Galerucella lineola is a species of leaf beetle in the family Chrysomelidae.
Galerucella lineola can reach a length of 4–5 millimetres (0.16–0.20 in). The body is almost cylindrical. The basic color is brownish-yellow with a darker spot on the pronotum and on the elytra. The antennae are black. It has a black underside. The legs are slightly lighter. The larvae are gray-white to brownish and resemble small caterpillars.
Food plants include Salix alba , Salix viminalis , Salix caprea , Salix pentandra , Salix cinerea , Salix myrsinifolia , Salix fragilis , Populus nigra , Corylus avellana , Alnus glutinosa , Betula pendula , and Alnus incana .
These beetles are considered by some a pest and can in some years do great damage to the foliage gnawing holes in the leaves.
This species is widespread in the Palearctic realm from Ireland to Japan, in the Near East, and in North Africa.
Galerucella lineola can be found along the banks of watercourses, ponds and lakes, from lowlands up to foothills.
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
Lythrum salicaria or purple loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia.
The blue willow beetle, formerly Phyllodecta vulgatissima, is a herbivourous beetle of the family Chrysomelidae. It is dark with a metallic sheen that ranges from a blue color to bronze. It is distinguished from P. vitellinae by the latter more commonly displaying bronze coloration. European Phratora species can be distinguished based on morphology of female genitalia. The larvae undergo three instar stages from hatching to pupation. This beetle is found throughout Europe and Scandinavia, and occurs in China.
The grey dagger is a moth of the family Noctuidae.
The Galerucinae are a large subfamily of the leaf beetles (Chrysomelidae), containing about 15,000 species in more than 1000 genera, of which about 500 genera and about 8000 species make up the flea beetle tribe Alticini.
Agelastica alni, the alder leaf beetle, is a species of leaf beetle (Chrysomelidae) in the genus Agelastica. Agelastica alni is distributed in Europe, the Caucasus, Siberia, north-eastern Kazakhstan, and in the 19th century was introduced to the United States.
Coleophora anatipennella is a moth of the case-bearer family (Coleophoridae).
Clytra laeviuscula, the ant bag beetle, is a species of short-horned leaf beetles belonging to the family Chrysomelidae, subfamily Cryptocephalinae.
Galerucella calmariensis is a species of leaf beetle in the family Chrysomelidae. It is commonly known as the black-margined loosestrife beetle and is native to Europe and Asia where both adults and larvae feed on purple loosestrife. It has been introduced in North America as a biological control agent for purple loosestrife.
Parasyrphus nigritarsis is a species of hoverfly, from the family Syrphidae, in the order Diptera. It is known from northern Europe and North America, and has been considered to be a rare species in parts of its range. Adults visit flowers as a source of nutrition, and females lay their eggs on clutches of eggs of leaf beetles. When the Parasyrphus larvae hatch, they first consume leaf beetle eggs and then consume immature beetles until they reach the pupal stage. This species is related to hoverflies that prey on aphids as larvae, and has been investigated in studies of chemical ecology and food web ecology.
Salix arbusculoides is a species of flowering plant in the willow family known by the common name little tree willow. It is native to northern North America, where its distribution extends across Alaska and most of Canada.
Clytra quadripunctata is a species of leaf beetle in the subfamily Cryptocephalinae. Its common name is Four spotted leaf beetle.
Galerucella is a genus of leaf beetles in the family Chrysomelidae described by George Robert Crotch in 1873. It is widely distributed but absent in the Neotropics. Some species feed on waterlilies and are used as biocontrol of introduced, invasive waterlilies. Galerucella tenella feed on strawberry plants.
Pyrrhalta is a genus of beetles in the leaf beetle family, Chrysomelidae. Species are distributed throughout much of the world, including much of the Northern Hemisphere and the Australian region.
Phratora vitellinae, the brassy leaf beetle, formerly Phyllodecta vitellinae, is a beetle of the family Chrysomelidae found in Europe and Asia. It feeds on Populus and Salix species. The evolution of its host plant preferences and the mechanism by which it uses host plant chemicals to make a larval defensive secretion have been the subject of intense study by research groups in Europe and the Nordic countries.
Labidostomis cyanicornis is a species of short-horned leaf beetles belonging to the family Chrysomelidae, subfamily Cryptocephalinae, tribe Clytrini.
Luperus viridipennis is a species of skeletonizing leaf beetle belonging to the family Chrysomelidae, subfamily Galerucinae.
Phratora tibialis is a species of leaf beetle found in Europe and parts of Asia. This beetle is found on willows and the chemistry and production of its larval defensive secretions and host plant relationships have been studied extensively.
Phratora polaris is a species of leaf beetle found in the Nordic regions of Europe., occasionally in Scotland, and Iceland. Some authors have recorded it in central Europe, especially in the Alps. Historically, this species has occurred in Greenland. This beetle is found on willow (Salix) species in the southern part of its range. Populations in Lapland feed on birch.
Galerucella placida, is a species of leaf beetle found in South Asia, Southeast Asia and Australia. It is widely used as a bio-control agent in many rice and wheat fields to control weeds.
