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. Like charges repel, which means that electrons repel other electrons and protons repel other protons. In addition, unlike charges attract which means that electrons and protons are attracted to each other. 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. [26] Life cycle [ edit ] Mating pair of Anisomorpha buprestoides Dossey, Aaron (December 2010).

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.

Once the eggs turn into nymphs, they’ll live underground for 1-3 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. Anatomy Randolph, Vance (2012). Ozark Magic and Folklore. Dover Publications. ISBN 978-1-306-33958-2. OCLC 868269974. Atoms have an equal amount of protons and electrons. Each electron has a negative charge and each proton has a positive charge. These two charges are equal, which means that each atom has zero net charge. As a result, it is electrically neutral. Osmond, Meredith (1998). "Chapter 8: Fishing and Hunting Implements".

Retrieved 9 February 2020. 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]
Defensive Adaptations
Phasmatodea eggs resemble seeds in shape and size and have hard shells. They have a lid-like structure called an operculum at the anterior pole, from which the nymph emerges during hatching. The eggs vary in the length of time before they hatch which varies from 13 to more than 70 days, with the average around 20 to 30 days. [16] Some species, particularly those from temperate regions, undergo diapause, where development is delayed during the winter months. Diapause is initiated by the effect of short day lengths on the egg-laying adults or can be genetically determined. Diapause is broken by exposure to the cold of winter, causing the eggs to hatch during the following spring. Among species of economic importance such as Diapheromera femorata, diapause results in the development of two-year cycles of outbreaks. [29] Eggs of various phasmid species (not to scale)
