Victorian Funnel-web Spider
Hadronyche modesta
Family: Hexathelidae ID: Simon, 1891
Habitat and Biology
Although these spiders are related to the Sydney funnel-web
spider, they have not been implicated in any fatalities or serious envenomations.
In Melbourne, they are only known from the outskirts in the Dandenong Ranges
area. Female and male habits and biology are similar to the trap-door spider.
Females remain in or around their silk-lined burrow. During late summer and
autumn, males wander in search of females and may enter into buildings. Funnel-web
spiders use what are known as 'trip-wires' to catch their prey. These trip-wires
are strands of silk radiating from the burrow entrance. At night, the spider
sits inside the entrance with its legs touching the silken strands. When it
feels the vibrations of an insect tripping the wires the spider pounces on the
prey.
Colour
Male: Similar to female, though cephalothorax and legs
often with a polished lustre.
Female: Cephalothorax and legs shining black, abdomen
dark brown to black.
Form
Similar in form to Trap-door spider except generally smaller
in overall body size and darker in colour.
Body Length
Male: 20mm
Female: 30mm
Web type
Several strands of silk radiate from around the entrance
of the burrow.
Bite
Despite being a relative of the Sydney funnel-web spider, the
venom is only known to cause general symptoms such as headaches and nausea.
