Titanacris Velazquezii
''Titanacris'' is a genus of large grasshoppers in the subfamily Romaleinae and tribe Tropidacrini. They are found from southeastern Mexico, through Central and South America, ranging south to northernmost Argentina. Adult males are generally long and females long, but they are quite poorly known because they live high in the canopy of tropical forests, they are excellent fliers (not easily caught), and only ''T. albipes'' and ''T. velazquezii'' appear to regularly be attracted to artificial light at night. They are mostly green, but in flight they have conspicuously violet, red, orange-red or pink wings; their wings lack the dark rear edge and spotting seen in the closely related ''Tropidacris''. The shape of the female's ovipositor indicates that the eggs are deposited in the soil, similar to the better-known ''Tropidacris''. Taxonomy ''Titanacris'' and the closely related to ''Tropidacris'' form the tribe Tropidacrini, but the latter genus is generally better known. There a ...

Titanacris Albipes
''Titanacris albipes'', the purple-winged grasshopper, is a large species of South American grasshopper in the family Romaleidae. This species lives in the canopy of the Amazon rainforest and also extends into the Cerrado region in gallery forest. It is often attracted to artificial light during the night. Adult males are generally long and females long. Both sexes are primarily deep green and most of their wings are uniformly purple, which is conspicuous in flight and separates them from all other ''Titanacris'' species that have extensive red, orange-red or pink to their wings.

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are amongst what are possibly the most ancient living groups of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. Their front legs are shorter and used for grasping food. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a Nymph (biology), nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, a change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Tropidacris
''Tropidacris'' is a Neotropical genus of grasshopper in the family Romaleidae. They are among the largest grasshoppers in the world by length and wingspan, reaching up to and respectively. They are variably colored in green, brown, black, reddish or yellowish, and have wings that usually are conspicuously blue (''T. collaris'' and ''T. descampsi'') or red (''T. cristatus'') in flight. The gregarious and flightless nymphs have bright aposematic colors and are presumed to be toxic; a researcher who tasted one noted that it was very bitter, similar to a monarch butterfly. These locally abundant grasshoppers inhabit a wide range of habitats, from rainforests to dry open areas and lowlands to highlands. Both adults and nymphs feed on many types of plants and decaying matter, and (especially ''A. collaris'') are sometimes regarded as pests because of the considerable damage they may cause to agricultural crops, tree plantations and ornamental plants.

Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word , meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the tissues of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
