49 Cool Spiders in Rhode Island

There are 49 different types of spiders in Rhode Island in this article including Orbweavers, Garden spiders, Black Widows, and more.

The wetlands, rolling hills, agricultural fields, and urban areas in Rhode Island make great homes for the various spiders that live in the state. With so many spiders it can be easy to confuse the different species for each other.

Identifying a spider can be done by examining its location, appearance, webbing, and behavior. Spiders are one of the world’s most feared animals, but the majority of them are not dangerous.

Let’s take a look at the spiders in Rhode Island. Here you will find useful information for not only the dangerous spiders in the state but the variety of harmless ones you may find.

Spiders in Rhode Island

1. Hentz Orbweaver 

• Experience Level: Intermediate
• Family: Araneidae 
• Scientific Name: Neoscona crucifera
• Other Names: Spotted orb weaver 
• Adult Size: 5 to 20 mm (0.19 to 0.78 inches) 
• Lifespan:  1 year
• Average Price Range: n/a

The Hentz orbweaver, also known as the spotted orbweaver, is most commonly found in the eastern regions of North America. Within the state of Rhode Island, the Hentz orbweaver can be found in habitats like woodlands, gardens, fields, parks, and even your own backyard.

Summer is the season these spiders are most active. They are nocturnal spiders but seeing them during the day is not unusual.

Hentz orbweavers can be found in a variety of colors like reddish brown, yellow-brown, or tan. Zigzag markings found on the abdomen of this species can be either dark and distinct or so light.

Their markings may be barely visible depending on the individual. A good way to identify this species is by the sections of dark red at the base of their legs. Like most spiders, females are larger than males and have more robust abdomens.

This species consumes a wide variety of insects like moths, flies, wasps, mosquitos, smaller spiders, and other small insects. If a female’s web breaks she will consume the damaged web and recycle the silk to create a stronger web to maximize prey-catching opportunities when food becomes scarce.

These spiders are not dangerous to humans and in fact, are great for gardens as they consume many garden pests.

2. Arabesque Orbweaver

• Experience Level: Intermediate
• Family: Araneidae 
• Scientific Name: Neoscona arabesca 
• Other Names: n/a 
• Adult Size: 5 to 7 mm (0.19 to 0.27 inches) 
• Lifespan:  1 year
• Average Price Range: n/a

Found all throughout the United States the arabesque orbweaver inhabits Rhode Island. They can be found in most habitats within the state but are most common in fields, woodlands, gardens, and grasslands.

Like other orb weavers, this species makes a vertical web that can be up to 2 feet in height. Females spend the majority of their life on their web while males are often found on the ground in search of a meal.

The arabesque orbweaver is commonly mistaken for other species like the spotted orbweaver or the furrow orbweaver. The best way to distinguish this species from others is by the markings on the abdomen.

Their abdomen typically has a colored vertical stripe down the middle with dark brown or black symmetrical spots on either side. This species of orb weaver is smaller than others and is usually found in brighter colors like red/orange, yellow, or shades of light brown.

Arabesque orbweavers have a diet consisting of many different small insects like beetles, flies, mosquitos, and moths. They will eat almost any small bug that crosses their path and is a great help for gardens.

Like all orb weavers, this species is not aggressive and bites from them are rare. When a bite does occur the symptoms are very mild and the bite itself is unlikely to be painful.

3. Furrow Orbweaver 

• Experience Level: Beginner 
• Family: Araneidae 
• Scientific Name: Larinioides cornutus
• Other Names: Furrow Orbweaver 
• Adult Size: 10 to 12 mm (0.39 to 0.47 inches
• Lifespan: 1 year 
• Average Price Range: n/a

The furrow orbweaver is found all across North America. In Rhode Island, this spider can be found in most habitats and often lives near humans in backyards, gardens, shrubs, and other nearby plant life.

They prefer to make webs in low vegetation near a water source like lakes, ponds, streams, and other moist areas. As all orb weavers do, this species builds circular vertical webs that can reach heights of over 2 feet.

The abdomen of furrow orbweavers is usually a shade of tan, brown, gray, or reddish brown with distinctive markings. The markings are down the center of the abdomen and are either dark brown or black with wavy edges.

While the legs and the cephalothorax have small hairs the abdomen remains smooth and hairless. The males of this species are very similar in size and color to females so it can be hard to identify the gender.

The furrow spider mainly consumes flying insects that get caught in its webs such as flies, mosquitos, gnats, moths, and more. These spiders usually eat their webs and rebuild them in the late evening and catch their prey at night.

Orb weavers are great to keep around because they eat tons of flying insects that are pests to humans and gardens. They are venomous however their venom is not dangerous to humans and is unlikely to cause any symptoms.

4. Cross Orbweaver 

• Experience Level: Intermediate
• Family: Araneidae 
• Scientific Name: Araneus diadematus
• Other Names: European garden spider 
• Adult Size: 5.5 to 20 mm (0.2 to 0.7 inches)

• Average Price Range: n/a

Also known as the European garden spider, the cross orbweaver can be found in many regions of North America including Rhode Island.

This species is common in many different habitats like meadows, fields, forests, gardens, hedgerows, and woodland clearings. They are also frequently spotted outside and inside buildings near light fixtures. Adults are most active and seen more frequently from summer to early autumn.

The cross orbweaver is usually found in shades of yellow, burnt orange, reddish brown, and dark gray. They can be identified by the white dots that form a cross on their abdomen.

Females are easy to distinguish due to their very large abdomen and extensive markings and fuzzy legs. Males are usually slightly smaller in length and have much smaller abdomens than females.

Like other orb weavers, the cross orbweaver is very beneficial to gardens and backyards because of their diet. They consume a variety of flying insects like moths, mosquitos, gnats, flies, and many more.

This species is not aggressive and is very unlikely to bite. A cross orbweavers bite is not dangerous and is less painful than a bee sting with little to no symptoms.

5. Giant Lichen Orbweaver

Most common in the eastern and midwestern states of the U.S. like Rhode Island is the giant lichen orbweaver. Like most orbweavers, this species can be found in habitats like woodlands, grasslands, meadows, gardens, and fields, although they prefer forest habitats.

They create large circular webs but unlike other orbweaver species, these spiders spend most of their time at the edge of the web rather than the center.

Giant lichen orbweavers are typically shades of light green, gray, black, orange, or white. Their abdomens are typically a greenish-gray color with white and black markings. They have a distinctive hump on their abdomen that can help distinguish them from other orbweavers.

This species’ legs are usually orange or white with thick black rings around them. Females are easy to identify due to their round robust abdomens. Males are usually noticeably smaller in size and have small skinny abdomens.

The giant lichen orbweaver is most active at night and they spend the majority of their time eating or fixing their webs. They like to hide during the day to avoid predators like birds, lizards, and other larger spiders. Their diet is mainly made up of flying insects like moths, flies, and wasps.

They are not an aggressive species and while they are venomous they’re not dangerous to humans and are unlikely to bite.

6. Marbled Orbweaver

Lined orbweavers live in highly vegetated areas, such as fields, gardens, and edged woodlands. The summer is when this spider is most active. The fall eggs are laid, hidden within folded leaves. Spiderlings hatch in the fall and overwinter until spring.

The lined orbweaver is a small species that is named after the lined markings that run vertically on its abdomen. Lined orbweavers have a cream, or greenish coloring on their legs and cephalothorax, which helps them blend into the habitats they live in.

Lined orbweavers have a white abdomen. The dorsal side of their abdomen has dark spots, and lines, while their underside has a mottled pattern of brown and yellow shades.

The bite of this spider is used to subdue small prey like gnats, flies, and mosquitoes. Their venom is harmless to humans, and due to their size, their fangs are usually too small to pierce human skin.

Brown in color, this spider’s shade ranges from light to dark. The abdomen of this species is what makes them easily identifiable, and also gives this spider its name.

Starbellied orbweavers have around 10 to 12 star-like points protruding from their abdomen, and two small points on their carapace. Males and females both showcase these small spikes, but males have smaller abdomens.

Starbellied orbweavers use their webs to catch insects like beetles, flies, moths, and other flying bugs. This spider is harmless to humans and rarely seen because of its nocturnal nature.

11. Spined Micrathena 

• Experience Level: Intermediate 
• Family: Araneidae 
• Scientific Name: Micrathena gracilis 
• Other Names: Spiny orb weaver
• Adult Size: 4 to 10 mm (0.15 to 0.31 inches) 
• Lifespan: 1 year 
• Average Price Range: n/a

The spined micrathena is most common in midwestern and eastern states in the U.S. and can be found in various habitats throughout Rhode Island. While these spiders are orb weavers and spin circular webs they do not repair them like most species of orbweavers.

Instead, the spined micrathena will build their webs and stay for a few days to a week and then move to a different location. They tend to live in habitats like hardwood forests that are near bodies of water like lakes, ponds, and lagoons.

Most spined micrathena have black legs and a black or dark reddish brown cephalothorax with a white abdomen that has black or dark brown thorn-like spikes sticking out.

The abdomen may also have small mottled yellow and black or white and black patches on either side. Like most spiders, the females of this species have much more bulbous abdomens while the males have flatter abdomens that contain fewer spikes.

Like most orbweavers, the spined micrathena has a diet consisting mainly of flying insects like moths, flies, gnats, and wasps. These spiders are not aggressive and are more likely to run away than bite a human. Their venom is not dangerous to humans and on rare occasions, they do bite it’s not painful and unlikely to cause symptoms.

12. White Micrathena 

• Experience Level: Intermediate 
• Family: Araneidae 
• Scientific Name: Micrathena mitrata 
• Other Names: Spiny orbweavers 
• Adult Size: 4.2 to 10.8 mm (0.16 to 0.42 inches)

• Average Price Range: n/a 

The white micrathena can be found in various habitats within Rhode Island and is common throughout the eastern regions of the United States. Typically found in woodland habitats this species prefers forests near small bodies of water like ponds, and lakes.

Unlike other orbweavers, these spiders build their circular webs horizontally rather than vertically. They are most active in the summertime but can be spotted from spring to fall.

White micrathena can be confused with the spined micrathena due to its similar abdomen and color. However, unlike the spined micrathena, the white micrathena only has four small, brown, or black thorn-like spines on the top of its abdomen.

This species has either a brown, red-brown, or black cephalothorax with a large white abdomen with dark-colored markings.

Because the white micrathena likes to live in moist areas near bodies of water their main source of food is small mosquitoes although they will eat other flying insects like gnats or small moths.

These spiders build large webs that can reach lengths of almost 7 feet. While their appearance can be off-putting these spiders are harmless and unlikely to bite a human.

13. Arrow-shaped Micrathena 

• Experience Level: Intermediate

They spin circular vertical webs that can reach up to 4 feet in height. Females rarely leave their webs while males can sometimes be found on trees and vegetation near their webs or even on the ground looking for food.

The arrow-shaped micrathena is easy to distinguish because of its bright colors and unique abdomen. Typically the cephalothorax of this species is a shade of red ranging from dark to very bright.

Their abdomen is a bright yellow with small black, brown, and red spots and two spikes on the end pointing in opposite directions with a third spike on the underside of the abdomen. These spikes are black with some mottled red at the base and very long.

These spiders look a lot more intimidating than they actually are. They are harmless to humans and would rather run and hide than try to bite someone.

Like other orbweaver species, the arrow-shaped micrathena mainly eats flying insects like mosquitoes, flies, wasps, and moths making them a beneficial spider to keep near your backyard or garden.

14. Arrowhead Spider
