Epeira appensa |
Argiope appensa is a spider that occurs on several islands in the Western Pacific Ocean. It has been introduced to Hawai'i, and is found on Taiwan and New Guinea. It inhabits a wide variety of habitats, from coasts to forests.

[edit] Description
Females reach a body length of up to 7cm and are strikingly black and yellow, while the brown males reach only about 2cm. [1]
On Guam, where A. appensa is ubiquitous, it is frequently visited by Argyrodes argentatus. Locals there refer to A. appensa as banana spiders. Following the introduction of the brown tree snake and the subsequent extinction or near-extinction of many of the island's small birds, spider populations on Guam exploded decreasing predation and competition. A. appensa is almost certainly one of the large species which were encountered there in vast numbers, much to his horror, by nature writer David Quammen (who is extremely arachnophobic) during his trip doing background research for the book The Song of the Dodo, as he vividly recalls therein.
[edit] Trivia
This species was used in episode "Exposé" of Lost, which is filmed on location in Hawai'i. It is there named Latrodectus regina, a fictional species of widow spider, in the family Theridiidae. The "males" that run for the female are also females, as the males are much smaller.
