DISTRIBUTON:

The Oslar's oakworm moth, Anisota oslari (wingspan 50-88 mm, females larger than males), flies in southeastern Arizona, New Mexico, southwestern Colorado and western Texas and down into Mexico.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Anisota oslari adults fly in July and August during the rainy season.

Oslari larvae feed upon oaks in the canyons and hillsides within their mountainous range.

ECLOSION, SCENTING AND MATING:

Females call during sunny spells from 8:30-11:30 am, and the pair usually remain coupled until early evening when the females begin their ovapositing flights.

EGGS, LARVAE, COCOONS, AND PUPAE:

Larvae are gregarious but divide into smaller clusters as they progress. They leave the tougher midvein of the foliage intact. In the final instar they are solitary feeders and leave the host to pupate in shallow chambers. Photo by Leroy Simon. Pupation is under the soil.

Larvae do well in sleeves or on cut food. Pupae should be stored above freezing temperatures.
