The larvae of this uncommon moth feeds on Phyllanthus sp. in Florida, family Euphorbiaceae. Phyllanthus spp. are common in Texas. The adults probably mimic Red-bordered Pixies.

Family Adelidae

Adela Moth (Adela sp.) A small moth with quite long antennae. 

Family Arctiidae

Subfamily Arctiinae

Milkweed Tiger Moth (Euchaetes egle) Common throughout eastern North America.

Ornate Utethesia (Utetheisa ornatrix) Common on S. Padre Island.  It breeds year round at the Convention Center. 

Subfamily Ctenuchinae

Scarlet-bodied Wasp Moth (Cosmosoma myrodora) Stunning moth! New Calhoun County Record recorded in Port O'Connor October 25, 2006. These moths display warning coloration, yet the caterpillars host on  non-toxic Climbing Hempweed, Mikania scandens, (family Asteraceae), a weedy vine at field margins and roadsides that can completely obscure bushes and small trees. The male moth extracts toxins called "pyrrolizidine alkaloids" from Dogfennel Eupatorium (Eupatorium capillifolium) and showers these toxins over the female prior to mating. The scarlet-bodied wasp moth is the only insect known to transfer a chemical defense in this way. For more information, see this Wake Forest University article: A gift of poison: moths and safe sex. The moth occurs along the southeastern U.S. coast from Texas to Florida, This is the fourth Texas coastal record.

Texas Wasp Moth (Horama panthalon texana) A not uncommon day-flying moth in the RGV. Ranges north to the Red River, and west to the Trans-Pecos and Southeastern Arizona.
