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 ...
Symptoms include mosaic pattern on the leaves, malformed leaves and flowers, elongated shoots that are often red, and sometimes thorn proliferation. The distorted growth may be mistaken for herbicide damage. [12] There is no treatment for the disease, and control is limited to controlling the vector and destroying infected plants.
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 ...
[13] This process is known as stridulation and could even shock a bird or any other predator that may attack the lily leaf beetle. [3] Lilies may first show evidence of holes chewed in the leaves from consumption, and if left unchecked rapidly progress to blackening, and total loss of the leaves, leaving only the stem.
Hosta with virus X. Hosta leaves and stems are eaten by deer, rabbits, slugs and snails, and the roots and rhizomes are eaten by voles, all of these can cause extensive damage to collections in gardens. Some varieties seem more resistant to slug damage, which is more prevalent later in the growing season, than others.
To make the cuts, grab several clusters of hosta leaves in one hand and prune the leaves with the other. Once the foliage is cut back, add a layer of compost mulch to the border.
A leafhoppers' diet commonly consists of sap from a wide and diverse range of plants, but some are more host-specific.
