Arge ochropus, the rose sawfly, is a species belonging to the family Argidae subfamily Arginae.
The adults grow up to 7–10 millimetres (0.28–0.39 in) long and can be encountered from April to May. [1] The head and thorax are black, while the abdomen and wings are reddish orange. The larvae are yellow and bristly with black markings. [2]
This species is very similar to Athalia rosae (Tenthredinidae), but in Arge ochropus the antennae are composed of three sections, the third of which is greatly elongated, while in Athalia rosae the antennae are composed of 10–11 items. Arge pagana is mainly black above.
This sawfly is present in Europe, Asia Minor, the Caucasus, Turkmenistan, Northern Iran and Western Siberia up to Lake Baikal. [3] It has been introduced to the northeastern United States and Eastern Canada. [4]
Adults feed of nectar and pollen on Tanacetum vulgare , Angelica sylvestris and Heracleum sphondylium . This species has two generations a year. The females lay about 16–18 eggs on the rose stems. [2] Larvae feed on the leaves of some species of the genus Rosa , for example Rosa canina , Rosa majalis and Rosa pimpinellifolia . [1]
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis.
Arge pagana is a sawfly in the family Argidae. It is known by the name "large rose sawfly" although the related species Arge ochropus is also known by this name.
Diplolepis rosae is a gall wasp which causes a gall known as the rose bedeguar gall, Robin's pincushion, mossy rose gall, or simply moss gall. The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose or dog rose shrubs. The female wasp lays up to 60 eggs within each leaf bud using her ovipositor. The grubs develop within the gall, and the wasps emerge in spring; the wasp is parthenogenetic with fewer than one percent being males.
Arge cyanocrocea, the bramble sawfly, is a species of sawflies of the family Argidae, subfamily Arginae.
Tenthredo scrophulariae, the figwort sawfly is a species of the family Tenthredinidae, subfamily Tenthredininae.
Arge melanochroa is a species of the family Argidae, subfamily Arginae.
The turnip sawfly is a typical sawfly with dark green or blackish 18–25 mm long larvae that feed on plants of the brassica family, and can sometimes be a pest. It winters below the ground, emerging in early summer as a 7–8 mm adult with a mainly orange body and a black head. The adult feeds on nectar.
Abia sericea, common name club horned sawfly or scabious sawfly, is a species of sawflies belonging to the family Cimbicidae.
Spruce sawflies are various sawfly species found in North America that feed on spruce. There are multiple species of sawflies known as spruce sawflies, including species in the genera Gilpinia, Pikonema, Pristiphora, and Cephalcia. Each kind of sawfly attacks particular parts of the spruce as larvae during different times of the year.
Arge berberidis, common name berberis sawfly, is a species of sawflies belonging to the family Argidae subfamily Arginae.
Tenthredo colon is a sawfly species belonging to the family Tenthredinidae.
Tenthredo vespa is a sawfly species belonging to the family Tenthredinidae.
Tomostethus multicinctus, common name brownheaded ash sawfly, is a species of sawfly in the family Tenthredinidae that is native to southern Canada and the eastern United States. Adults of this species resemble wasps and the larvae feed on the leaves of ash trees.
Nematus oligospilus, commonly known as the willow sawfly, is a species of sawfly in the family Tenthredinidae. Native to central and northern Europe and Asia, it was first recorded in South America in the 1980s and New Zealand in 1997, and has also been introduced to Australia, South Africa and Lesotho. Its larvae feed on the leaves of various species of willow.
Diprion similis is a species of sawfly in the family Diprionidae. It is native to central and northern Europe and Asia but was accidentally introduced into North America where it has become invasive. The larvae feed on the needles of pine trees, especially those of the white pine. In North America it is known as the introduced pine sawfly or the imported pine sawfly. It is also known as the white pine sawfly because of its preference for feeding on the white pine, but this name is confusing because another sawfly, Neodiprion pinetum, whose larvae also feed on this tree, is itself known as the "white pine sawfly".
Neodiprion lecontei is a species of sawfly in the family Diprionidae native to eastern North America, commonly known as the red-headed pine sawfly or Leconte's sawfly. The larvae feed on the foliage of many species of native and imported pines. This species was named after John Lawrence LeConte, an American entomologist of the 19th century.
Eutomostethus luteiventris is a species of sawflies belonging to the family Tenthredinidae, subfamily Blennocampinae.
Eriocampa ovata, known generally as the alder sawfly or woolly alder sawfly, is a species of common sawfly in the family Tenthredinidae. The larvae feed on the leaves of the common alder and the grey alder, sometimes causing defoliation.
