Succisa Pratensis
''Succisa pratensis'', also known as devil's-bit or devil's-bit scabious, is a flowering plant in the honeysuckle family Caprifoliaceae. It differs from other similar species in that it has four-lobed flowers, whereas '' Scabiosa columbaria'' (small scabious) and ''Knautia arvensis'' (field scabious) have five lobes and hence it has been placed in a separate genus in the same family. It also grows on damper ground. Name Species of scabious were used to treat scabies, and other afflictions of the skin including sores caused by the bubonic plague. The word scabies comes from the Latin word for "scratch" (scabere). In folk tales, the short black root was bitten off by the devil, for various reasons: anger at the plant's ability to cure these ailments, anger against the Virgin Mary, or as part of some 'devilish plot'. The Latin specific epithet ''pratensis'' literally means "of the meadow". Description ''Succisa pratensis'' is a herbaceous perennial up to 1m tall, growing from a b ...

Gall Midge
Cecidomyiidae is a family of diptera, flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the Order (biology), order Fly, Diptera, and have long Antenna (biology), antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 Genus, genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A Metabarcoding, DNA metabarcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a st ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Knautia Arvensis
''Knautia arvensis'', commonly known as field scabious, is a herbaceous perennial species of flowering plant in the honeysuckle family Caprifoliaceae. Description It is a perennial plant that grows between . It prefers grassy places and dry soils, avoiding heavy soils, and flowers between May and August. The flowers are borne on inflorescences in the form of heads; each head contains many small florets. The head is flatter than in similar species, such as Succisa pratensis, devil's bit scabious (''Succisa pratensis'') and Scabiosa columbaria, small scabious (''Scabiosa columbaria''). There are 4 stamens in each floret, and 1 notched long stigma. The fruit is nut like, cylindrical and hairy, in size. It has a tap root. The stem has long stiff hairs angled downwards. The leaves form a basal Rosette (botany), rosette, are paired on the stem, the lowest typically long, spear shaped, whereas the upper are smaller. There are no stipules. Ecology It is occasionally used by the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cecidomyiinae
The Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. Some of the herbivorous species are inquilines, developing in galls that were initiated by a different midge species. Most species in the genus '' Macrolabis'' and the tribes Trotteriini and Camptoneuromyiini are inquilines, but there are also many inquiline species in genera that are predominantly gall-inducing (such as '' Dasineura'' and '' Lasioptera''). Predatory and parasitoid species comprise about 12% of the Cecidomyiinae. Larvae of these species attack other arthropods - there are known predators of mites, aphids, scale insects, dragonfly eggs, and endoparasitoids of Hemiptera. Most are found in the tribes Aphidoletini and Lestodiplosini. Fungivores make up much of the remainder of the subfamily, indicating the retention of (or reversion to) the ancestral food source.
