Features
The moths have a forewing length of 50-62 millimeters. The top of the forewings is dark gray with brown shades. A series of narrow bars running from the wing tip to the Diskalfleck. A broad, dark brown spot extending from the center of the outer edge to the base of the wing. Between the lines and the spot of the forewing of the cell to the outer edge is gray. The upper side of the hind wings is black with brown gray border and two white napkins. On the thorax there is a pair of dark brown, black margined longitudinal bands. The species is often confused with Lintneria separatus. However, the similar species has a pair of small orange spots on the collar of the thorax, which lie directly behind the sensor bases and the Lintneria missing istar. The white portion of the front wing and the dark brown stain on the fore wings are somewhat variable.
The caterpillars are black in color, which make it appear spotted by very many, small, gräulichweißen secondary bristles is covered and so the caterpillars. The bristles are sometimes grouped together so that form oblique lateral stripes. The caterpillars are well camouflaged with their coloring to the woody stems of food plants. As with the closely related species, the caterpillars have a fleshy protuberance at the beginning of the second segment of the thorax, which is replaced by a hump at the last stage. On the back of the hump is located on the second and third thoracic segment a large black spot, which is edged with white and light brown. On the first thoracic segment, there is another, smaller black spot, which is edged with white.
The pupa is dark brown and has a smooth, fairly shiny surface. The free proboscis sheath is quite long and reaches about 40 % of the length of the wings. She writhes in an arc away from the body and touches it again with the tip. The short cremaster is broad and ends in a slight double peak.
Occurrence
The range of the species extends from the southern U.S. to Central America. In the United States Lintneria istar in Texas, New Mexico and Arizona is widespread, with species most commonly occurs on the Mexican border. From New Mexico, it is only detected by a detection of Sandoval County in the northwest. In the south, spreading across Mexico reaches at least to Guatemala.
The animals inhabit canyons and slopes in the mountains. They are found at altitudes of about 1500 to 2500 meters.
Way of life
The moths are attracted to light sources. They are detected in flower visiting on Salvia greggii and Salvia lemmonii. The moths emerge in captivity during dusk.
Flight times and caterpillars
The moths fly in one generation in July and August during the summer rains.
Food of the caterpillars
The caterpillars feed on Salvia Salvia greggii lemmonii and sophisticated.
Development
The females lay their greenish eggs singly on both sides of the leaves of the caterpillar food plants. The eggs are very often attacked by parasitoids. The caterpillars are nocturnal and hide during the day in plant debris on the floor near the food plants. They are daytime only very difficult to detect. Pupation takes place in a chamber several inches deep in the ground.
