Celaenia Excavata
''Celaenia excavata'', the bird dropping spider of Australia and New Zealand, derives its name from mimicking bird droppings to avoid predators, mainly birds. However, there are other species of spider that resemble bird droppings, for example species of '' Mastophora'' (a bolas spider). Habitat and appearance The males are much smaller than the females, about 2.5 mm as opposed to 12 mm. The females have up to 13 egg sacs, with about 200 eggs each, strung together with strong threads. Their toxicity is unknown, but may be able to cause mild illness in humans. ''Celaenia excavata'' is found throughout large parts of eastern and southern Australia and have also been recorded in central Australia; they are also seen in suburban gardens. The egg sacs of the bird-dropping spider are large, marbled brown colored spheres, each about 12 mm in diameter and containing over 200 eggs. Up to 13 sacs are silked together in a group, beneath which the spider may be found awaiting pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Of New Zealand
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions. The New Zealand spider with the largest leg span is the Nelson cave spider ('' Spelungula cavernicola''), with a leg span of up to and a body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites. The flat huntsman spider ('' Delena cancerides''), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.Rowell and Avilés (1995).
