Forest Scorpion.

 

Forest Scorpions are a common arachnids found in rocky outcrops throughout the Strathbogie Ranges.

 They nest under logs and sheets of rocks. Scorpions are mostly nocturnal but they can be active during the day, especially during prolonged wet weather. Feeding mainly on arthropods such as beetles, cockroaches, spiders, slaters, centipedes and millipedes, they are “lie-in-wait” ambushers that forage at or in the vicinity of the burrow entrance . Ground vibrations caused by moving prey are sensed both by slit-like tarsal sensory organs on the scorpion’s legs and vibration sensitive tarsal hairs. The clawed grasping pedipalps are used to hold the prey while the scorpion stings or crushes it. The scorpion digests its prey by pouring digestive juices onto the prey and breaking it up with its jaws. The hard outer body casings are discarded. The main predators of scorpions are carnivorous marsupials, rodents, lizards, nocturnal birds, centipedes and other scorpions.

Males and females find each other by vibration, scent and touch. During mating, the sensory pectines under the body are used to find a suitable place for the male to deposit his sperm parcel – the spermatophore. The male and female then perform a mating dance above the spermatophore, with the female being wrestled into position over it in order to draw it up into her genital pore. The fertilised eggs develop inside her body, and she then gives birth to live young. She carries the pale young scorpions on her back for the first few days or weeks, until they are strong enough to become independent. The young then disperse to find food and shelter. Scorpions take a long time to reach maturity, moulting frequently (up to five or six times over two to six years) in order to grow, and may live for two to ten years. Some have been recorded as living up to 25 years

Australian scorpions can give a painful sting but are not considered dangerous. First aid for a sting is to apply a cold pack and to seek medical aid if pain persists.
