Canna leaf roller refers to two different Lepidoptera species that are pests of cultivated cannas. Caterpillars of the Brazilian skipper butterfly ( Calpodes ethlius ), also known as the larger canna leaf roller, cut the leaves and roll them over to live inside while pupating and eating the leaf.

Sometimes leaves are slightly distorted and puckered. Like many plants under stress, affected cannas will flower very early in the season and before the plant is full height. Over the years the canna will lose vigour and become increasingly unsightly. Some are spread by aphids and other sap sucking insects.
Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
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 ...
The giant mesquite bug (Thasus neocalifornicus) is an insect of the order Hemiptera, or the "true bugs". As a member of the family Coreidae , it is a leaf-footed bug. As the common name implies, it is a large bug that feeds on mesquite trees of the American Southwest and Northwestern Mexico.
Isotoma anglicana (Entomobryomorpha) with visible furcula Deutonura monticola (Poduromorpha). Members of the Collembola are normally less than 6 mm (0.24 in) long, have six or fewer abdominal segments, and possess a tubular appendage (the collophore or ventral tube) with reversible, sticky vesicles, projecting ventrally from the first abdominal segment.

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 ...
Small sized with spreading habit and thick rhizomes (these up to 3 cm in diameter). Green ovate leaves; green triangular stems; upright spikes with flowers of yellow petals with a wide red margin; staminodes are long and narrow, edges regular; capsules globose.
