Jumping Spider Species and Evolution
Jumping spiders belong to the Salticidae family, one of the most diverse spider groups, with over 5,000 described species in nature. They are worldwide distributed and are only absent from Antarctica.
From an evolutionary point of view, their most distinguishing characteristic is that they possess four pairs of eyes and exceptional visual acuity. However, the medial two eyes give jumping spiders this great vision. These medial eyes possess six muscles, allowing precise eye movements, and they have also evolved trichromatic colour vision.
Jumping spiders’ exceptional eyesight has led to diverse behavioural adaptations. Many species mimic ants, beetles, or mantids and display vibrant colours using structural and pigmented scales. Their prey capture strategies vary widely, from visual stalking and web use to ambushing and prey specialisation. Courtship and agonistic fighting displays are both visual and vibratory. The development of their high-resolution vision likely played a role in the evolutionary success of these spiders.
Jumping spiders belong to a major spider lineage clade, characterised by losing web-building abilities. Their remarkable visual system appears to have driven their evolutionary trajectory. While other spiders exhibit retina movement, only salticids possess four-tiered retinae, providing great visual resolution.
Distribution of Jumping Spiders
Jumping spiders are found worldwide, and every region has different species. The only area where jumping spiders have not been recorded is Antarctica.
North America, for example, hosts a diverse jumping spider fauna, particularly in the southwestern United States and northern Mexico, where over 150 species are known.
While many genera evolved locally, others, such as Salticus and Pellenes, likely have Eurasian origins. The evolution of genera such as Pelegrina, Phidippus, and Habronattus reflects ancient and recent dispersal patterns. The Hawaiian genus Havaika, closely related to Pellenes and Habronattus, suggests a complex biogeographic history involving long-distance dispersal. The southwestern U.S. fauna represents a dynamic system shaped by historical and ecological factors.
There are 36 species of jumping spiders in the UK, mostly found in coastal regions or the south of the country. Evarcha Falcata, Eliophanus Heliophanus Cupreus, and Flavipes are among the most common.
How Long do Jumping Spiders Live in the Wild?
Most jumping spiders have annual or biennial life cycles. They typically complete their development and reproduction within one or two years. However, some species have been recorded living longer in controlled environments.
Yllenus Arenarius, a species of jumping spider studied in natural conditions, has been observed living up to:
- 720 days (about 2 years) for males
- 750–770 days (just over 2 years) for females
These findings make it one of the longest-lived salticid spiders reported in the wild. In contrast, another species, Sitticus fasciger, has lived over 800 days in captivity but only up to 428 days in the field.
These findings show that controlled environments can sometimes extend lifespans by reducing predation risks and providing a steady food supply.
How long do Jumping Spiders Live In Captivity
Jumping spiders live 1 to 3 years in captivity, though some individuals may exceed this range and live up to 4 years.
Various factors influence the average lifespan of jumping spiders, including species-specific lifespans and the environmental conditions they experience.
Factors Affecting Jumping Spider Lifespan
Several factors influence how long a jumping spider lives:
- Species Differences – Some species naturally have longer lifespans due to their genetic makeup and ecological adaptations.
- Environmental Conditions – Spiders living in harsh climates may have shorter lives due to extreme weather, food scarcity, or predation.
- Food Availability – Spiders with consistent access to prey may develop steadily and live longer, while those facing food shortages may experience slower growth and a shorter lifespan.
- Predation and Threats – Natural predators, including birds, lizards, and other spiders, reduce survival rates in the wild.
- Developmental Rate – Spiders in cooler or resource-limited environments may grow and mature more slowly, sometimes leading to an extended life cycle.
Lifespan Variations by Species
Among the diverse species of jumping spiders, variations in lifespan are notable and often reflect specific adaptations to their environments.
Most jumping spider species average around a year in the wild due to challenges such as predation and resource competition. However, in captivity, some captive jumping spiders can surpass the lifespan norms, occasionally reaching up to 4 years with ideal care.
Such variations emphasise the interplay between species-specific traits and the environments they inhabit, whether captive or wild, affecting their overall lifespan.
These insights into species-specific lifespans illustrate the dynamic nature of jumping spider ecology.
How Long do Regal Jumping Spiders Live in Captivity?
Regal Jumping Spiders (Phidippus regius) can live up to 2-3 years with favourable conditions, including stable temperature and humidity.
Factors such as diet quality and proper care practices in captivity can greatly enhance their longevity compared to their counterparts in the wild.
Captive environments that offer a controlled habitat and consistent food availability contribute to the healthy development of these arachnids and extend their lifespans.
Captive care emphasising quality nutrition and the right environmental conditions can push their longevity towards the upper end of the 2 to 3 years spectrum.
The regal jumping spider is one of the species that can live longer in captivity. In contrast, the genetics of the Zebra Jumping Spider (Salticus scenics) generally allow a shorter lifespan of 1-2 years. This variance is largely due to species-specific characteristics and the quality of care needed.
Regular health monitoring is vital in identifying and addressing potential health issues early, supporting longer lifespans. Stress reduction through careful handling also significantly ensures jumping spiders remain healthy, ultimately contributing to an extended lifespan.
Environmental Impact on Lifespan
Environmental factors also determine the lifespan of jumping spiders. Temperature and humidity, in particular, heavily influence their longevity.
- Maintaining a stable temperature environment between 21° and 29°C helps a jumping spider’s metabolism. Conversely, deviations from this ideal range can lead to metabolic stress.
- Humidity is another significant environmental factor, as high moisture levels are crucial for the health of jumping spiders. Inadequate moisture can cause issues with molting. The best range humidity is between 60-70%
Additionally, overfeeding can result in obesity. Responsible feeding practices are necessary to avoid this risk.
In the wild, jumping spiders face environmental stressors, including predation and resource competition, which can substantially limit their lifespan, often reducing it to about one year.
Life Cycle and Reproduction
Jumping spiders spend their early lives in protective nests before emerging to hunt. In the case of Yllenus Arenarius, its life cycle is particularly interesting:
- It has a two-year development period, meaning individuals hatch and grow for two years before reproducing.
- Mating typically occurs in autumn, with egg-laying in the following spring.
- The species exhibits low fecundity (producing fewer, but larger eggs), which suggests a reproductive strategy focused on survival rather than mass reproduction.
Additionally, some populations of Y. Arenarius appear to be split into two groups that reproduce in alternating years, reducing genetic exchange between cohorts. This unique cycle may have evolved due to environmental pressures or historical population shifts.
Reproduction plays an essential role in the lifespan of jumping spiders, with various factors influencing their longevity. The reproductive status of these arachnids can greatly impact how long they live. Anecdotal evidence indicates that infertile females may enjoy a longer lifespan compared to those who have mated. This is partly because mating behaviour can increase stress and energy expenditure, particularly in males. Male jumping spiders often face a reduced lifespan as they frequently die shortly after mating.
Environmental conditions during the mating season, such as temperature fluctuations and food availability, also can affect reproductive success.
Survival Strategies and Adaptations
Jumping spiders have evolved several adaptations to help survival:
- Building Protective Nests – Y. Arenarius constructs underground nests for moulting, egg-laying, hibernation, and shelter from extreme weather.
- Camouflage and Cryptic Behavior – Many species blend into their surroundings to avoid predators.
- Efficient Hunting Techniques – Their ability to actively hunt rather than rely on webs increases their chances of securing food.
Diet and Lifespan Connection
A well-balanced diet is fundamental for the health and longevity of jumping spiders in captivity. Their diet primarily consists of live insects, and the quality and frequency of their feeding directly correlate with their lifespan. An adult jumping spider in captivity generally requires feeding every 5-10 days. A nourished spider, evidenced by a plump abdomen, typically enjoys a longer lifespan.
However, overfeeding can lead to obesity, adversely affecting their health and longevity. Therefore, moderation is key, making it essential to maintain a balanced diet that avoids the pitfalls of excessive feeding.
Diverse nutrition is critical for these arachnids, and their diet includes smaller prey, such as wingless fruit flies and dubia roaches. This variety guarantees their nutritional needs are met, supporting a longer lifespan.
Proper feeding practices are indispensable. They prevent the risks associated with oversized prey and assure regular access to food. These practices are integral to extending the lifespan of jumping spiders in captivity.
Jumping Spiders Sleep Behaviour
Unlike mammals, spiders do not have eyelids, so they cannot physically close their eyes. However, studies suggest that jumping spiders enter a sleep-like state, suspending movement, lowering their metabolic rate, and may even experience REM-like activity. In a study by Rößler et al. (2022), young jumping spiders (Evarcha Arcuata) were observed in a suspended rest state where they curled their legs and occasionally exhibited eye-tube movements similar to REM sleep in humans.
How Long Do Jumping Spiders Sleep?
The exact sleep duration of jumping spiders varies depending on species, age, and environmental factors. However, observations suggest that they can sleep for several hours at night.
In the study by Rößler et al., juvenile jumping spiders were found to cycle through sleep-like states, with periods of stillness lasting minutes to hours. While an exact number of hours is difficult to determine for all species, it is estimated that they may sleep between 6 to 12 hours per day, mostly at night.
Sleep Patterns in Jumping Spiders
Jumping spiders are diurnal, meaning they are active during the day and rest at night. Their sleep cycles may include:
- Resting Phase – Spiders remain still for extended periods, often hanging from a silk thread or hiding in a retreat.
- REM-like Activity – In some species, eye-tube movements and leg twitches occur, similar to REM sleep in mammals.
- Interrupted Sleep – Like many arthropods, their rest can be disturbed by external stimuli such as light, vibrations, or the presence of prey or predators.
Why Do Jumping Spiders Sleep?
Sleep is essential for most animals’ energy conservation, neural processing, and overall health. For jumping spiders, sleep likely plays a role in:
- Energy Conservation – Resting at night helps them recover from the energy-intensive hunting and stalking behaviours they engage in during the day.
- Memory and Learning – Their advanced visual system and complex hunting strategies suggest they may require sleep to process information and improve cognitive function.
- Survival and Camouflage – Many species sleep while hanging from silk threads in hidden locations, reducing their risk of predation.
Conclusion
Jumping spiders are remarkable creatures with diverse lifespans influenced by species, environment, and care conditions.
Most jumping spiders live in the wild for about one to two years, though some species can survive longer under optimal conditions. In captivity, with stable temperatures, proper humidity, and a well-balanced diet, they can live up to three or even four years.
Predation, food availability, and reproductive behaviours significantly impact their lifespan. Due to the energy demands of mating, males generally have shorter lifespans, while infertile females may live longer. Additionally, jumping spiders display sleep-like behaviours, indicating their complex physiological needs.
Understanding these factors allows enthusiasts and researchers to appreciate and better care for these fascinating arachnids, whether in nature or captivity.
