17 Types of White Spiders With Pictures (Only #4 Is Mildly Poisonous)

White spiders are often seen on white or colored flowers. These spiders may seem atypical, but their white color acts as camouflage.

White spiders are more difficult for flies to spot whenever they approach flowers for pollen or nectar.

Goldenrod crab spiders are some of the most common white spiders are an example of white spiders that ambush prey, mainly by making the most of their camouflage-white coloring.

Are White Spiders Poisonous?

Most white spiders aren’t poisonous. They rarely bite and they might not be a common sight inside the house.

However, there are a few poisonous white spiders which means you should not handle some of the common white spider species found around parks and gardens.

Non-poisonous

Non-poisonous white spiders can still bite. Some of them are particularly prone to biting at night as they are nocturnal arachnids. These spiders mostly bite campers or those venturing out in nature.

Poisonous

A very small number of white spiders are poisonous. These aren’t deadly to humans, but their mildly-venomous nature inflicts pain and skin necrosis in the area of the bite.

The Northern Yellow Sac spider is one of the mildly-poisonous species known to bite without warning. Its bite is considered painful

Types of White Spiders

The following white spider species are common in North America. Some are native species while others have been accidentally introduced from other continents.

1. Spinybacked Orbweaver

Spinybacked Orbweaver

Scientific name: Gasteracantha cancriformis

Common name: Spinybacked Orbweaver

The Spinybacked Orbweaver is native to North America and parts of Central America. It’s one of the most common white spiders around homes.

Spiders of the genus are very common in gardens and around woodlands where they can be picked by hand.

The species isn’t venomous and it’s often found in shrubs or trees around homes, particularly next to citruses.

Spiders of this genus get their name from the 6 spines on their back. They improve the defensive techniques of the species.

Mostly white, this spider is known for its white dorsal with black spots.

Females are easier to spot since they measure up to 9mm, with the average female measuring around 7mm.

Male Spinybacked Orbweaver spiders are considerably smaller with an average size of 2mm.

Females spin orb-shaped spider webs where they catch all types of bugs and insects.

These spiders are generally seen as beneficial around homes as they routinely catch and eat mosquitoes, moths, and even beetles.

Female Spinybacked Orbweaver spiders can also eat larger flies. Females trap these large flies on the center spot of the weave, believed to be more robust when it comes to larger flies.

2. Goldenrod Crab Spider – White Spider with Red / Brown Dots

Goldenrod Crab Spider

Scientific name: Misumena vatia

Common name: Goldenrod Crab Spider, flower (crab) spider

Goldenrod Crab Spiders get their name from the sideways positioning of their legs which resemble the legs of crabs.

Spiders of this genus come in multiple colors but the pale yellow and white versions of the species are more common.

Makes tend to be seen in white coloring with pink lines more than females which are also white but which can also be pale yellow at times.

Both males and females have either red or pink lines along the sides of the body.

Spiders of this genus are known for their rather camouflage-like color as they sit on white or yellow flowers.

Unlike web-weaving spiders, Goldenrod Crab spiders don’t spin webs.

These spiders are predatory.

Goldenrod Crab spiders eat pollinator insects such as bees and wasps. They ambush them as they approach flowers for feeding.

One of the distinct traits of this species is the ability to alter its color.

Spiders of this genus can slightly change their color to appear white or golden depending on the flower they sit on.

This is their ultimate method of adapting camouflage to catch more pollinating insects.

3. Spined Micrathena

Spined Micrathena

Scientific name: Micrathena gracilis

Common name: Spined Micrathena, castleback orbweaver

The Spined Micrathena spider species gets its name from its reduced body size. Often overlooked, this small spider can sometimes be white.

Females and males of the species have a black and white body with black spines seen on the sides of their abdomen.

Female spiders are larger than males, growing to a maximum size between 7 and 10mm.

Male Spined Mucrathena spiders grow to a size between 4.5 and 5mm.

While small, the SPined Micrathena spider can still catch insects larger than its body size.

For this reason, it spins wheel-shaped spider weaves which are seen in dense shrubs or around trees to catch various insects.

This spider web is typically positioned vertically, as with all orbweaver species.

Spined Micrathena spiders can be seen around this spider web all day.

Spiders of this genus are active from spring to late October.

They overwinter as eggs and emerge late in the season, just as summer begins.

4. Northern Yellow Sac Spider – Poisonous White Spider in House

Northern Yellow Sac Spider

Scientific name: Cheiracanthium mildei

Common name: Northern Yellow Sac Spider

The Northern Yellow Sac spider is the name of multiple similar spider species living in Africa, Asia, and North America.

Their camouflage coloring is used when sitting on flowers and looking for insects to prey on.

American Green Crab spiders eat bees and beetles. They are also seen eating larger prey such as butterflies.

Mating is a complex process for the species.

Females lay eggs in a sack and they remain close to it for a while before dying.

Spiderlings hatch a few days later as miniature adults.

As their name implies, the species has legs that resemble the legs of crabs.

This allows them to move sideways easier.

The forelegs of the species are long and they resemble crab legs the most.

These spiders resemble crabs in their leg movements.

The front legs of the White-banded Crab spider are longer. These pairs of legs are used to pin down prey.

White-banded Crab spiders don’t spin spider webs.

Mating competition between male White-banded Crab spiders is high.

This is one of the few spider species where an adult male guards a female until sexual maturity is reached so they can mate.

Both males and females can be seen on white or yellow flowers.

It can take a few days for this spider to change its color from white to yellow or from yellow to white.

This is achieved by their monochrome pigments.

15. Green-legged Orbweaver

Green-legged Orbweaver

Scientific name: Mangora maculata

Common name: Green-legged Orbweaver

The Green-legged Orbweaver gets its name from the green colors of its legs. It has dark green legs and a white dorsal.

The white dorsal of the spider is known for also having green spots making this species similar to the Marbled orbweaver in coloring patterns.

The Green-legged Orbweaver is a species where females are larger than males. Both can build spider webs but females build larger webs.

Mating typically occurs on the spider web for this species. Male spiders approach the web and make their way to the center point where the female is.

The male tries to move without causing too many spider web vibrations as it may end up being eaten by the female.

Other males prefer female luring tactics for mating. The male builds a smaller spider web next to the web of the female.

Males then connect a silk line between the spider webs and start to vibrate their small webs to attract the female for mating.

Both the male’s and the female’s spider webs are barely visible or not visible to insects that get caught up in them as prey.

16. Kidney Garden Spider

Kidney Garden Spider

Scientific name: Bijoaraneus mitificus

The Kidney Garden spider is mostly white. It’s an orbweaver which means it spins an orb-shaped web.

This species is characterized by its white and green coloring. Its abdomen is white while its head and legs are green.

Females are larger than males.

Female Kidney Garden spiders grow up to 9mm while males grow up to 5mm.

Known for their bulbous abdomens, these are spiders known for building complex webs.

Spiders don’t sit in the center of the web as they prefer to build a smaller cocoon-like web nearby.

Female spiders build the largest webs.

Males also build webs. However, the webs of males are smaller and typically found next to larger female webs.

These webs are very common in gardens. You can find them in shrubs, among flowers, or in dense plants such as lemongrass.

These spiders are known for always sitting next to their spider webs, just in case, any insect gets trapped in them.

They are tied to the web with a thin silk line. Spiders can’t be seen as they either hide in a smaller web or a curled leaf.

Spiders always come out whenever their webs vibrate. This is the signal an insect has been trapped in the web.

All webs are restored at night if damaged during the day.

17. Australian Golden Orbweaver – White Spider With Red Legs

Australian Golden Orbweave
