The tansy beetle is a species of leaf beetle. The common name derives from its main foodplant, Tansy, but it can also use other wetland plants such as Gypsywort and Water Mint. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of Tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining. In the United Kingdom it is designated as 'Nationally Rare'. The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire. Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
Apocynum, commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek ἀπόκυνονapókunon, from ἀπο-apo- "away" and κύωνkúōn "dog", referring to dogbane, which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe.
Apocynum cannabinum is a perennial herbaceous plant that grows throughout much of North America—in the southern half of Canada and throughout the United States. It is poisonous to humans, dogs, cats, and horses. All parts of the plant are toxic and can cause cardiac arrest if ingested. Some Lepidoptera feed on this plant, such as the hummingbird moth.
Acalymma vittatum, the striped cucumber beetle, is a beetle of the family Chrysomelidae and a serious pest of cucurbit crops in both larval and adult stages. The striped cucumber beetle has a distinctive appearance, displaying a yellow-colored elytra with black stripes. It is distributed from eastern North America to the Rocky Mountains and can be found as far south as Mexico and as far North as southern Canada. In western North America, past the Rocky Mountains, the striped cucumber beetle is replaced by Acalymma trivittatum, a duller colored species often with grayish or pale white elytra rather than yellow.
The queen butterfly is a North and South American butterfly in the family Nymphalidae with a wingspan of 80–85 mm. It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests.
Apocynum androsaemifolium, the fly-trap dogbane or spreading dogbane, is a flowering plant in the Gentianales order. It is common across Canada and much of the United States excepting the deep southeast.
Cycnia tenera, the dogbane tiger moth or delicate cycnia, is a moth in the family Erebidae. It occurs throughout North America, from southern British Columbia to Nova Scotia southwards to Arizona and Florida. The species is distasteful and there is evidence that it emits aposematic ultrasound signals; these may also jam bat echolocation, as the functions are not mutually exclusive.
Euchaetes egle, the milkweed tiger moth or milkweed tussock moth, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by Dru Drury in 1773. It is a common mid- through late summer feeder on milkweeds and dogbane. Like most species in this family, it has chemical defenses it acquires from its host plants, in this case, cardiac glycosides. These are retained in adults and deter bats, and presumably other predators, from feeding on them. Only very high cardiac glycoside concentrations deterred bats as predators. Adults indicate their unpalatability to bats with ultrasonic clicks from their tymbal organs.
Chrysochus cobaltinus, the cobalt milkweed beetle or blue milkweed beetle, is a member of the diverse family leaf beetles (Chrysomelidae). It is named after its cobalt-blue exoskeleton, which makes it easy to spot and distinguish, and its tendency to feed off milkweed plants. It occurs in the Western United States and British Columbia.
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance.
Chrysomela populi is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae.
Cerotoma trifurcata is a species of beetle in the Chrysomelidae family that can be found in the Eastern and West United States.
The sumac flea beetle, Blepharida rhois, is most commonly found in North America and is a member of the herbivorous beetle family, Chrysomelidae. More specifically, this beetle is part of the Alticinae subfamily, a highly diverse subfamily that includes more than 1000 species in 550 genera. Members of the Chrysomelidae family are distinguished by their enlarged metafemora and their ability to jump up to 100 times their length. This gives the beetle the ability to catapult jump in order to escape approaching predators. This ability has led to the common name of “flea beetle.” Both larvae and adults are typically a quarter of an inch long. While adults are cream colored with irregular reddish patterns, larvae are typically gray with yellow stripes.
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.
Ophraella communa, common name ragweed leaf beetle, is a species of beetles belonging to the family Chrysomelidae.
Phaedon cochleariae is a non-social, holometabolous species of leaf beetle native to Europe.
Chrysochus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America, Europe and Asia.
Chrysochus asclepiadeus is a member of the leaf beetle subfamily Eumolpinae. It is considered the type species of the genus Chrysochus, though it has sometimes been placed within the genus Eumolpus. It is the only species of Chrysochus distributed in the western Palaearctic. It is mainly found in Europe, though it is also known from Kazakhstan and Turkey in Asia.
Chelymorpha alternans, the neotropical tortoise beetle, is a species of leaf beetle in the family Chrysomelidae and the Cassidinae subfamily. Its name is derived from its body shape and patterning. The first half of its name, Chelymorpha, means 'turtle/tortoise form' while the second part, alternans, means 'alternating'.
Altica cirsicola is a species of flea beetle from the genus Altica, which belongs to the family Chrysomelidae. A. cirsicola is found throughout East Asia. Adults feed exclusively on plants from the genus Cirsium. This food resource provides the species with the opportunity to create holes in the leaves of the plant, which helps to provide the beetles with camouflage and protection from predators.
