Hoplocampa Testudinea
''Hoplocampa testudinea'', the apple sawfly or European apple sawfly, is a species of sawfly in the family Tenthredinidae. It is native to Europe but has been accidentally introduced into North America where it became invasive. The larvae feed inside the developing fruits of the apple tree. Description The adult apple sawfly is up to long with a brownish-black head and thorax and a brown abdomen. The larva is a caterpillar-like grub with a brown head and white body, growing to about when fully developed. It can be distinguished from the codling moth (''Cydia pomonella'') larva by being creamy-white, with seven pairs of abdominal legs, while the latter is pinkish-white and has five pairs. The sawfly larva is active in the fruits two or three weeks earlier in the season than the codling larva. Distribution Native to Europe, this sawfly is widespread between 60° and 40° north latitude. Populations are also known in the western areas of the former USSR and in northern Turkey. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positioned so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parthenogenesis
Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized Gametophyte, egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg. Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Black Prune Tree Hoplocampe
Black is a color which results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates. Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches, and magic. In the 14th century, it was worn by royalty, clergy, judges, and government officials in much of Europe. It became the color worn by English romantic poets, businessmen ...

Hoplocampa Flava
''Hoplocampa flava'', commonly referred to as the "plum sawfly" is a species of ''Hoplocampa'' sawfly. It has been found near the Mediterranean basin, Western Europe, Estonia, Latvia, Lithuania, the Caucasus and from Eastern Russia to the Ural Mountains. It has been known to be locally common in these areas. It is a common pest of plum orchards. Morphology The adult fly has a brown-yellow coloring and is in length; it has 9 segmented antennae, with a similar yellowish color. It has transparent wings with brownish-yellow veins. Its larvae are a whitish color and are around 9 to 11 mm long, with slightly curved , brownish (sometimes orange/yellowish green) and have three pairs of thoracic legs and 7 pairs of abdominal prolegs. Life cycle ''Hoplocampa flava'' is known to nest in the flowerbuds of plum, cherry plum, cherry, apricot, or sloe. Adults will plant eggs in the buds, following the hatch the larvae burrow into the developing fruits because of this the fruits secrete a oozy ...
