Description: The elm sawfly is not considered a problem in forest situations, but can be a defoliator of shade and ornamental elm and willow trees. The elm sawfly is the largest North American sawfly with larvae reaching a length of almost two inches. The larvae pictured here were found feeding on an American elm tree in Bastrop, Texas (near Austin, TX) on May 2, 2002. Larvae are a yellowish-white color and possess a black dorsal stripe. While feeding, the larvae usually coil their posterior around a leaf or twig. At rest the larvae roll into a characteristic tight coil. The larvae spin tough, papery cocoons in the litter or just below the surface of the soil.
