Nematus leucotrochus is a species of sawfly in the family Tenthredinidae, known as the pale-spotted gooseberry sawfly. Widespread throughout central and northern Europe, this insect is best known as a pest of gooseberries. The larvae feed on the foliage of the plant, defoliating it. Unlike Nematus ribesii , the common gooseberry sawfly, the species has a single brood. Adults appear in early May and larvae in May and June. [1]

Gooseberry is a common name for many species of Ribes, as well as a large number of plants of similar appearance. The berries of those in the genus Ribes are edible and may be green, orange, red, purple, yellow, white, or black.

<span class="mw-page-title-main">Sawfly</span> Suborder of insects

Sawflies are wasp-like insects that are in 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.

<span class="mw-page-title-main">Xyelidae</span> Family of sawflies

The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are to be regarded as living fossils since they represent one of the oldest lineages of insects and include still extant forms.

<span class="mw-page-title-main">Diprionidae</span> Family of sawflies

The Diprionidae are a small family of conifer-feeding sawflies restricted to the Northern Hemisphere, with some 140 species in 13 genera. Larvae are often gregarious, and sometimes there can be major outbreaks, thus these sawflies can be major forest pests at times. These sawflies have the ability to compromise the health and ecological balance of forests. When the temperatures begin to rise, the sawflies become strengthened pests to these conifers. In doing so, they cause damage to a certain extent.

<span class="mw-page-title-main">Tenthredinidae</span> Family of 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.

<i>Nematus ribesii</i> Species of sawfly

Nematus ribesii is a species of sawfly in the family Tenthredinidae. English names include common gooseberry sawfly and imported currantworm. This insect is best known as a pest of gooseberries. The larvae feed on the foliage of the plant, often defoliating it completely.

The English name gooseberry sawfly refers to at least three species of sawfly:

<i>Neodiprion sertifer</i> Species of sawfly

Neodiprion sertifer, the European pine sawfly or red pine sawfly, is a sawfly species in the genus Neodiprion. Although native to Europe, it was accidentally introduced to North America in 1925.

<i>Diprion pini</i> Species of sawfly

Diprion pini, the common pine sawfly, is a sawfly species in the family Diprionidae. It is a serious pest of economic forestry, capable of defoliating large areas of pine forest. It occurs throughout Europe and Russia.

<i>Nematus</i> Genus of sawflies

Nematus is a genus of sawfly in the family Tenthredinidae. Some of its species, including Nematus leucotrochus, Nematus olfaciens and Nematus ribesii, eat the leaves of fruit bushes and trees, and can be serious pests.

<i>Nematus spiraeae</i> Species of sawfly

Nematus spiraeae is a species of sawfly in the family Tenthredinidae, known as the aruncus sawfly and sometimes the spiraea sawfly. It is native to central and northern Europe and was first recorded in Britain in 1924. Its larvae feed on the leaves of goat's beard.

Hoplocampa testudinea, the apple sawfly or European apple sawfly, is a species of sawfly in the family Tenthredinidae. It is native to Europe but has been accidentally introduced into North America where it became invasive. The larvae feed inside the developing fruits of the apple tree.

<i>Nematus oligospilus</i> Species of sawfly

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.

<i>Diprion similis</i> Species of sawfly

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 pinetum is a species of sawfly in the family Diprionidae. It is commonly known as the white pine sawfly, a name sometimes also applied to Diprion similis, because the larvae of both species feed on the needles of the white pine.

<i>Neodiprion lecontei</i> Species of 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.

<i>Acantholyda erythrocephala</i> Species of sawfly

Acantholyda erythrocephala is a species of sawfly in the family Pamphiliidae commonly known as the red-headed pine sawfly or the pine false webworm. Native to Europe, it has been introduced into North America where it has become invasive.

Nematus ventralis, the willow sawfly, is a species of common sawfly in the family Tenthredinidae.

Lathrolestes luteolator is a species of wasp in the family Ichneumonidae. it is native to North America and is a parasitoid of various species of sawfly larvae. In the 1990s, it started to parasitise the larvae of the invasive amber-marked birch leaf miner in Alberta. When this pest spread to Alaska, the wasp was used in biological pest control.

Hoplocampa flava, commonly referred to as the "plum sawfly" is a species of Hoplocampa sawfly. It has been found near the Mediterranean basin, Western Europe, Estonia, Latvia, Lithuania, the Caucasus and from Eastern Russia to the Ural Mountains. It has been known to be locally common in these areas. It is a common pest of plum orchards.
