Texas Wasp Moth (Horama panthalon)

…a species of Tiger Moth (Actiini) that is native to the Americas, ranging from Arizona to Florida in North America south to South America. Like other tiger moths H. panthalon flies during the day and usually feeds on the nectar of Eupatorium spp. The bright coloration of Horama panthalon is actually a form of Batesian mimicry where H. panthalon mimics wasps of the genus Polistes for protection from predators.

…a beautifully marked species of Tiger Moth (Arctiini) that is known to occur on the island of Borneo. Spilosoma ericsoni is sexually dimorphic with males having red forewings and immaculate hindwings. The forewings of the females are less red and have large black spots in the first two spaces from the dorsum, their hindwings also have a yellow fringe.

Confused Haploa Moth (Haploa confusa)

…a species of tiger moth (Arctiinae) that is native to North America, ranging from Manitoba to Maine south to Pennsylvania and the “Great Lake States”. Adult Haploa confusa typically fly during the spring and are usually seen on a wide variety of different plants. H. confusa larvae, however, typically feed on Hound’s Tongue (Cynoglossum officinale)

Adults are most often reported from March to November. Florida and Texas have adults reported every month of the year. (10), (9)
Larvae feed on many herbaceous plants, including alfalfa, asparagus, bean, beet, cabbage, clover, corn, cotton, cucumber, grape, grass, jimsonweed, morning glory, onion, pea, peach, peanut, pokeweed, sweet potato, tobacco, tomato, turnip, wheat, watermelon, and wild onion.

Life Cycle
Overwinters as pupae in soil. Adult emergence begins in early April and continues into May. Egg masses placed on foliage, trees, or buildings. Eggs hatch in about 6 days, and larvae feed for 3 weeks. Sixth instar larvae burrow into soil to pupate. Moths emerge in two weeks. Entire life cycle takes 4-6 weeks. Three to four generations per year.


Army Cutworm (Euxoa auxiliaris)

Also known as a “Miller Moth” when it is an adult the Army Cutworm is a species of Dart Moth (Noctuinae) that occurs throughout most of western and central North America south to Mexico. Army cutworms are seasonal migrants with populations moving to higher elevations in summer and returning to lower elevations in the fall to oviposit. Army cutworm larvae have a fairly wide diet which includes plants from 16 different families, they seemingly prefer cereal grasses though. Adults will take nectar and are very accomplished fliers with individuals recorded flying for 23 hours and 133 miles!!
