Psyllid
Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flower ...

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term is al ...

Lerp (biology)
In biology, a lerp is a structure of crystallized honeydew produced by larvae of psyllid bugs as a protective cover. These animals are commonly referred to as lerp insects, of which there are over 300 species in Australia. Lerps are energy rich, consisting mostly of starch, with some proteins and fats. They are eaten by flying foxes, possums and birds such as pardalotes and honeyeaters The honeyeaters are a large and diverse family, Meliphagidae, of small to medium-sized birds. The family includes the Australian chats, myzomelas, friarbirds, wattlebirds, miners and melidectes. They are most common in Australia and New Gui .... The word is derived from the Australian Aboriginal language Wemba-Wemba. Lerps were traditionally eaten by Indigenous people, and could be stored as dry balls for future use.

Sternorrhyncha
The Sternorrhyncha suborder of the Hemiptera contains the aphids, whiteflies, and scale insects, groups which were traditionally included in the now-obsolete order "Homoptera". "Sternorrhyncha" refers to the rearward position of the mouthparts relative to the head. Distributed worldwide, all members of this group are plant-feeders, many considered pests feeding on major crops and ornamental plants. Many exhibit modified morphology and/or life cycles, including phenomena such as flightless morphs, parthenogenesis, sexual dimorphism, and eusociality. Phylogeny The phylogeny of the extant Sternorrhyncha, inferred from analysis of small subunit (18S) ribosomal RNA, is shown in the cladogram. The evolutionary position of several fossil taxa are unclear. A suggested phylogeny is: Groups Well-known groups in the Sternorrhyncha include: * aphids – (Aphididae) * woolly and gall-making aphids (Eriosomatinae) * pine and spruce aphids (Adelgidae) * phylloxerans (Phylloxeridae, ...

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, colon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
