Parapoynx fluctuosalis is a butterfly from the family of Crambiden ( Crambidae ).

features

The moths reach a wingspan of 14 to 18 millimeters for the males and 18 to 23 millimeters for the females. The forewings are white and have a yellow-brown, partially resolved proximal line. The discocellular spot is small and black. The distal line is yellow-brown and has a more or less strong brown border. Sometimes it is completely brown and strongly curved towards the inner edge. The submargin line is yellow-brown and has a brown border. It is partly completely brown. The submarginal area is bordered in brown on the inside. The outer half is yellow-brown, the inner half is white. The hind wings are white and have a brown proximal line that is strongly shifted towards the base of the wing. The distal line is brown. The submargin line is yellow-brown and brown-edged or completely brown. The submarginal area has a brown border on the inside, the inner half is white and the outer half is yellow-brown.

The nominotypical specimens have on average a slightly larger wingspan (males 18 millimeters; females 23 millimeters) than the ssp. linealis and are usually more strongly drawn.

In the males, Uncus and Gnathos are strong. The apical part of the gnathos is not dentate. The blades are more or less oval and wavy on the ventral edge. The Juxta is narrow. The ejaculatorious bulb opens at the base of the phallus and is slightly dilated distally. The shape of the valves differs between the two subspecies. At P. f. fluctuosalis , the ventral margin is wavy, in P. f. linealis, on the other hand, is straight.

In females is Oviscapter slim and has basal slightly dilated apophyses. The colliculum is strong. The ductus bursae is long and continuously widens towards the corpus bursae . The signum consists of two oval, heavily roughened areas that extend in the form of two weak and narrow ridges in the direction of the ductus bursae.

The eggs are oval, flat and yellowish in color.

The doll's legs are longer than the abdomen .

distribution

Parapoynx fluctuosalis has a pantropical distribution area and occurs in southern Europe to the north to the south of Portugal and Spain as well as on Sardinia . The species was introduced to 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 distribution area, moths can be found throughout the year. In Europe they are mainly found in September. The young caterpillars have no tracheal gills , on the back of the last abdominal segment there is a pair of long bristles. Older caterpillars have bundled tracheal gills. They live in a housing made of plant parts. The host plants include rice ( Oryza sativa ) and various aquatic sweet grasses (Poaceae). The caterpillars pupate within the leaf housing in a cocoon .

Systematics

There are two known subspecies that cannot always be clearly distinguished. P. f. fluctuosalis colonizes Africa and southern Europe. The subspecies P. f. linealis is native to the subtropical and tropical regions of Asia, Australia, the Pacific Islands, and Central and South America.
