Wedmann, Sonja; Bradler, Sven; Rust, Jes (2006). "The first fossil leaf insect: 47 million years of specialized cryptic morphology and behavior". PNAS. 104 (2): 565–569. doi: 10.1073/pnas.0606937104. PMC 1766425. PMID 17197423. The Phasmatodea life cycle is hemimetabolous, proceeding through a series of several nymphal instars. Once emerged, a nymph will eat its cast skin. Adulthood is reached for most species after several months and many molts. The lifespan of Phasmatodea varies by species, but ranges from a few months to up to three years.

Did you know that ants carry the eggs of the Spiny Leaf Insect down into their nests, protecting them from predators? When they hatch, the babies look and behave like ants until they can escape the nest and climb into a tree. Nymphs will eventually molt (form a new skin under the old one) into adults, revealing a green or brown, slow-moving leaf mimic. Females live for another 18 months or so, while males only live for 6-8 more months. AnatomyDescription [ edit ] Phobaeticus serratipes Female Phobaeticus chani, the world's second-longest insect.

Some people have been playing on game controllers for so long that they find it hard to adapt to the newer technology. It's not surprising though, considering you can hold the controller in both hands quite comfortably and all the functions are at your fingertips.

Phasmida is the oldest and simplest name, first used by Leach in 1815 in "Brewster’s Edinburgh Encyclopaedia" volume 9, p.119, and widely used in major entomological textbooks, dictionaries and many scientific papers and books on phasmids. As there is no compulsion to select the "grammatically correct" name [which some argue is Phasmatodea Jacobson & Bianchi, 1902], selection of a long established (and simple) name is reasonable, although the probability of persuading all colleagues to agree on the use of Phasmida is unlikely.Randolph, Vance (2012).

U.S. Government Printing Office. pp.97–98. In a seemingly different method of defense, many species of Phasmatodea seek to startle the encroaching predator by flashing bright colors that are normally hidden, and making a loud noise. [19] When disturbed on a branch or foliage, some species, while dropping to the undergrowth to escape, will open their wings momentarily during free fall to display bright colors that disappear when the insect lands. Others will maintain their display for up to 20 minutes, hoping to frighten the predator and convey the appearance of a larger size. Some, such as Pterinoxylus spinulosus, accompany the visual display with the noise made by rubbing together parts of the wings. [19] a b Costa, James T. (2006). The Other Insect Societies.

When the wand touches the mylar strips they gain the same charge as the wand. For example, if the wand is negatively charged it will transfer excess electrons to the mylar strips and they too will become negatively charged. If the wand is positively charged it will "pull" electrons from the mylar strips and they too will become positively charged. The like charges contained inside the mylar strips repel each other which causes the mylar itself to expand as a result. And at the same time the like charge on the wand and mylar strips cause them to repel each other hence producing the levitation effect. If you wish to return your item to Robert Dyas, you can do so by one of the following methods: 1. Request a Collection via Robert Dyas Customer Services Some species are equipped with a pair of glands at the anterior (front) edge of the prothorax that enables the insect to release defensive secretions, including chemical compounds of varying effect: some produce distinct odors, and others can cause a stinging, burning sensation in the eyes and mouth of a predator. [21] The spray often contains pungent-smelling volatile metabolites, previously thought to be concentrated in the insect from its plant food sources. However, it now seems more likely that the insect manufactures its own defensive chemicals. [22] Additionally, the chemistry of the defense spray from at least one species, Anisomorpha buprestoides, has been shown to vary [22] based on the insect's life stage or the particular population it is part of. [23] This chemical spray variation also corresponds with regionally specific color forms in populations in Florida, with the different variants having distinct behaviors. [24] The spray from one species, Megacrania nigrosulfurea, is used as a treatment for skin infections by a tribe in Papua New Guinea because of its antibacterial constituents. [25] Some species employ a shorter-range defensive secretion, where individuals bleed reflexively through the joints of their legs and the seams of the exoskeleton when bothered, allowing the blood ( hemolymph), which contains distasteful compounds, to discourage predators. Another ploy is to regurgitate their stomach contents when harassed, repelling potential predators.

When threatened, some phasmids that are equipped with femoral spines on the metathoracic legs ( Oncotophasma martini, Eurycantha calcarata, Eurycantha horrida, Diapheromera veliei, Diapheromera covilleae, Heteropteryx dilatata) respond by curling the abdomen upward and repeatedly swinging the legs together, grasping at the threat. If the menace is caught, the spines can, in humans, draw blood and inflict considerable pain. [16]
Defensive Adaptations
When a substance has a negative charge it has an excess number of electrons. That is, the number of electrons in the substance is greater than the number of protons. When a substance has a positive charge it has an excess number of protons. That is, the number of protons in the substance is greater than the number of electrons.
