Mating takes place in the spring and summer. Shortly after, the eggs are laid. After they hatch in the summer, the young spiderlings remain with the mother for several molts. Most jumping spiders molt five or six times before becoming an adult. The young spiders reach independence after about a month and disperse. Growth varies depending on the amount of food the developing spider consumes. (Guarisco, et al., 2001)
Most males of the genus Habronattus perform elaborate courtship behaviors prior to mating. Females, even virgin females, are highly resistant to male courtship, which may indicate that there is a physiological "sweet spot" for females when it comes to mating in the Habronattus genus. Some courtship behaviors seen in the genus Habronattus include head bobbing, zigzag staggering motion, leg raising, palpi splaying, or no courtship at all. Other Habronattus jumping spiders have been observed producing vibrations to accompany their courtship displays. Males will mate with as many females as they can during their lives. Mating takes place during the spring and summer. (Elias, et al., 2005; Richmann and Cutler, 1998)
There is little known about the specific reproductive behavior of Salticidae. Mating and reproduction occur in the spring and summer in the family Salticidae. Jumping spider females collect their eggs in egg sacs, and the female keeps the egg sacs with her, guarding them while they hatch and for some time after. Related jumping spiders have been known to produce 6 egg sacs per year, each following clutch with fewer eggs. Other males of the family Salticidae have been observed to mature 2 weeks before female spiders; at this point the male guards the female until she matures and is ready to mate. (Guarisco, et al., 2001), but it is likely similar to other jumping spiders in the family
In many members of the family Salticidae, the female spider will guard her eggs for one month from predators and parasites until the young spiders emerge from the egg sac. After the young spiders disperse, the female parent provides no further care. (Guarisco, et al., 2001)
No lifespan has been described in the literature for, but generally jumping spiders do not survive in the wild longer than one year.
Jumping spiders have been shown in laboratory studies to learn and improve their hunting skills as they age. They learn to differentiate between types of prey through experience, as well as which prey items to avoid. Their visual acuity and ability to jump distances many times their size allows them to be efficient, effective predators. (Elias, et al., 2005)
Spiders have eight eyes, making vision one of their most important senses. Species of jumping spiders use their anterior median eye to detect movement, see shapes, and perceive color and depth. Visual cues are used to communicate during courtship, as the male does elaborate physical maneuvers while trying to attract the attention of the female. Males of some Habronattus spiders also produce seismic signals coordinated with the visual maneuvers during courtship. (Elias, et al., 2005; Guarisco, et al., 2001; Richman, 1981)
Jumping spiders consume live and dead invertebrates including fruit flies, mealworms, and meal moths, but live prey is preferred. (Guarisco, et al., 2001)
Jumping spiders in general have a broad range of predators including mammals, birds, lizards and other spiders. Some wasps prey heavily on jumping spiders. These wasps include muddaubers, organ-pipe muddaubers, and spider wasps. (Guarisco, et al., 2001)
is an important link in the food web. This jumping spider consumes smaller insects and other spiders, while it is consumed by larger organisms like mammals, lizards, birds, and other spiders and large insects.
The family Salticidae have both internal and external parasites. Internal parasites including nematode worms or acrocerid fly larvae. These internal parasites feed on the their host, but a majority of individuals die before emergence from the spider. External parasites include species of the family Mantispidae, that attach to a jumping spider and feed on blood. To complete its life cycle, the mantis-fly has to burrow itself into an egg sac of a female, meaning that mantis-fly species are both ectoparasites and eggsac parasites. (Guarisco, et al., 2001)

An animal that eats mainly insects or spiders.

A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.

"many forms." A species is polymorphic if its individuals can be divided into two or more easily recognized groups, based on structure, color, or other similar characteristics. The term only applies when the distinct groups can be found in the same area; graded or clinal variation throughout the range of a species (e.g. a north-to-south decrease in size) is not polymorphism. Polymorphic characteristics may be inherited because the differences have a genetic basis, or they may be the result of environmental influences. We do not consider sexual differences (i.e. sexual dimorphism), seasonal changes (e.g. change in fur color), or age-related changes to be polymorphic. Polymorphism in a local population can be an adaptation to prevent density-dependent predation, where predators preferentially prey on the most common morph.
