Spiders are a set of arthropod animals of the Araneae order, very abundant throughout the world and about 45,000 different species are known. They are the most numerous order of the Arachnida class and are distantly related to other groups of arthropods, such as insects. It is also one of the most diverse groups, placing itself as regards the rest of organisms in seventh place with respect to their diversity. Spiders leave their eggs in a silk sack, where there may be about 100 eggs. These can be fixed to the surface, hidden in a net or carried by the female. The presence of sacks fixed inside a house indicates that soon there will be more spiders.

Types of common spiders in new jersey

actually, sadly, prevalent in NJ, black widows are considered the most venomous spider in North America. Their venom is reported to be 15 times stronger than a rattlesnake’s!


these are the most common spiders in all of North America – not just New Jersey. You’ll find triangulate cobweb spiders in garages and basements mostly.


these are not harmful and rarely bite unless provoked or agitated. Even if a grass spider did bite, it wouldn’t cause any harm anyway.


they don’t spin webs; instead, they chase and pounce on their insect prey like the wolves that inspired their name.


 these spiders prefer to build their messy webs on the interior and exterior of buildings and in sheds, stables, and barns.

cellar spiders prefer to hang upside down in their webs as they wait for prey, which typically consists of other spiders and insects.

 they actually do jump, and their natural habitats are grasslands, prairies, and open woodlands – including backyards.

Bold Jumping Spider (Phidippus Audax) found in the US and Canada

these guys are tiny but also super fast, which makes up for being so small.

much like their name suggests, these spiders are mostly found in orchards and are helpful in keeping other pests that could damage the trees and/or fruit away.

they jump by explosively straightening their back legs which are powered by the pressure created when blood is pumped into them from the body.

while common to homes, they are often not seen and therefore are good in our book.

 their excellent sense of sight comes from four pairs of large eyes. Golden jumping spiders also have three rows of eyes that help them to see what is all around them.

the bite of a shamrock spider can be painful, but it’s not dangerous for humans with effects comparable to a bee sting.

Araneus diadematus/European Garden Spider

they don’t make webs; rather, they build a sac or silken tube in protected places. And yellow sac spiders do have a nasty, painful bite!

 it’s sometimes called the pumpkin spider from the resemblance of the female’s inflated abdomen to an orange pumpkin.

 false widow spiders are often the subject of unflattering headlines, but in reality, they’re unlikely to bite humans.

during the day, these orbweaver spiders usually hide in a curled leaf near the edge of their web.

both species can be found in New Jersey yards and gardens throughout most of the year.

the markings on a cross orbweaver spider are very unique and actually quite pretty. You know – if you’re into that type of thing.

The Garden spider is the UK's most common orb web spider and is abundant in gardens, grassland and woodland - it can be found almost everywhere, in fact. It builds a 'typical' spider web (spirals with radial threads) out of sticky silk. It sits in the middle of the web, waiting to feel the vibrations of a struggling insect caught in the sticky threads. It then rushes out and wraps its prey tightly in silk. Once immobilised, it will kill its victim with a venomous bite. Adults appear from June to November and the young emerge from their silk egg-sac the following spring.

The Garden spider is one of the more easily recognised spiders. It is usually grey-brown or reddish-brown in colour, with a large white cross (made up of pale spots and streaks) on its abdomen. Females are twice the size of males.
