Its underside, legs, eyes, antennae and head are all black. It has large eyes, a slim thorax, and a wide abdomen. [3] Each antenna is made up of 11 segments. The eyes are notched and there are two grooves on the thorax. [4] This lily beetle may be confused with the cardinal beetle (Pyrochroa serraticornis), which also has red elytra and a black ...
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 average length is 16–20 millimetres (0.63–0.79 in) with males being smaller than females. They are able to fly, making a buzzing noise when airborne. Western conifer seed bugs are somewhat similar in appearance to the wheel bug Arilus cristatus and other Reduviidae (assassin bugs).
A leafhoppers' diet commonly consists of sap from a wide and diverse range of plants, but some are more host-specific. Leafhoppers mainly are herbivores, but some are known to eat smaller insects, such as aphids, on occasion. A few species are known to be mud-puddling, but as it seems, females rarely engage in such behavior. Many species are ...
Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. [1] It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.
They generally feed upon plants belonging to the plant orders Rosales and Sapindales, and spend most of their lives in tree leaves and stems. [6] [8] They exhibit incomplete metamorphosis and have lifespans that can be several years. Some tessaratomids guard their eggs and nymphs from predators which may include parasitoid wasps and assassin bugs.
Easily recognizable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug or squash bug). [a] [1] Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. It has also been reported from the United ...
