	Southeast Alaska Forest Health; Hemlock Sawfly
		Hemlock sawfly is a small wasp that feeds on the foliage of western hemlock throughout Southeast Alaska.
		Sawflies are more numerous and outbreaks tend to be of longer duration south of Frederick Sound, especially along Clarence Strait, the most southern and warmest area in Southeast Alaska.
		Depletion of host foliage is likewise known to impact sawfly populations resulting in starvation and poor nutrition of actively feeding larvae.

	Mountain Ash Sawfly
		The mountain ash sawfly, Pristiphora geniculata (Hartig) is a common defoliator of mountain ash in the northeastern United States and Canada.
		The egg laying device of the female sawfly is saw-like in shape; thus the common name for this insect group.
		The young larvae of the mountain ash sawfly are greenish white with head and legs fl in color.

	HortResearch Publication - A Guide to Willow Sawfly in New Zealand
		As noted above, the sawfly was first discovered in February 1997 following heavy defoliation of tree willows, and was widely distributed in the Auckland isthmus.
		By late summer/autumn 1997 the sawfly had been found in Rotorua, and possibly Tauranga and Gisborne (these last sightings were not positively identified).
		Adult sawflies lay their eggs in willow leaves; emerging larvae feed on the leaves and then form cocoons either on the tree or in the soil under the tree.

	AllRefer.com - sawfly (Zoology: Invertebrates) - Encyclopedia
		Sawflies are named for the two sawtoothed blades of the female's ovipositor that are used for slitting leaves or stems in order to deposit the eggs.
		Both the sawfly and the closely related horntail, whose burrowing larvae are the hosts of the ichneumon fly, lack the characteristic constricted abdomen of other hymenopterans.
		Sawfly larvae resemble caterpillars; some are leaf and stem borers, many feed on the surface of foliage, and others produce galls.

	Sawfly: pictures, information, classification and more
		Female sawflies have ovipositors, or egg-laying organs, that are partially modified into sharp-toothed, sawlike instruments with which the insect incises leaves and plant stems to form a receptacle for eggs.
		The largest of the common sawflies is about 2.5 cm (about 1 in) and has a wingspread of about 5 cm (about 2 in); the larvae of this species feed on the leaves of many trees, especially of willow.
		The rose slug is classified as Cladius isomerus, the currant sawfly as Nematus ribesii, and the larch sawfly as Pristiphora erichsonii.

	Sheep Chomp and Stomp Sawfly
		Hatfield and Blodgett plan to continue their studies to determine the mechanism of sawfly control, whether there is a yield improvement in the crop after sheep have fed on the previous crop's stubble, how sheep grazing affects fall and early spring-sprouting weeds like cheat grass, and how sheep dung contributes to soil nutrients.

	Sawflies of Trees and Shrubs (Site not responding. Last check: )
		Sawflies are a group of insects related to wasps and bees.
		If sawflies are full grown, treatment is not necessary since they are finishing or have finished feeding; most damage to the plant has already taken place by this time.
		Finally, because sawflies often feed in groups, chemical applications should be directed only to the areas they are feeding on; entire tree sprays are unnecessary unless populations are wide-spread throughout the plant.

	The Larch Sawfly
		Outbreaks of the larch sawfly became apparent in Alaska in 1993 when 12,000 acres of tamarack (eastern larch) defoliation was observed in interior Alaska.
		In 1999, the larch sawfly was recorded from the Mat-Su valley and the Anchorage Bowl feeding on ornamental Siberian larch.
		The purpose of this brochure is to describe the life history and life stages of the larch sawfly and to present the homeowner with some guidelines for minimizing damage to ornamental and native larch.

	Sawfly
		Some sawfly larvae are slug-like, appearing slimy, non-segmented and translucent, greenish to fl, while others appear wax-covered in some of their developmental stages.
		Larvae of the flheaded ash sawfly, Tethida cordigera (Beauvois), and brownheaded ash sawfly, Tomostethus multicinctus (Rohwer), feed on red and white ash.
		They are called sawflies because females of most species have a saw-like structure on the tip of their abdomens used to inject eggs into plant tissue.

		Other sawfly species and moth larvae may also occur on these plants.
		The common gooseberry sawfly is the most troublesome pest of gooseberries.
		Female sawflies lay eggs on the underside of leaves low down in the centre of the bush, so the young larvae go unnoticed until they have eaten their way upwards and outwards, devouring the leaves as they go.
