Phasmatodea Tribes
The Phasmatodea (also known as Phasmida, Phasmatoptera or Spectra) are an order of insects whose members are variously known as stick insects, stick-bugs, walking sticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both dragonflies and crane flies. They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek ', meaning an apparition or phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary lines of defense in the form of startle displays, spines or toxic secretions. Stick insects from the genera '' Phryganistria'', ''Ctenomorpha'', and '' Phobaeticus'' include the world's lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pijnackeria Hispanica
''Pijnackeria hispanica'', commonly known as the Spanish walkingstick or the Spanish stick insect, is a species of Phasmid (stick insect) in the family Diapheromeridae. It is found in Spain and France. This species' color can be turquoise, brown, or green. ''P. hispanica'' usually feeds on rose leaves. This phasmid is slender with short antennae and yellow or brown eyes with a black horizontal stripe or pseudopupil In the compound eye of invertebrates such as insects and crustaceans, the pseudopupil appears as a dark spot which moves across the eye as the animal is rotated. This occurs because the ommatidia that one observes "head-on" (along their optica .... References Insect taxa Insects described in 1878 Diapheromeridae {{Phasmatodea-stub ...

Antipredator Adaptation
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle, namely by avoiding detection, warding off attack, fighting back, or escaping when caught. The first line of defence consists in avoiding detection, through mechanisms such as camouflage, masquerade, apostatic selection, living underground, or nocturnality. Alternatively, prey animals may ward off attack, whether by advertising the presence of strong defences in aposematism, by mimicking animals which do possess such defences, by startling the attacker, by signalling to the predator that pursuit is not worthwhile, by distraction, by using defensive structures such as spines, and by living in a group. Members of groups are at reduced risk of predation, despite the increased conspicuousness of a group, through improved vigilance, predator confus ...
