Identification
Physical Characteristics
Size: Adult males and females typically range from 4-5mm in body length.
Coloration: Males possess a stunning, iridescent abdominal flap with vibrant patterns of metallic blues, reds, oranges, and yellows against a dark background, resembling a peacock's tail. Females are cryptic, predominantly brown and grey with mottled patterns for camouflage.
Key Features: The male's unique, colourful, and extendable abdominal fan is the primary distinguishing feature. The specific pattern of this fan distinguishes M. mungaich from other peacock spider species.
Biology & Lifecycle
Development & Reproduction
Reproduction Rate: Females likely produce one or two egg sacs per breeding season, with each sac containing a variable number of eggs. The breeding season is synchronized with warmer months when prey is abundant.
Lifecycle Details
Egg Stage
After mating, the female lays a clutch of eggs within a protective silk sac, often hidden in leaf litter, under bark, or within a folded leaf. The sac is guarded by the female until the spiderlings hatch. Egg development is dependent on temperature and humidity, typically taking a few weeks.
Larval Stage
Technically, spiders have a post-embryonic or 'spiderling' stage rather than a larval stage. Upon hatching, spiderlings emerge from the egg sac. They are miniature versions of the adults but lack the male's colouration. They are independent from hatching, dispersing to find their own food and territory.
Pupal Stage
Spiders do not undergo a pupal stage. They grow by moulting (ecdysis), shedding their exoskeleton periodically to increase in size. This process occurs multiple times before reaching maturity.
Adult Stage
Adulthood is reached after the final moult, typically in spring. The adult lifespan is approximately one year. Once mature, males dedicate their energy to courtship displays to attract females, while females focus on hunting to fuel egg production.
Reproduction Rate
Females likely produce one or two egg sacs per breeding season, with each sac containing a variable number of eggs. The breeding season is synchronized with warmer months when prey is abundant.
Generations Per Year
Typically one generation per year. The spiders that hatch in late summer or autumn will overwinter as juveniles and mature the following spring.
Development Time
The complete development from egg to mature adult takes several months, influenced heavily by environmental conditions like temperature and food availability.
Seasonal Cycle
The annual cycle begins with males maturing in spring (September/October) and commencing their courtship displays. Mating occurs, and females lay eggs. Spiderlings hatch and grow through summer and autumn, then overwinter as sub-adults before maturing the next spring.
Environmental Factors
Lifecycle timing is critically linked to the photoperiod and temperature cues of spring. The availability of small insects for food and suitable Banksia or other low-lying vegetation for habitat are crucial for survival and reproduction.

Detection & Signs
Visual Signs
- This species does not 'infest' properties. Signs of presence are simply sightings of the spiders themselves.
- Spotting a male performing his courtship dance on a leaf or plant.
- Seeing a small, fast-moving spider that jumps when disturbed.
- Finding a female guarding a small, white egg sac within a folded leaf.
- Their presence is an indicator of a healthy garden ecosystem, not a pest problem.
Physical Evidence
- The only physical evidence is the spider itself or a discarded egg sac. They do not leave behind webs, droppings, or damage.
- You might find a tiny, shed exoskeleton (moult) on a leaf, but it would be very difficult to spot.
Behavioral Signs
- Observing the characteristic stop-start, jerky movements and sudden jumps of a hunting jumping spider.
- Witnessing the unique courtship dance of a male is the most definitive behavioural sign.
Seasonal Indicators
- Presence is most noticeable in spring and early summer (September to December) when males are actively courting.
- Juveniles may be present in autumn but are much smaller and harder to see.
Early Warning Signals
- Not applicable in a pest context. An 'early warning' of their presence is simply the first sighting, which should be considered a positive event for garden biodiversity.
Prevention
Sanitation Measures
- No sanitation measures are necessary to prevent this species. They are not attracted to human food, waste, or clutter.
- Maintaining a garden with native plants and leaf litter will encourage their presence, which is ecologically beneficial.
- They are part of a clean, healthy garden environment.
Exclusion Methods
- If their presence indoors is unwanted, the focus should be on general pest exclusion.
- Ensure insect screens on windows and doors are in good repair.
- Seal cracks and crevices in the building exterior, which also prevents actual pests.
- They may occasionally wander inside by accident, but they do not seek to live indoors.
- No specific exclusion methods are needed for this species.
Landscaping Tips
- To encourage them, plant native species like Banksias, grevilleas, and other low-growing shrubs.
- Allow some leaf litter to accumulate under plants to provide shelter and a hunting ground.
- Avoid using broad-spectrum pesticides, which will kill these beneficial spiders and their insect prey.
- A diverse garden with a variety of plants will support a healthier ecosystem and more of these spiders.
Monitoring Strategies
- Monitoring is done for enjoyment and observation, not control.
- Carefully inspect low-lying vegetation and leaf litter on sunny days.
- Look for the quick, jumping movements that are characteristic of this family.
- No traps or professional monitoring are ever needed.
Environmental Modification
- No environmental modification is needed for prevention. To see them, one must preserve their natural habitat. Habitat destruction is the biggest threat to them, so preserving bushland and native gardens is the best 'modification' one can do.

Frequently Asked Questions
What makes the Banksia Peacock Spider different from other spider species?
The Banksia Peacock Spider (*Maratus mungaich*) stands out due to the extreme visual differences between sexes and its unique behaviour. The most defining characteristic is the male's abdominal flap, which features breathtaking iridescent patterns of blue, red, and yellow. This isn't just for show; it's a critical component of one of the most complex courtship rituals in the arachnid world. The male performs a vibrant, energetic dance, waving his legs and vibrating this fan to impress a female. This behaviour is a stark contrast to the passive hunting strategies of web-building spiders. Furthermore, they are part of the Salticidae family (jumping spiders), possessing exceptional, colour vision from their large forward-facing eyes, which they use to hunt actively like tiny cats, stalking and pouncing on their prey rather than trapping it. Unlike many spiders that are feared, they are completely harmless to humans, very small (4-5mm), and considered beneficial predators in their ecosystem.
Is the Banksia Peacock Spider dangerous to humans?
No, the Banksia Peacock Spider is not dangerous to humans in any way. It is considered completely harmless. Firstly, its fangs are tiny and designed to subdue very small insect prey, making it physically incapable of delivering a significant bite to a human. Secondly, its venom is specialized for small invertebrates and is not medically significant to people. There has never been a recorded case of this spider causing any medical issues. They are also non-aggressive and will always flee if approached. An encounter with one is a rare privilege, not a threat. There is no risk of allergies, disease transmission, or any other health impact. These spiders pose zero risk to children, pets, or adults.
How can I get rid of Banksia Peacock Spiders?
There is no reason to 'get rid of' Banksia Peacock Spiders. They are not pests and their presence is a positive indicator of a healthy garden environment. They do not damage property, infest homes, or harm humans. Killing them would be eliminating a beneficial predator that helps control small nuisance insects. If you find one inside your home by accident, it should not be killed. The best and only recommended course of action is gentle relocation. You can easily do this by placing a small container or cup over the spider, sliding a piece of paper underneath to trap it, and then releasing it outside onto a plant. No chemical treatments or traps are ever necessary or appropriate for this species.
How can I prevent Banksia Peacock Spiders from coming into my house?
Banksia Peacock Spiders do not want to be in your house. Any appearance indoors is purely accidental. The most effective way to prevent them, along with other insects and actual pests, is through physical exclusion. This involves ensuring that your window and door screens are intact and free of holes. You should also seal any small cracks or gaps around window frames, door frames, and where utility lines enter your home. However, no specific prevention measures are needed for this species. They are not attracted to indoor environments. The best 'prevention' is to appreciate them in their natural habitat: your garden, where they contribute positively to the ecosystem.
When are Banksia Peacock Spiders most active during the year?
The Banksia Peacock Spider is most active and visible during the Australian spring, from roughly September to November. This is their breeding season. During this time, the males have reached maturity and spend their days performing their famous courtship dances to attract females. This activity is heavily dependent on the weather; they are diurnal and you will most likely see them on warm, sunny days. In the summer, you might see females guarding their egg sacs or newly hatched spiderlings. During autumn, the juveniles are growing, and by winter, they become largely inactive, taking shelter in leaf litter to survive the cold. So, if you want to spot one, the best time to look is on a bright spring day in the heathlands of Southwestern Australia.
