Phreatia crassiuscula, commonly known as the green caterpillar orchid, [2] is a plant in the orchid family and is an epiphyte or lithophyte with three to six fleshy, channelled leaves in a fan-like arrangement. Up to sixty tiny white, cream-coloured or greenish flowers are arranged along a curved flowering stem. It is endemic to tropical North ...
[2] [3] The emerging caterpillars, also known as the greenstriped mapleworm, mainly feed on the leaves of their host maple trees, particularly red maple, silver maple, and sugar maple. Since the caterpillars eat the entire leaf blade, in dense populations, caterpillars have been known to defoliate trees, resulting in aesthetic rather than ...
The larvae (or caterpillars) emerge in April and initially eat the buds of oak trees and young leaves inside them. [1] [6] When fully grown, the larvae are between 25 and 29 millimetres (0.98 and 1.14 in) long with a body that can be yellow-green or darker shades of green.
Caterpillars cause much damage, mainly by eating leaves. The propensity for damage is enhanced by monocultural farming practices, especially where the caterpillar is specifically adapted to the host plant under cultivation. The cotton bollworm causes enormous losses. Other species eat food crops.
A tail-like spine protruding from the back of the body is a typical for sphingid moth caterpillars, known as “hornworms”. [2] This horn, which may sometimes be yellow and have a black tip, is not a stinger, and the caterpillars are not harmful to humans. [7] The larvae can also sometimes be lime green and black.
A larva (or caterpillar) eating an oak leaf. Acleris semipurpurana is found in the eastern United States and adjoining portions of southeastern Canada.It has been found in US states ranging from New York, Massachusetts, Connecticut and Pennsylvania in the northeast to Minnesota and Texas in the west, as well as the Canadian province of Ontario.
Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
Caterpillars of this family are large and are most often hairy, especially on their sides. Most have skin flaps on their prolegs and a pair of dorsal glands on their abdomens. They feed on leaves of many different trees and shrubs, and often use these same plants to camouflage their cocoons. Some species are called tent caterpillars due to ...
