New York’s diverse geography, from highly urban to fields, forests and mountains, makes for diversity among New York spiders.
While environmental factors influence the types of spiders found in New York, quick reflection on the fact that most New York back yards, whether in the New York city area or in the suburbs of Albany, Buffalo, Rochester or any other urban or suburban area, share very similar environments. Green grass, shrubs and trees make a nice habitat for many New York spiders that fall under the general heading home and garden spiders.
Except for the northern border, the state’s temperate climate means outdoor spider season lasts from early spring through late fall. Indoor spider season runs year round for some species.
In many instances, house spider management can be as easy as trimming the shrubs and tree branches around the yard to insure they do not touch the sides of the house. Many spiders found in the house tend to move from branches to walls to crevices in the walls and windows.
Cobweb spiders often define the common house spider category. New York homes often host the Triangulate House Spider and the Common House spider (Parasteatoda-tepidariorum), pictured at the top of the page. A couple of additional Stedota species go by the name False Widow spiders and they often wander indoors.
Grass spiders also known as funnel weavers, often wander inside the house. Outside the house, early morning dew often brings out their funnel webs in the yard. Tegenaria domestica, better known as a barn funnel weaver or domestic house spiders frequent indoor locations. Look for them especially in basement corners. Basements or cellars are also prime territory for the common cellar spider species.

Two additional groups of spiders, Orb Weavers and Jumping Spiders, often catch the average New Yorker’s eyes, along with the lens of the camera or cell phone. Initial checklists, including spider pictures, are presented below.
Checklist of New York Spiders: Orb Weavers
The following checklist of New York Spiders in the Orb Weaving family is preliminary. It is based on fifteen years of member contributions to Bugguide.
The list was created by searching Bugguide for New York spiders in the Orb Weavers Family (Araneidae). A total of 605 results over a fifteen year time span appeared. The results were placed on a spreadsheet that was then was sorted for duplicate species and genus only listings.
Results were the documenting of 39 Orb Weaving spider species in New York covering 15 genera.
One-third or 13 species were in genus Araneus. They are colorful orb weavers with distinct body patterns that often build webs in the back yard. The Humpbacked Orbweaver (Eustala anastera) is pictured at the top of the section.

Checklist: Jumping Spiders
Interestingly, a similar search on the Jumping Spiders of New York also took place, with 628 results gathered and placed on a spreadsheet.
After sorting for duplicates and genus only identifications, a total of 38 species divided into 24 genera were recorded. The list follows, including ten species with a picture.
The results follow a general spider identification trend witnessed by many researchers. While jumping spiders rank as one of the top two spider families in terms of total species, their small size and often dull appearance of the females makes for difficult field identification.
The picture at the top of the section shows Hentzia plamarun.
