Scientific Name: Urodacus manicatus
That all species of scorpion glow under a black UV (ultraviolet) light? A thin transparent film (hyaline) in the outmost layer (cuticle) of their exoskeleton contains a protein that fluoresces. They glow green-blue or yellow-green. Newly moulted scorpions don't fluoresce. As the cuticle hardens, it glows more. The hyaline skin toughens into an incredible substance.
Black Rock Scorpions are usually dark brown, sometimes black with a body length of around 55mm, in a typical scorpion stance. They are a relatively long lived species, females can take 2 years to reach maturity and can live for a further 8 years.
These scorpions are native to Australia. They live in burrows under logs and rocks all over Victoria, the ACT and NSW as well as in South Australia and Queensland.
The black rock scorpion survives on a diet of other invertebrates such as cockroaches, beetles, millipedes, centipedes, spiders and occasionally earthworms. They also prey on their own kind, 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 females then perform a mating dance above the spermatophore, with the female being wrestled into position over it in oder 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.
