List Of Hoverfly Species Of Great Britain
The following is a list of hoverfly (Syrphidae) species recorded in Great Britain. Alan Stubbs and Steven Falk, in their 1983 work ''British Hoverflies'', divided the family into subfamilies and tribes. These subdivisions are now believed to be, to some extent, artificial groupings, not reflecting the evolutionary relationships within the family, so in need of revision. As no replacement system is yet in place, though, these groupings are retained in this list. The six unnamed species listed in Stubbs and Falk (1983) are not included below. Subfamily Syrphinae Tribe Bacchini (incorporating Melanostomatini) ;''Baccha'' :* '' Baccha elongata'' (syn. ''B. obscuripennis'') ;''Melanostoma'' :* '' Melanostoma dubium'' :* '' Melanostoma mellinum'' :* '' Melanostoma scalare'' ;''Platycheirus'' :*Subgenus ''Pachysphyria'' :** '' Platycheirus ambiguus'' :*Subgenus ''Platycheirus'' :** ''Platycheirus albimanus'' :**''Platycheirus amplus'' :** '' Platycheirus angustatus'' :** ''Platyc ...

Male Hoverfly With Thin Abdomen
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of ...
