras are commonly found in openings along wooded trails. They form communal roosts at night. 2004 was a good year for this species, see county record map for 2004.

Tiger Heliconian (Heliconius ismenius) Similar to the Isabella's Heliconian but the Tiger has not yet been recorded in the U.S.

Erato Heliconian (Heliconius erato) A rare stray to the RGV. Only officially recorded from Hidalgo Co. in the US.

White-rayed Patch (Chlosyne ehrenbergii) There is one specimen of this species from "Texas" in the British Museum with no further data. The caterpillar food plant is Rio Grande butterflybush - Buddleja sessiliflora. The White-rayed Patch is endemic to Mexico but not common in Northeastern Mexico. 

Rosita Patch (Chlosyne rosita) Stray to the Rio Grande. One stray to the Lubbock area!

Red-spotted Patch (Chlosyne marina) New County Record found at Bentsen RGV WBC on 11/09/06. Rare stray to south Texas. Some 25 specimens were either collected or observed in various Starr Co. locations in October of 1973, 1974 and 1976. Two specimens from Starr Co. were deposited in the British Museum where the identifications were confirmed. Chlosyne melitaeoides was lumped under C. marina by Scott (1986) though he didn't give a justification.

Elf (Microtia elva) Five or fewer Cameron County records. Not recorded elsewhere in Texas.

Tiny Checkerspot (Dymasia dymas) Another recent find at Loma Alta northeast of Brownsville.

Elada Checkerspot (Texola elada) Jaguarundi Trail at Santa Ana NWR is one of the most dependable locations for finding this species. Also search the Valley Nature Center in Weslaco.

Texan Crescent (Phyciodes texana) Common throughout South Texas. Often along forested trails.

Pale-banded Crescent (Phyciodes tulcis) Though often absent, this species is sometimes encountered in numbers. Twelve were recorded on the 4th of July 2000 count at the old headquarters area of Santa Ana NWR.

Chestnut Crescent (Phyciodes argentea) First US Record from 1.6 mi south of Penitas on November 14, 1993. There's an earlier literature record from Relampago, Hidalgo Co. on March 19, 1970. The males are distinctive, but the females resemble the Texas Crescent.

Vesta Crescent (Phyciodes vesta) Best sought at the Valley Nature Center in Weslaco or along the Jaguarundi Trail at Santa Ana NWR.

Phaon Crescent (Phyciodes phaon) Fairly common in gardens particularly at the Valley Nature Center.

Pearl Crescent (Phyciodes tharos) Fairly common in gardens particularly at the Valley Nature Center.

Question Mark (Polygonia interrogationis) Uncommon. Likes woodlands and will come to bait. Look for silvery comma and adjacent dot which interestingly does from a "question mark" on hindwing underside (wings closed position)s.

Black-bordered Tegosa (Tegosa anieta) This species can be quite common in southern Tamaulipas, Mexico. 

Square-tipped Crescent (Eresia phillyra) Present in northern Nuevo Leon, no U.S. records.

American Lady (Vanessa virginiensis) Widespread and common year-round. Very similar to Painted Lady.

Painted Lady (Vanessa cardui) Widespread and common year-round especially in the Fall. Very similar to American Lady. This is the most widespread butterfly in the world.

West Coast Lady (Vanessa annabella) This western species appears to be expanding its range eastward. Dale Clark and John and Gloria Tveten recently found individuals of this species in Hidalgo and Cameron Counties. Now Barbara Ribble photographed this one in western Medina Co. immediately west of Bexar Co. (San Antonio).

Red Admiral (Phyciodes tharos) Common and widespread. Very reliable in the Fall and will readily come to bait.

Common Buckeye (Junonia coenia) Photo of larvae shown.

Tropical Buckeye (Junonia genoveva) Mostly found along the coast.

White Peacock (Anartia jatrophae) Frequents gardens. Freshly emerged White Peacocks are a beauty to behold! Wide spread in the Rio Grande Valley.

Banded Peacock (Anartia fatima) Occasionally found in small numbers along the Rio Grande in Starr County. Very rare stray northward.

Malachite (Siproeta stelenes) This gorgeous large green butterfly prefers the moist woodlands along the Rio Grande, but wanders widely and thus singletons are apt to show up anywhere. Often found feeding on fermenting fruit, even Anacua berries may attract this butterfly. One recent October canoe trip along the southern border of Santa Ana produced 23 Malachites!

Rusty-tipped Page (Siproeta epaphus) This photograph is a New Texas Record, Second U.S. Record. It was shot south of Alamo, Hidalgo Co., TX on November 27, 2001 by Judy Quintanilla.

Admirals and Relatives (Subfamily Limenitidinae)


Red-spotted Purple (Limenitis arthemis arizonensis) This species was validated for our area by a single recent record from Starr Co. The nearest populations of Red-spotted Purples normally occur on the Edwards Plateau, west Texas and northern Mexico.

California Sister (Adelpha bredowii) While this oak feeding species is common both to the north and south of the RGV, this photo represents possibly the first RGV record. 

Band-celled Sister (Adelpha fessonia) Occasional. One U.S. record north of the RGV at Chock Canyon State Park near Three Rivers, TX.

Spot-celled Sister (Adelpha basiloides) U.S. records from Starr, Hidalgo and Uvalde (!) Counties...

Orange Banner (Temenis laothoe) New U.S. Record! November 28, 2004 at Penitas, Hidalgo Co. 

Mexican Bluewing (Myscelia ethusa) This species should be looked for in any forested area across the Valley. Trails that are sufficiently dense often yield half dozen sightings of this beauty. Unfortunately they tend to perch just out of camera range, with their wings closed!!!

Dingy Purplewing (Eunica monima) Rare. Some times found in small numbers when encountered. Numerous Texas records in 2002.

Florida Purplewing (Eunica tatila) Stray to the Rio Grande. Less common than the preceding species. Perhaps only two RGV records since 1996, both in Hidalgo Co. One Odessa record!

Blue-eyed Sailor (Dynamine dyonis) Apparent population at Santa Ana NWR in October 2003. Several individuals were seen on Owl Trail in the southern portion of the refuge. One individual was seen at the refuge on Jaguarundi Trail on a Christmas Bird Count in the late 1990's. All U.S. records are from Texas. There are some 19 county records for this species between the Red River and the Rio Grande. This is a good example of an occasional species, "probably not present every year, but occasionally present in moderate numbers." 

Four-spotted Sailor (Dynamine postverta) New U.S. Record! Male and female found in Mission December 2005.

Anna's Eighty-eight (Diaethria anna) There have been mostly sight records of probably several species of Diaethria from West Texas to South Texas and even one in Central Texas.  

Navy Eighty-eight (Diaethria astala) This is probably the most likely species of Diaethria to occur in South Texas.

Common Mestra (Mestra amymone) Fresh individuals really stand out with their dark forewing borders and orange hindwing patches. This species is found in a wide variety of habitats including woodlands. This species has strayed as far north as South Dakota!
