Orange spiders are rare due to their color, so it is not every day we encounter a bright orange spider running across our roof.
However, uncommonly, there are species with a slight tinge of orange hue running down their body.
The marbled orb weaver is one of the only completely orange spiders native to the United States. Known for their spherical and globular orange heads and bodies, they can be considered rather cute for their size and color.
Today, we bring forth a concise list of 15 beautiful and remarkable orange spiders native to the United States of America.
And for all the people who love going that extra mile for information, we also have a list of spiders native to Florida!
Brownish-orange with white markings on their abdomen
Geographic location
California, Texas, and Florida
Some individuals exhibit an orange-brown color variant.
This orange hue can make these spiders particularly eye-catching when spotted in gardens or natural habitats.
They have mottled white markings on the dorsal abdomen. These markings form a distinctive cross pattern, making them easily identifiable among spider species.
Adult females vary in size, ranging from 6.5 to 20 mm in length, while males are generally smaller, measuring between 5.5 to 13 mm.
Like many other spiders, they display cannibalistic behavior, especially during or after sexual activity.
The upper side of the abdomen can be either white or yellow/orange, with both color variants species featuring black spots.
They feature six spine-like projections on the abdomen, giving them yet another stand-out look.
Females are larger, measuring 5–9 mm in length, while males are much smaller, ranging from 2 to 3 mm in length.
They have a relatively short lifespan, with individuals living only until they reproduce.
After producing an egg mass, females die, and males also have a limited lifespan, mostly surviving for six days after completing the sperm transfer to the female.
3) Tropical orb-weaver
Scientific Name
Eriophora ravilla
Size
9-24 mm
Identification
Reddish brown legs with white anterior and posterior sides.
Geographic location
North and South Carolina and Florida
They exhibit a range of color variations, with individuals varying from nearly white to nearly black. The females typically have a mostly reddish-brown cephalothorax and legs, with darker femora.
Typically found in open woodlands, including areas with live oak and hammocks. They are known for constructing large orb webs, which sometimes span over 1 meter across.
The bridge thread supporting the web can be exceptionally long, reaching up to 6 meters.
Individuals in Florida and more tropical regions display extensive color and pattern variation.
Displays sexual dimorphism in both size and color pattern.
Geographic location
Oregon, Utah, and Arizona
They have a striking orange-brown abdomen with two rows of small white-yellow spots. This unique color pattern makes the species relatively easy to identify, particularly females.
Not known to be aggressive towards humans and typically only bites in self-defense if handled roughly.
Females are among the largest non-tarantula spiders in North America, ranging from 24 mm to 40 mm in length when fully developed, while males are much smaller, measuring approximately 6 mm in length, with a simpler dark brown coloration.
Not extremely toxic to humans but pose little health concern to heal thy human adults and are better at controlling the insect population.
Hairy abdomen with light and dark brown hair sometimes appearing as orange.
Geographic location
Kansas, Indiana, and Louisiana
They show varied coloration throughout their body, the most observed coloration is a rusty-red or golden-orange body.
They often build their webs on buildings and other man-made structures, several feet above ground level.
Generally, a nocturnal species, they tend to hide in a curled leaf near the edge of their web during the day.
When provoked, they tend to bite but their venom poses no harm to humans.
The females lay their eggs in a sac made of their silk, which is hung near their web until the baby spiders hatch.
6) Pennsylvania Funnel-Web Spider
Scientific Name
Agelenopsis pennsylvanica
Size
7-14 mm
Identification
Solitary spider with funnel-shaped web
Geographic location
Washington, California, and Texas
They are not purely orange, but rather an amalgamation of darker and milder tones to help them get a better chance at survival!
They have dark markings on the carapace, along with yellow-orange and black patterns on the sternum and abdomen and a large V-shaped mark.
They are known for their unique web-building behavior.
They construct funnel-shaped webs typically located on the ground or in vegetation, hence their name.
They have a very intriguing yet not uncommon mating pattern where the females feed on the males.
These cannibalistic tendencies have proven to result in better-quality eggs.
7) Woodlouse spider
Scientific Name
Dysdera crocata
Size
9-15 mm
Identification
Shiny beige-yellow abdomen, usually found in warm places
Geographic location
Chicago, Miami, and Houston
Their abdomen is typically pale beige to yellow-brown, sometimes appearing dark grey with dark-red or tawny orange cephalothorax and legs.
They get their common name from the fact that they prey on woodlouse.
Though their prey has a tough exoskeleton, woodlouse spiders have large chelicerae that allow them to pierce the wood lice’s soft underbelly easily.
Their unique coloration has proved to be beneficial in terms of blending well with their habitat.
8) Arrowhead Orb-weaver
Scientific Name
Verrucosa arenata
Size
4-14 mm
Identification
While females have a characteristic triangle on their abdomen while it is absent in males
Geographic location
Nebraska and Texas
The abdomen color of this spider species can range from white to yellow/orange.
Orangish-yellow arrowhead spiders are more visible to prey and attract more prey, while white spiders, less visible, are dominant and have better living conditions.
Unlike most orb-weavers, who have globular abdomens Arrowhead orb-weavers have a very distinct triangular abdomen.
Another noticeable feature is their ability to construct an ‘invisible web’ which lacks radial threads.
They show sexual dimorphism, where the females have a prominent triangular abdomen while the males lack one.
9) Broad-Faced Sac Spider
Scientific Name
Trachelas tranquillus
Size
5-10 mm
Identification
Pale yellow abdomen with faint stripes on the dorsal side.
Geographic location
Iowa, North, and South Dakota, and Minnesota
They are not typically orange but the color of their abdomen can range from yellow to gray, thereby sometimes featuring an orange hue.
They have varied habitat preferences, sometimes found outdoors on foliage, other times under leaf litter, stones, and boards, and sometimes on buildings under windowsills and siding.
These spiders can deliver a painful bite, like a bite from a wasp or a bee.
There have been reported cases of secondary infection associated with their bite.
10) Bowl and Doily Spider
Scientific Name
Frontinella pyramitela
Size
4 mm
Identification
Their webs are in the shape of a dome
Geographic location
Kansas, Missouri, Iowa, and Minnesota
They are typically reddish-brown in color with more yellowish legs.
Under sunlight, the reddish-brown hue appears as a darker shade of orange.
Another distinct feature is their ability to construct an intricate sheet web consisting of an inverted dome-shaped web (the “bowl”) suspended on top of a horizontal sheet web (the “doily”).
Unlike many solitary spiders, these spiders tend to stay together.
Males from this species may stay with a female for extended periods beyond copulation.
They use sun rays to deplete their metabolic activity in order to focus more on reproduction.
Females have an inflated abdomen resembling a pumpkin
Geographic location
Washinton, Montana, North Dakota and Minnesota
Sometimes referred to as the “pumpkin spider” due to the resemblance of the female’s inflated abdomen to an orange pumpkin.
They exhibit a wide array of colorations and patterns. The most common color morph of them is an orange abdomen with brown to black markings.
They construct their orb-shaped web in places like trees, shrubs, tall weeds, and grasses in moist, wooded environments.
Their webs are equipped with a ‘signal’ thread to alert them of any prey.
12) Mabel Orchard Orb-weaver
Scientific Name
Leucauge argyrobapta
Size
3.5-7.5 mm
Identification
Long-jawed species of orb-weavers
Geographic location
Texas, New Mexico, Arizona, and Louisiana
One of the most common and beautiful species in eastern USA.
They have abdomens that feature dark mid-dorsal and reddish-orange triangular ventral areas and dorsolateral spots, creating an eye-catching coloration pattern.
They have a silvery-white appearance due to the presence of thin, platelet-like guanine crystals that reflect light.
They act as natural pest control, especially against mosquitoes and other disease-causing pests.
Besides having the same color, orange as the common ants, they have developed a fake thread waist creating an illusion of a third body segment while there are only two present.
They also can mimic the smell of ants by rubbing the formic acids secreted by ants against their body.
By mimicking the ants, they escape their common predators like wasps and birds that usually avoid ants.
14) Brilliant Jumping Spider
Scientific Name
Phidippus clarus
Size
3-4 mm
Identification
Distinct rectangular dorsal section
Geographic location
Florida, Oklahoma, Utah, and Nevada
While their coloration can vary from red/brown to lighter yellow or brown, the presence of orange hues with darker markings is what makes them stand out.
They prey on insects, other spiders, and various terrestrial arthropods.
Females produce well over 100 eggs per sac, with an average clutch containing approximately 135 eggs.
