Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Root Fly
''Delia radicum'', known variously as the cabbage fly, cabbage root fly, root fly or turnip fly, is a pest of crops. The larvae of the cabbage root fly are sometimes known as the cabbage maggot or root maggot. ''Delia brassicae'' (or ''Hylemya brassicae'') was the most common name in literature prior to 1981. The adult flies are about 1 cm long and are grey in colour, but otherwise resemble the common house fly. The flies can be found all over Europe. After overwintering as pupae in the soil, the flies emerge in spring, feed on nectar, and lay eggs close to plants of the genus ''Brassica''. The eggs are white and about 1 mm in diameter. They hatch into white maggots after about six days and the larvae feed for about three weeks on the roots and stems of the cabbage plants. After this, the larvae are typically 0.9 to 1 cm in length and form reddish-brown pupae which hatch into adult flies after around 20 days. This species is univoltine Voltinism is a term used in ...

Delia (fly)
''Delia'' flies are members of the Anthomyiidae family within the superfamily Muscoidea. The identification of different species of ''Delia'' can be very difficult for non-specialists as the diagnostic characteristics used for immature and/or female specimens may be inconsistent between species. Past taxonomic keys were not as comprehensive in their identification of ''Delia'' specimens; they were either too reliant on genetic characteristics, focused solely on a specific life stage, or were focused only on certain species. However current taxonomic keys aim to be more thorough by not only including morphological diagnostics for males, females, and immature specimens of various species, but also their genetic make-up or molecular barcode. Certain ''Delia'' species are of great economic importance as they are agricultural pests. The larvae of these flies, which tunnel into roots and stems of host plants, can cause considerable yield losses. Although most members of this genus have ...

Anthomyiidae
The Anthomyiidae are a large and diverse family (biology), family of Muscoidea fly, flies. Most look rather like small houseflies. Most species are drab grey to black. Many ''Pegomya'' are yellow, and some members of the genus, genera ''Anthomyia'' and ''Eutrichota'' are patterned in black-and-white or black-and-silvery-grey. Most are difficult to identify, apart from a few groups such as the Kelp fly, kelp flies that are conspicuous on beaches. The name Anthomyiidae was derived from Greek ''anthos'' (flower) plus ''myia'' (a fly). Some species are commonly called "root-maggots", as the larvae are found in the stems and roots of various plants. As larvae, some also feed on decaying plant material. The well-known grey "seaweed flies" or "kelp flies" (''Fucellia'') are examples. Others are scavengers in such places as birds' nests; yet other species are leaf miners; the family also includes inquilines, commensals, and parasite, parasitic larvae. Some species in the family ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1991
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...
