Spiders of Nosara

Golden Silk Orb-Weaver

Golden silk orb-weaver spiders, also known as giant wood spiders, or banana spiders, consist of numerous different sub-genre species. All of these inhabit the warmer regions of the planet, particularly the tropics, where they are famed for the stunning and intricate webs they weave.

They’re also known for their spectacular coloring and markings, varying from black, brown, and reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the abdomen. These colors, some of which signal venom, often serve to repel any would-be predators.

Golden orb-weavers reach sizes of 5 cm in females, with males being usually significantly smaller. They inhabit dry open forest and woodlands, coastal sand dune shrubland and mangrove habitats. Here is where they weave suspended, sticky, wheel-shaped orb webs between trees and flora where insects are likely to become entrapped.

Costa Rican Tiger Rump

This spider, which is native to Costa Rica, takes its name from the coloring and stripes daubing it’s lower section. Although relatively small for a tarantula, it is still one of the larger members of its genus, with a maximum leg span of up to 12 cm. These are among the more mobile tarantulas, and spend all their time spinning and weaving webs or burrowing.

They are fast growers, and have a voracious appetite for crickets, roaches, and other bugs.

Costa Rican Zebra Tarantula

Zebra tarantulas are deep-burrowing spiders that inhabit open, semiarid scrublands. They choose deep burrows to avoid the highest daytime temperatures, and because they retain humidity. Conversely as night sets in, and temperatures drop, they come out into the open in search of food, which includes grasshoppers, bugs, roaches, and crickets. These spiders leg span can grow as long as 13cm. Whereas males tend to die at around 5 years, females may live as long as twenty years. Although usually black with white stripes on the legs, they are also known to be brown. Costa Rican Zebra tarantulas inhabit Costa Rica, Honduras, Nicaragua, and Guatemala.
