Common Sawflies (Tenthredinidae) - 253 Species, Identification & Facts

Allantus basalis

Not too commonly found. Very close to A. nigritibialis , also on Rosa ; ovipositor needs to be examined to distinguish them.

Curled Rose Sawfly

Allantus cinctus

Identification: Larva is light green with white dots and an orange head with dark markings. Curls up like a snail, usually on undersides of leaves

Aneugmenus flavipes

Identification: Fairly readily identifiable by the combination of black body apart from entirely yellow legs and yellow "shoulders".

Pear Slug Sawfly

Caliroa cerasi

larvae feed on upper surface of leaves producing distinctive skeletonizing wounds ( 7 )

Scarlet Oak Sawfly

Caliroa quercuscoccinae

Identification: Larvae are slug like. Adults black with yellowish legs.

Cladius gregarius

Identification: A similar species, Trichiocampus grandis , has a number of large black spots on each side of the body (on the suprastigmal lobe), but there are no spots on the back, according to Lorenz and Kraus, 1957.

Bristly Roseslug Sawfly

Cladius pectinicornis

Identification: "Few sawflies have hairs such as this. Rather long hairs on body, prolegs on abdominal segments 2-7 and 10, and feeding on rose pretty well narrows this down to the bristly roseslug." --Dr. Smith's comments may damage raspberry and st

Woolly Butternut Sawfly

Eriocampa juglandis

Identification: larvae peculiar, covered with long threads of wax

Woolly Alder Sawfly

Eriocampa ovata

Identification: Larva covered by flaky white bloom. earliest NA record: ON 1908

Yellow-headed Spruce Sawfly

Euura alaskensis

serious pest of spruce trees; damages nursery crops and urban trees

Willow Apple Gall Sawfly

Euura californica

Identification: This sawfly makes the only round red/green willow leaf gall in California with lenticels (wartlike scales, tubercles). The gall protrudes on both sides of the leaf.

Euura hispidae 0

Euura hispidae

Identification: Dave Smith believes these photos represent this species: and probably For more information, see this page .

Locust Sawfly

Euura tibialis

Identification: According to Dave Smith, of the Nematus larvae feeding on black locust, N. tibialis is the green one (may have some small black dots); N. abottii is almost all black. Shares the coloration of Lopidea but do not share the ill smelling

Euura ventralis

Identification: Adult - see original description by Say 1824 in print references below. All stages - see Howard 1888 in print references below. Includes illustration of adult. may be abundant on willow in c. US & Prarie Provinces

Late Birch Leaf Edgeminer

Heterarthrus nemoratus

Identification: mine Introduced from Europe early in the 20th century ; at one time a severe pest of wild birch, now a minor aesthetic pest In the 1920s/1930s several biocontrol agents were imported, Kratochviliana laricinellae and Phanomeris phyllot

Hoplocampa marlatti

Identification: They vary from nearly all orange to nearly all black.

Leucopelmonus annulicornis

One of the few sawflies that have a white band on the antennae. The host plant is unknown. (Comment by Dave Smith)

Macrophya epinota

Identification: "Two white spots on back of head (near occiput), mesoscutellum largely white, complete white band on hind tibia. There is nothing else like this." - Dave Smith

Macrophya festana

Identification: One of only two species of Macrophya combining white antennal tips and white tarsi (the other being M. varia ). In both sexes, regions that would be have a black ground color in M. varia are rufoaurantius in M. festana , including the

Macrophya formosa

Identification: ♀: Entirely black flagellum; yellow scape; V to triangular shaped mark on prescutum; yellow scutellum; yellow hind coxae; abdomen black with reddish on parts of T4-9. ♂: Entirely black flagellum; yellow scape; V to triangular shaped

Macrophya fumator

Identification: One of about 7 species of Macrophya to occur west of the Rockies . Females typically have a distinctive red abdomen, and males have the forelegs significantly pale-marked. Both sexes have the flagellum entirely black. ♀ ♂

Macrophya goniphora

Identification: Readily distinguished by the combination of entirely black antennae, white scutellum, rufoaurantius abdomen, and whitish hind coxae.

Macrophya nigra

Identification: Females are distinctive with the combination of white antennal tips, entirely black hind tibia and tarsus, and entirely black scutellum.

Macrophya succincta

Identification: ♀: Flagellum entirely black, scape yellow, scutellum yellow, abdomen black with extensive yellow banding, hind coxa black.

Macrophya varia

Identification: One of only two species of Macrophya combining white antennal tips and white tarsi (the other being M. festana ). Appropriately for its epithet, other markings are quite variable, including the extent of pale markings around the orbit

Raspberry Sawfly

Monophadnoides rubi

Identification: "A number of genera have similar spines, but not so long and branched in M. rubi , the spines on the subspiracular lobe (second row from bottom) have the anterior spine bifurcate and the posterior spine simple; the spines on the surpe

Monophadnus pallescens

Monophadnus pallescens (Monophadnus pallescens) is a species in the family Tenthredinidae, commonly known as common sawflies, belonging to the order Hymenoptera (Ants, Bees, Wasps and Sawflies). It is classified within the subfamily Blennocampinae, t

Green Alder Sawfly

Monsoma pulveratum

European species established in eastern Canada since the early 1990s, detected in Alaska in 2009 and Washington in 2010. Now in ten western WA counties (Clark to Whatcom). Larvae feed on alders in spring and early summer, and causes severe defoliatio

Nematus abbotii

Identification: According to Dave Smith, of the Nematus larvae feeding on black locust, N. tibialis is the green one (may have some small black dots); N. abottii is almost all black.

Nematus castaneae

Identification: Key to Species (Larvae and Adults) Apparently rarely seen because various fungal diseases including chestnut blight has significantly reduced the populations of their host, American Chestnut.

Nematus erythrogaster, or similar

Nematus cf-erythrogaster

These larvae most closely match Nematus erythrogaster among the known alder-feeding sawflies, but more rearing is needed to determine whether there are other similar species.

Dusky Birch Sawfly

Nematus latitarsus

Identification: Larva is yellow-green with rows of black spots along the body; heads of mature larvae black (dull orange in Birch Sawfly, Arge pectoralis ) Key to Species (Larvae and Adults) common defoliator of birch

Pristiphora appendiculata

"A rather common sawfly on currant and distinguished from the other currant-feeding species, Nematus ribesii , by lacking black spots on the body. Widespread in North America, and probably an introduction from Europe long ago." [comment by Dave Smith

Larch Sawfly

Pristiphora erichsonii

Earliest record in our area: 1880[cite:] Repeated defoliations make trees susceptible to deadly attacks by Dendroctonus simplex Overwintering coccoons are destroyed by small mammals, especially shrews and voles. Two parasites have been imported: an i

Pristiphora litura

Identification: Females are variable in color, being partly orange as this to almost all black. Males are mostly black.

Amber-marked Birch Leaf Miner

Profenusa thomsoni

Introduced to NA early 1900s; spread westward, reached AB by 1970, reached Anchorage, AK ca. 1996

Rhogogaster nr-viridis

Identification: Separated from R. californica as follows: Head with frontal groove much shallower than antennal groove; antennal crests aligned with raised edge of frontal area. ( 3 )
