The Japanese beetle is a species of scarab beetle. The adult measures 15 mm (0.6 in) in length and 10 mm (0.4 in) in width, has iridescent copper-colored elytra and a green thorax and head. It is not very destructive in Japan, where it is controlled by natural predators, but in North America, it is a noted pest of about 300 species of plants including rose bushes, grapes, hops, canna, crape myrtles, birch trees, linden trees, and others.
A corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Philodendron is a large genus of flowering plants in the Araceae family. As of September 2015, the World Checklist of Selected Plant Families accepted 489 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the Araceae family. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo- or "love, affection" and dendron or "tree". They are commonly called by their generic name.
Roridula is a genus of evergreen, insect-trapping shrubs, with two species, of about 1⅓–2 m. It is the only genus in the family Roridulaceae. It has thin, woody, shyly branching, upright, initially brown, later grey stems, with lance- to awl-shaped leaves crowded at their tips. The star-symmetrical flowers consist from the outside in of five, green or reddish, free sepals, alternating with five white, pink or purple, free petals. Further to the middle and opposite the sepals are five stamens with the anthers initially kinked down. These suddenly flip up if the nectar-containing swelling at its base is being touched. The center of the flower is occupied by a superior ovary. The leaves and sepals carry many sticky tentacles of different sizes, that trap insects. Roridula does not break down the insect proteins, but bugs of the genus Pameridea prey on the trapped insects. These later deposit their feces on the leaves, which take up nutrients from the droppings. The species can be found in the Western Cape province of South Africa. They are commonly known as dewstick or fly bush in English and vlieëbos or vlieëbossie in Afrikaans.
Phyllophaga is a very large genus of New World scarab beetles in the subfamily Melolonthinae. Common names for this genus and many other related genera in the subfamily Melolonthinae are May beetles, June bugs, and June beetles. They range in size from 12 to 35 mm and are blackish or reddish-brown in colour, without prominent markings, and often rather hairy ventrally. These beetles are nocturnal, coming to lights in great numbers.
A leaf miner is any one of a large number of species of insects in which the larval stage lives in and eats the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies and flies (Diptera), though some beetles also exhibit this behavior.
Ipomoea pandurata, known as man of the earth, wild potato vine, manroot, wild sweet potato, and wild rhubarb, is a species of herbaceous perennial vine native to North America. It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.
Donacia is a large genus of aquatic leaf beetles in the subfamily Donaciinae. Like other members of that subfamily, the beetles have long antennae. They are active and able to fly. Larvae feed on submerged portions of aquatic plants, such as water lilies, and breathe oxygen from plant vessels. Adults live on surface parts of the same plants.
Sagittaria cuneata is a species of flowering plant in the water plantain family known by the common name arumleaf arrowhead or duck potato. Like some other Sagittaria species, it may be called wapato. It is native to much of North America, including most of Canada as well as the western and northeastern United States.
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.
Donacia semicuprea is a species of leaf beetles of the subfamily of Donaciinae.
Donacia magnifica is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.
Donacia tuberculata is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.
Donacia rugosa is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.
Donacia assimilis is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.
Donacia hirticollis is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.

Donacia piscatrix is a species of aquatic leaf beetle in the family Chrysomelidae. It is found in North America.
