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 φάσμα phasma , meaning an apparition or phantom , referring to their resemblance to vegetation while in fact ...
Leaves show a characteristic curling, similar to damage caused by viruses. Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions.
The family Phylliidae (often misspelled Phyllidae) contains the extant true leaf insects or walking leaves, which include some of the most remarkably camouflaged leaf mimics (mimesis) in the entire animal kingdom. They occur from South Asia through Southeast Asia to Australia. Earlier sources treat Phylliidae as a much larger taxon, containing ...
The larvae feed for up to 24 days, beginning underneath the leaf then working up the rest of the plant, and cause the most damage. Their preferred feeding locale is underneath the leaf or at the node where the leaf meets the stem. They then burrow in the ground to pupate in a cocoon of soil bound with saliva. In about 20 days they emerge as ...
Imidacloprid also exhibits excellent translaminar movement in plants and can penetrate the leaf cuticle and move readily into leaf tissue. [ 29 ] Since imidacloprid is effective at very low levels (nanogram and picogram), it can be applied at much lower concentrations (e.g., 0.05–0.125 lb/acre or 55–140 g/ha) than other insecticides.
The stem is usually red late in the season. There is an upright, erect central stem early in the season, which changes to a spreading, horizontal form later with the weight of the berries. The plant dies back to the roots each winter. The stem has a chambered pith. Leaves: The leaves are alternate with coarse texture with moderate porosity ...
Like many stick insects, E. tiaratum actively sways back and forth or side to side when disturbed or when there is a gust of wind, with a frequency distribution like foliage rustling in the wind. The swaying behaviour may be motion crypsis, preventing detection by predators, or motion masquerade, promoting misclassification (as something other ...
