Brettus
''Brettus'' is a genus of jumping spiders. Its six described species are found in southern Asia from India to China and Sulawesi, with a single species endemic to Madagascar. Two species in this genus, ''B. celebensis'' and ''B. madagascarensis'', were originally described as members of the genus ''Macopaeus''. According to Thorell, the genus name is taken from Greek mythology. Brettos (Βρεττος) was a son of Heracles (appears at Stephanus of Byzantium). Diet and behaviour At least 2 species, ''Brettus cingulatus'' and ''Brettus adonis'', feed on other spiders. Taking advantage of their ability to not adhere to any kind of spider silk, they practise aggressive mimicry and pluck upon the webs of web-building spiders to lure them over to the ''Brettus'' at the edge of the web, where they capture/stab their victim. These two spider species also prefer web-building spiders to insects as prey. They are in these regards similar to the other Spartaeinae jumping spiders of gen ...

Brettus Adonis
''Brettus adonis'', is a species of spider of the genus ''Brettus''. It is endemic to Sri Lanka. Diet and behaviour ''Brettus adonis'' preys upon other spiders, mainly web-building ones. Members of this species do not stick to any kind of spider silk, and will invade the webs of other spiders to feed on them. To capture a web-building spider, they typically pluck upon the silken strings at the edge of the web with their pedipalps, varying how they pluck until an effective rhythm is found. Then, they repeat this manner of plucking and lure the spider over(aggressive mimicry Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host. Zoologists have repeatedly compared t ...), capturing or stabbing their prey in a lunging attack.

Brettus Cingulatus
''Brettus cingulatus'' is a species of jumping spider of the genus ''Brettus''. It is found in Myanmar and India. The species was first described in 1895 from a single specimen. The female was originally misidentified as another species, ''B. albolimbatus''. Males and females look very different due to sexual dimorphism. Only in 2017 was the species rediscovered near Mumbai, India, far away from its original discovery in Myanmar. The epithet "cingulatus" means "wearing a belt" in Latin, "albolimbatus" refers to white limbs. Diet and behaviour This spider preys upon other spiders. To capture web-building spiders, the typical strategy is to stand at the edge of the web and pluck upon the silken strings with its pedipalps, trying out numerous patterns/rhythms until an effective one is found, then to lunge and capture/stab the spider when it gets lured over(aggressive mimicry). ''Brettus cingulatus'' does not adhere to spider silk and can walk on webs with ease, but usually does not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macopaeus
''Macopaeus'' is a genus of jumping spiders endemic to Madagascar. It contains only one species, ''Macopaeus spinosus''. Two other species ('' M. celebensis'' Merian, 1911 and '' M. madagascarensis'' Peckham & Peckham, 1903) were described in this genus in the early 20th century. However, these were transferred to the genus ''Brettus ''Brettus'' is a genus of jumping spiders.

Heracles
Heracles ( ; grc-gre, Ἡρακλῆς, , glory/fame of Hera), born Alcaeus (, ''Alkaios'') or Alcides (, ''Alkeidēs''), was a divine hero in Greek mythology, the son of Zeus and Alcmene, and the foster son of Amphitryon.By his adoptive descent through Amphitryon, Heracles receives the epithet Alcides, as "of the line of Alcaeus", father of Amphitryon. Amphitryon's own, mortal son was Iphicles. He was a great-grandson and half-brother (as they are both sired by the god Zeus) of Perseus, and similarly a half-brother of Dionysus. He was the greatest of the Greek heroes, the ancestor of royal clans who claimed to be Heracleidae (), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. The Romans adopted the Greek version of his life and works essentially unchanged, but added anecdotal detail of their own, so ...

Salticidae
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

Spartaeinae
The Spartaeinae are a subfamily of the spider family Salticidae (jumping spiders). The subfamily was established by Fred R. Wanless in 1984 to include the groups Boetheae, Cocaleae, Lineae, Codeteae and Cyrbeae, which in turn were defined by Eugène Simon. The Spartaeinae are palaeotropical, with an exceptional diversity in the Malaysian and Indonesian archipelagos. They are unusual salticids that are considered basal to the phylogenetic tree of jumping spiders. Like the Lyssomaninae they lack many derived features that the Salticinae possess. Spartaeinae usually have large posterior median eyes. However, these were reduced in the genera ''Cyrba'', ''Gelotia'' and ''Wanlessia''. Genera In 2015, Spartaeinae was divided into three tribes with 29 genera. One has been added since. Tribe Cocalodini * '' Allococalodes'' Wanless, 1982 * '' Cocalodes'' Pocock, 1897 * '' Cucudeta'' Maddison, 2009 * '' Depreissia'' Lessert, 1942 * '' Tabuina'' Maddison, 2009 * '' Yamangalea'' Madd ...

Cyrba
''Cyrba'' is a genus of spiders in the family Salticidae (jumping spiders). The genus was erected by Hippolyte Lucas in 1846. Description ''Cyrba'' spiders are small to medium size spiders that are usually brightly colored. Their cephalothorax is long and moderately high. The eyes are lateral. The abdomen is long with bright colorful patterns. Their legs are thin and slender. The genus has been described as primitive because of their pervasive use of webs, large posterior median eyes, and the secretory organs on the femora of males. These characteristics were lost by advanced salticids. The genus are also almost wholly dependent on their vision. The primary mating season for the spider ''C. algerina'' is May. Juveniles emerge in July, grow to about half the adult size by winter, and then grow to adult size in the spring of the following year. The genus is commonly found on very rocky ground under rocks, or less often walking around on the ground or on the tops of rocks. Sil ...

Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...
