They typically live in rotting holes in the bark and build silk trip wires outside the holes to alert themselves to prey, according to the Australian Museum. While most funnel spiders live on the ground, a few species on the eastern coast of Australia live in wet forest trees. These spiders usually eat insects or small vertebrates like lizards or frogs. According to the Museum Victoria, the entrance to the burrow is surrounded by irregular strands of silk, which act as trip wires, alerting the spider hiding in the burrow that prey is present. Males only live for a few months after mating, but females can live for several years (some reports say up to 20).Īustralian funnel spiders pick moist and sheltered places to build their burrows, like under rocks or logs or in shrubbery. Once they hatch, the young spiders stay in the burrow until they are big enough to leave. They also assume this rearing position when threatened.Īccording to the Queensland Museum, the female spider lays her eggs in her burrow. To mate, they rear up on their hind legs and press their bodies together, according to the Australian Museum. The two spiders spar until the female accepts the male. They prefer humid climates, as they are susceptible to drying out, according to the Australian Museum.ĭuring the summer, males leave their burrows and go wandering for females. These mostly nocturnal spiders can be found at any time of the year. Males are smaller than females.Īccording to Bills, these spiders typically live in burrows. long spinnerets.” They are distinguished by their shiny carapace (hard covering over the front of the body), which is lightly haired. Bills noted that they are mygalomorphs, which means they have “distinct fangs and. “This group contains some spiders of medical significance in their native Australia,” Bills said.While most species are not dangerous to humans, the Sydney funnel spider and the tree-dwelling venomous biters have garnered deadly reputations.Īccording to the World Heritage Encyclopedia, these funnel spiders are medium-sized, getting up to about 1 to 2 inches (2.54 to 5 centimeters), and are typically black or brown. Both are often included on lists of the most deadly spiders in the world, according to the Commonwealth Scientific and Industrial Research Organization (CSIRO). Two well-known species of Hexathelidae are the Sydney funnel spider and the northern tree funnel spider. Hexathelid spiders live in Australia, and their funnel webs are really burrows lined with silk. Hexathelidae: Dangerous Australian funnel spiders These spiders typically eat insects, though they have been known to eat other spiders. According to Iowa State University's, webs are also often seen in the corners of porches or in the cracks of shingles (anywhere there is a crevice for them to build a funnel web inside). Residents of grassy areas will recognize the funnel webs scattered in the grass during the summer and early fall. Dead female spiders are often found clinging to the egg sac, according to Herbert Levi and his co-authors in " Spiders and Their Kin" (St. ![]() Agelenids lay eggs in the fall, and the spiderlings hatch in the spring. They typically lay several egg sacs and cover them in webbing for protection. Males spend most of their time wandering in search of a mate, though they usually die after they mate a few times. ![]() ![]() In warmer places, they can live for two years. They are known to flee from light and “many are very fast runners,” Bills said.Īccording to BioKids, they typically live for less than a year, dying in the cold weather. Like most species of spiders, funnel weavers are nocturnal. “They have eight eyes,” Bills said, arranged in two rows. According to the University of Michigan’s BioKids, these species are usually grey or brown, with spots on their backs and banded legs. Agelenids are medium-sized for arachnids - about 4 to 20 millimeters long (up to three-quarters of an inch).
