Parapoynx fluctuosalis
Parapoynx fluctuosalis is a butterfly of the family of Crambiden ( Crambidae ).
Features
The moths reach a wingspan of 14-18 mm in males and 18-23 mm in females. The forewings are white and have a yellow-brown, partially resolved Proximallinie. The Diskozellularfleck is small and black. The Distallinie is edged with yellow-brown and more or less strong brown. Sometimes it is also completely curved brown and strong towards the inner edge. The Submarginallinie is edged with yellow-brown and brown. It is partially completely brown. The Submarginalbereich is inside edged brown. The outer half is yellow-brown, the inner half is white. The hind wings are white and have a brown Proximallinie, which is strongly shifted to the wing base. The Distallinie is brown. The Submarginallinie is yellow-brown and brown edged or completely brown. The Submarginalbereich is inside margins brown, the inner half is white and yellow brown, the outer half.
The nominotypischen copies on average a slightly larger wingspan ( males 18 millimeters; females 23 mm) than the ssp. linealis and are mostly drawn strong.
In the male uncus and Gnathos are strong. The apical part of the Gnathos is not perforated. The Valven are more or less oval and wavy on the ventral margin. The juxtaposition is narrow. At the base of the phallus opens the eyeball ejaculatorious, distally slightly dilated. The shape of the blades is different between the two subspecies. In P. f fluctuosalis the ventral margin is curled, in P. f linealis against it straight.
In females, the Oviscapter is slim and has slightly dilated basal apophyses. The Colliculum is strong. The ductus bursae is long and widens continuously in the direction of the corpus bursae. The Signum consists of two oval, strongly roughened areas ranging in the form of two weak and narrow ridges in the direction of ductus bursae.
The eggs are oval, flat and yellowish.
In the doll's legs are longer than the abdomen.
Dissemination
Parapoynx fluctuosalis has a pantropisches distribution area and comes in southern Europe to the north to the south of Portugal and Spain and Sardinia before. The species was introduced into England, where it was found in greenhouses for tropical aquatic plants. The species is widespread and is also found in Africa, India, Sri Lanka, China, Japan, Malaysia, Taiwan, Guam, Hawaii, Australia, Central and South America.
Biology
In the tropical areas of the circulation area moth can be found throughout the year. In Europe they are found mainly in September. The young caterpillars do not have tracheal gills on the back of the last abdominal segment there is a pair of long bristles. Older caterpillars have bundle -like branched tracheal gills. They live in a housing made of plant parts. The host plants include rice ( Oryza sativa ) and various aquatic grasses ( Poaceae ). The caterpillars pupate within the blade enclosure in a cocoon.
System
There are two subspecies, which can not always be clearly distinguished. P. f fluctuosalis colonized Africa and southern Europe. The subspecies P. f linealis is native to the subtropical and tropical regions of Asia, Australia, the Pacific islands and in Central and South America.
