The false potato beetle (Leptinotarsa juncta) is a beetle found primarily in the Mid-Atlantic and Southeastern United States. Its distribution extends to Maine.

Adult beetles emerge from the soil in the late spring or early summer and begin breeding, and a population may go through one to three generations in a summer.

The false potato beetle feeds on solanaceous weeds such as horsenettle, Solanum carolinense . It also feeds on other solanaceous plants, such as species of ground cherry or husk tomato, Physalis spp., and bittersweet, Solanum dulcamara , but no growth and reproduction occurs when feeding on the potato, Solanum tuberosum.

L. juncta can be easily confused with its congener the Colorado potato beetle, Leptinotarsa decemlineata. While the adult false potato beetle has alternating black and white strips on its back, like the Colorado potato beetle, one of the white strips in the center of each wing cover is missing and replaced by a light brown strip. The eggs are slightly larger and fewer are found in a cluster. The hump-backed larva is similar, but with only one row of dark spots on each side. The two species are apparently incapable of crossbreeding. Of the two, only the Colorado potato beetle is a serious pest. FOUND IN the mid Atlantic USA and Canada. The false potato beetle gets its name from its roundness.

The potato is a starchy tuber of the plant Solanum tuberosum and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae.

Colorado potato beetle Species of beetle

The Colorado potato beetle, also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, or the potato bug, is a major pest of potato crops. It is about 10 mm long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards.

<i>Solanum carolinense</i> Species of plant

Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States. The plant is invasive throughout much of temperate North America, as well as parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with prickles.

Tansy beetle Species of beetle

The tansy beetle is a species of leaf beetle. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration. The common name derives from the tansy plant on which they often feed as both larvae and adults. 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' and this localised population, centred on York, North Yorkshire, has been the subject of much recent research.

Cleridae Checkered beetles

Cleridae are a family of beetles of the superfamily Cleroidea. They are commonly known as checkered beetles. The family Cleridae has a worldwide distribution, and a variety of habitats and feeding preferences.

Globodera pallida is a species of nematode in the family Heteroderidae. It is well known as a plant pathogen, especially of potatoes. It is "one of the most economically important plant parasitic nematodes," causing major crop losses, and is a model organism used to study the biology of cyst nematodes. Its common names include potato cyst nematode, white potato cyst nematode, pale potato cyst nematode, potato root eelworm, golden nematode, and pale cyst nematode.

<i>Peridroma saucia</i> Species of moth

Peridroma saucia, the pearly underwing or variegated cutworm, is a moth of the family Noctuidae. The species was first described by Jacob Hübner in 1808. It is found in North and South America, Europe, Asia and Africa. The variegated cutworm feeds on many plants, especially common fruits and vegetables. The moth undergoes two to four generations per year. The development of the moth slows in colder temperatures, indicative of its migratory nature. All stages of the life cycle have a developmental threshold for temperature. The moth is known to migrate to the northern regions during warmer months, returning to the southern regions when the climate becomes colder.

<i>Solanum rostratum</i>

Solanum rostratum is a species of nightshade that is native to the United States and northern and central Mexico. Common names include buffalobur nightshade, buffalo-bur, spiny nightshade, Colorado bur, Kansas thistle, bad woman, Mexican thistle, and Texas thistle.

<i>Coleomegilla maculata</i> Species of beetle

Coleomegilla maculata, commonly known as the spotted lady beetle, pink spotted lady beetle or twelve-spotted lady beetle, is a large coccinellid beetle native to North America. The adults and larvae feed primarily on aphids and the species has been used as a biological control agent. Based on name connotation and to avoid confusion with other species also called "spotted ladybeetle", spotted pink ladybeetle is probably the most appropriate common name for this species.

Solanum chacoense is a species of wild potato. It is native to South America, where it can be found in Brazil, Bolivia, Argentina, Peru, Uruguay, and Paraguay. It "is one of the most widely distributed wild potato species." It grows as a common weed in disturbed habitat such as crop fields. It can also be found in Australia, China, the United States, England, New Zealand, and elsewhere as an introduced species.

<i>Perillus bioculatus</i> Species of true bug

Perillus bioculatus, the two-spotted stink bug or double-eyed soldier bug, is a species of insect in the family Pentatomidae. They are native to North America but have been introduced to Eastern Europe and North India. Both the larval and adult stages are specialized predators of eggs and larvae of the Colorado potato beetle. However, the first instar larvae feed by sucking the juices out of potato stems.

Henosepilachna vigintioctomaculata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird, a name also used for the closely related species, Henosepilachna vigintioctopunctata.
