Plexippus paykulli Savigny & Audoin, 1825 ♂
Common names: Pantropical jumper [En], Gobe mouche (Réunion) [Fr]
Küçükbahçe, İZMİR ● Turkey
Description: This species is robust, with a high carapace. The males are 9 to11 mm in length, while the females are 9 to12 mm. Males are distinctly black and white striped, with a light central stripe bordered by dark stripes. A pair of white spots occurs near the posterior tip of the abdomen. The male's carapace is marked with a central white stripe and a white stripe on each side, which curve up, around, and between the anterior eyes. The central white stripe also continues between the anterior eyes, so that the face presents three white stripes on a black background.
The female is brown: the carapace is darker, especially the ocular area, with a dull orange median stripe on the thoracic slope. The abdomen has two short black stripes on the posterior half, each containing two white spots, and a tan stripe down the middle with some darker chevrons within. As in most jumping spiders, the immatures resemble the adult female, although sub-adult males have more resemblance to adult males both in color pattern and in their swollen palpi.
Biology : Adults and immatures feed on a wide variety of arthropod prey, including flies, moths, smaller spiders, and flying ants. The eggsac is made by the female in a sheltered area, between or under boards, under eaves, or in suitably-sized crevices. The eggsac is 2.5 to 3.5 cm in diameter, and the female stays inside to guard a lenticular silken case about 9 mm in diameter containing 35 to 60 eggs. Spiderlings emerge and disperse between three and four weeks after the eggs are laid.
This spider does not spin a web but builds a silken retreat in an elevated position such as the edge of the ceiling from which it makes hunting forays. It has very acute eyesight and approaches its target prey stealthily, leaping on it when close enough to do so. Prey species that have been recorded as being part of the diet include Diptera, Homoptera, Hymenoptera, Lepidoptera, Odonata, Orthoptera and Aranea. They are able to successfully kill prey twice their own size. Large arthropods are injected with venom but are usually overpowered by brute strength before the venom has immobilized them.
Habitat: Plexippus paykulli is generally found living in and around man-made structures, in particular inside buildings, although it has also been recorded from citrus groves and cotton fields.
Distribution: Native to south east Asia but has spread to other parts of the world. It is cosmopolite in warm areas.
