Geographic Range
Marpissa formosa
has been sighted in Minnesota, with possible sightings in Michigan, Ontario and Quebec.
Genus
Marpissa
has been found in Texas, Georgia, and North Carolina. It is suspected to be present
in Wisconsin as well. The majority of the genus is considered to be Great Lake endemics.
Habitat
The majority of individuals that have been sighted of
Marpissa formosa
have been located near freshwater bodies of water. Members of the genus have been
spotted in marshes and on cattails.
- Habitat Regions
- temperate
- terrestrial
- Terrestrial Biomes
- savanna or grassland
- Wetlands

- Other Habitat Features
- riparian
Physical Description
Marpissa formosa
has four sets of legs, with the first set being slightly shorter than the rest. They
have three pairs of spines located beneath the tibia. The abdomen of
Marpissa formosa
is marked with an angular central band. This genus is well-known for having short
bodies and a large set of eyes. Females of this species are dark brown, with a narrow
black band and occasionally some white scales. The first pair of legs are brown and
the rest are yellow. Males are a darker shade of brown with the narrow black band
with patches of white scales. Patches of black hairs surround the eyes.
- Other Physical Features
- ectothermic
- heterothermic
- bilateral symmetry
- Sexual Dimorphism
- female larger
- male more colorful
Development
There is little information available on the specific development of
Marpissa formosa
. Most jumping spider species are laid as eggs in the spring and summer, guarded by
the female. They hatch as spiderlings and remain under the protection of the female
until at least the first instar, usually for about a month. The young spiderlings
then leave the nest and disperse, to hunt and live independently. They go through
several molts before becoming adults capable of reproduction.

- metamorphosis
Reproduction
The genus
Marpissa
are dimorphic, with the males having conspicuous coloration to attract females. The
males will preform complex dances that are specific to each species of jumping spider.
The males will preform a variety of moves, from just the lifting of legs to bobbing,
twitching, zig zag motions, and flashing mouth parts. Some members of the genus are
able to produce audible sounds, such as a buzzing sound or a sound resembling a drum
roll. Females then choose their mates based on these elaborate courtship dances.
After mating,
Marpissa formosa
females will lay their eggs in silk tents made by males, guarding her eggs as well
as her newly hatched offspring.
- Key Reproductive Features
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- fertilization
- oviparous
Females of the genus
Marpissa
will guard their eggs and young offspring. After the young disperse, no more parental
care is provided.

Lifespan/Longevity
The lifespan of Marpissa formosa is unknown, but most jumping spiders do not live more than a year from birth to death.
Behavior
Marpissa formosa
moves around in quick, jerky movements. This genus does not spin webs for catching
prey, but rather builds small tent like structures in which they sit and wait for
prey. The genus
Marpissa
will stalk their prey until it is close enough for them to jump on it. The spider
will then lift their front legs and jump on its prey. The spider can jump over twice
the length of its body. They hunt primarily during the day because this is when their
eyesight is the strongest. Jumping spiders, including those in the genus
Marpissa
have been shown in laboratory settings to learn extensively from encounters with
prey. They learn to differentiate prey items, and their hunting skills grow as they
age.
- Key Behaviors
- terricolous
- saltatorial
- diurnal
- motile
- sedentary
Communication and Perception
Jumping spiders have exceptional eyesight. Their eight eyes allow for color vision,
motion detection, binocular vision, and high visual acuity. This allows for
Marpissa formosa
to navigate its environment, find mates, and locate prey mainly based on visual cues.
During courtship displays, males also communicate with females by making buzzing sounds
and another audible sounds that resembles a drum roll.
- Perception Channels
- visual
Food Habits
Maripossa formosa
is an insectivore and will sit and wait for prey to pass. These spiders will generally
take interest in what approaches them, but generally will feed on insects, including
web-building spiders, or other jumping spiders that are smaller than them in size.
The genus
Marpissa
is known to steal prey from the webs of spiders as well.
- Primary Diet
- carnivore
- Animal Foods
- insects
- terrestrial non-insect arthropods
Predation
There are no known predators of
Marpissa formosa
, but in general, jumping spiders are preyed upon by a wide variety of vertebrate
and invertebrate predators. These include mammals, birds, lizards, wasps, and other
spiders.
Ecosystem Roles
Marpissa formosa
is a predator of many other insect and spider species. These jumping spiders also
serve as prey to a variety of predators, including mammals, birds, and other spiders.
Economic Importance for Humans: Positive
Marpissa formosa
helps control other insect populations that may be considered nuisances to humans.
- Positive Impacts
- controls pest population
Economic Importance for Humans: Negative
There are no known adverse effects of Marpissa formosa on humans.
Conservation Status
Marpissa formosa
has no special conservation status.

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.
