RED HEADED PINE SAWFLY - (Neodiprion lecontei).The larvae of these sawflies have bright red heads and a yellowish-white body with six rows of black spots.  When mature, the larvae reach about one inch in length.  The adults are about half an inch long with brownish beetle-like bodies and they are winged.  Eggs, which look like rows of small tan spots, are deposited on the needles.  The larvae feed in groups and strip the needles from branch and twig ends.  It is possible for heavy infestations of the redheaded pine sawfly to defoliate and kill small pines.  Look for egg spots and larvae on needles from May through June and from August through October.  Trees growing under stressful conditions are most often attacked. At the Morris Arboretum, redheaded pine sawfly larvae colonies have been sited on pitch pine and on a young white pine. This major native pine pest prefers jack, red, shortleaf, pitch, Swiss mountain, Japanese, black and Mugo pines.  Occasionally they feed on white pine, larch, deodar cedar, and Norway spruce. If the sawfly infestations are light, the colonies of eggs or larvae can be pruned off and destroyed.  Heavy infestations on many or large trees may be sprayed with a summer horticultural oil when larvae are small.  A residual insecticide is needed if the larvae are large.
