This guide covers mainly spiders of the eastern U.S. and Canada.  Exceptions are the arctic spiders that arachnologist Roy Erling Wrånes photographed in Finnmark County in far northern Norway; he has given me permission to use these photos on the website, but he owns the copyrights.  They are grouped by their families with the other spiders.

All spiders are venomous, but in the U.S. and Canada, only the Brown Recluse  and the Black Widow  are known to do serious harm to humans via their venom.  The Brown Recluse, also called the "violin spider" because of a charactertistic dark marking on its cephalothorax, is often found indoors in old houses not protected by pest control and is most common in the south central part of the U.S.  Black Widows are generally found outside.  The tarantulas of the Southwestern U.S. sometimes bite in self-defense and can toss spine-like hairs at their attackers.  The North American Funnel Web Spiders (members of the Agelenidae family) should not be confused with the highly venomous Sydney (Australia) Funnel Web Spiders (Atrax robustus), which are members of another suborder altogether (the Mygalomorphae). 

Spiders have a cephalothorax (literally "head-neck") and an abdomen, unlike insects, which have distinct divisions between the head, thorax and abdomen.  Also, unlike insects, spiders have eight legs and chelicerae and lack antennae and wings (which some insects do lack).  They also have spinnerets on their abdomens.  Most have eight eyes, although some have fewer; spider eye arrangements can be key to distinguish spider families and sometimes genera, as shown by Lynette Elliott's Spider Eye Arrangement Page on BugGuide.  Lynette generalized these patterns from spider photos on that site.  Links to the applicable family eye arrangement information are shown below with the photos shown for each spider family.  I have included this because it is the clearest attempt to demonstrate one of the rules by which spiders are classified. 

Spiders have some natural insect enemies.  One of the most unusual of them is an insect: the so-called thread-legged bug of the Stenolema genus.  These bugs wiggle constantly, and when they contact a spider web, the spider mistakes them for prey.

However, other spiders can inflict painful nips under some circumstances.  I once was surprised in Florida by a large wolf spider that had crawled into my shoe when I put it on; it left two small, relatively deep indendations in my callused big toe.

There is one endangered North Carolina spider species, i.e., the Spruce Fir Moss Spider.   As the name implies, the spider's natural habitat is found in the Southern Appalachians, among these northern conifers, at elevations above ~5400 feet.

John and Jane Balaban provided many identifications (not all specified below), especially of crab spiders, on their own initiative, which we checked out.  We accept responsibility for the correctness of these IDs.

In any case, feel free to contact us.

Purseweb Spiders (Atypidae family, Mygalomorphae suborder)

Mygalomorphs are generally large spiders; though they seem to be the species most likely to inspire arachnophobia, the bites of all of the US species are harmless to humans.  "True tarantulas" (family Theraphosidae) are members of this suborder, while the spiders in this family are also called "atypical tarantulas" as well as "purseweb spiders." There are two genera in the US:  Atypus and Sphodros.

Common Orb Weavers (Araneidae family, Araneoidea superfamily, Entelegynae, Araneomorphae infraorder)

Araneus Genus Eye Arrangement (Elliott): This seems very similar to the eye arrangements of other Araneidae family members to me.  However, to see close-up photos of eye arrangements of the Araneidae family, go halfways down the page of Spider Eye Arrangements (Elliott)

Spinning mainly vertical flat, spiral-patterned webs ("orbs") is characteristic of most these spiders, but it is not the most important taxonomically.  Arachnologists consider anatomical structure and behavior to be more important than web characteristics, as exemplified by Willey and Johnson (1992).

Spined Orb Weavers (Micrathena genus, Araneidae family, Araneoidea, Orbiculariae, Entelegynae, Araneomorphae)

These orb weavers have traditionally been considered to be in this family, and I'm betting it will be official in the final classification scheme.  But their genus seems not to have come up for consideration yet.

Micrathena gracilis

These spiders, commonly known as Spined Micrathenas, have eight black spines on a mostly white abdomen.

Spined Micrathena (Micrathena gracilis), Durham, 7/28/05. This spider had spun a web across a walking path in my neighborhood that was high enough not to be disturbed by people.  Spined Micrathena  (Micrathena gracilis), Riverbend Park, Catawba County, 9/24/09 Male Spined Micrathena (Micrathena gracilis), Third Fork Creek Trail, Curham, NC, 7/4/12.  ID thanks to John and Jane Balaban.

Micrathena mitrata

These spiders have just two spines on their abdomens.  ID based on remarks about this species near the bottom of the Micrathena Gracilis page of the University of Arkansas' Arthropod Museum Notes.

Micrathena mitrata, Penny's Bend Nature Preserve, Durham County, NC, 9/7/07. Chatham County, NC, 11/9/05.  This one was about ¼ inch long. Orb weaver (Micrathena mitrata), Durham, NC, 10/3/13 Micrathena mitrata, ventral view.  Riverbend Park, Catawba County, NC, 9/24/09

This spider was in the process of web-spinning. Another Arrow-shaped Micrathena spider Eno River SP, Old Cole Mill Road access, 7/30/05.

Crablike Spined Orb Weavers (Gasteracantha cancriformis, Araneidae family, Araneoidea superfamily,  Entelegynae, Araneomorphae infraorder)

These spiders may look like crabs, but they feel like sandspurs if you have the wrong kind of encounter with them.  Perhaps because birds have learned to avoid them, they often feel free to spin their webs across trails.

Triangulate Orb Weaver, White Pines Nature Preserve, Chatham County, NC, 9/25/05.

Araneus genus members (Araneidae family, Araneoidea, Entelegynae, Araneomorphae infraorder)

Araneus and Neoscona are very similar genera, and many of these photos were not taken at an angle that reveals the one tiny difference (the posterior dorsal longitudinal groove), as described at American Museum of Natural History's Orb Weaver Page.  So many of these are guesses.

Marbled Orb Weavers (Araneus marmoreus)

These pictures illustrate the variation in abdominal patterns occuring among members of this species.

Yellow-and-black Garden Spider (Argiope aurantia)

These are some of the biggest spiders in eastern North America; not including their legs, they can reach one inch in length.  As a result, they are also the most familiar outdoor spiders, though far from the most common.

Basilica Spiders (Mecynogea lemniscata, Araneidae family, Araneoidea superfamily, Entelegynae, Araneomorphae infraorder)

In contrast with the flat webs of the orchard spiders, the webs of most of these spiders fill a three-dimensional space and no two threads seem to be in the same plane.  They often are found in groups in contiguous webs.  Maybe they get their common name from this web structure.   They do not weave orb-shaped webs; Willey, Johnson and Adler  say that although some have argued that they should be assigned to the Linyphiidae family on the basis of similarity of web construction; giving greater weight to anatomical structure and behavior as critera led to their Araneidae classification.  This illustrates another problem with common names: orb-weaving is not a universal Araneidae trait.

The two pictures on the left (second row) suggest an aborted courtship (Durham, 7/20/05).  It took place within one of a group of complex webs with elaborate three-dimensional structures.  All webs were apparently spun by spiders of the same species, which had the abdominal patterns pictured in the two photos on the right.

Long-jawed Orb Weavers (Tetragnatha genus)

These spiders are so named because of their unusually large chelicerae, ending in fangs, which contain venom-producing glands ending in hollow spikes through which they deliver their venom.

Theridiidae Eye Arrangement (Elliott)

These spiders spin cobwebs, which humans detest and songbirds love to use for nesting material.   These webs are small and compact, eventually becoming frayed and indistinct, and probably not especially effective in catching flying insects.  But they frequently catch insects crawling up the sides of houses.

Spider (Anelosimus studiosus), Durham, NC, 1/1/23          

Widow Spiders (Latrodectus genus members) use a neurotoxic venom.   They are outdoor spiders; some are reclusive, while others appear out in the open.  It is unusual to see a male; they are much smaller and very different in appearance.   These spiders are venomous at every age.  It is best to be observant.

Southern Black Widow (Latrodectus mactans)

The characteristic marking is a red hourglass (really two opposing triangles fused) on the ventral side of the abdomen.  There are no red markings on the dorsal side.

Adult female Southern Black Widow?, Zebulon, NC.  Photo taken by and provided by Cindy Privette.  Species ID uncertain because the red hourglass figure is partially obstructed.

Northern Black Widow (Latrodectus variolus)

The characteristic marking is a divided red hourglass figure on the ventral side of the abdomen.  The dorsal side typically has three or more red spots.

Linyphiidae Eye Arrangement (Elliott)

All photos in the first row were taken of members of the species Florinda coccinea,  subfamily Linyphiinae member, according to Wikipedia's Blacktailed Red Sheetweaver page and Samford University's Florinda coccinea page.   Levi and Levi (2002) describe this species as yellow-colored (rather puzzling) and most commonly found in the southeastern US. 

This spider family has the most species, although its members are very tiny and probably overlooked altogether by most people.  The two shown below are apparently the most common in Piedmont North Carolina.

Black-tailed Red Sheetweavers (Florinda coccinea)

These spiders usually spin their webs, in the form of horizontal sheets, near the ground in grasses.

Bowl-and-doily Spiders (Frontinella communis)

These spiders have typically showed up in the branches of small trees.  Their webs have two parts, one that is bowl-shaped and another below it that is disk-shaped and looks like a doily.  When prey lands on the "doily," the spider leaps down from the "bowl" and attacks it.

Funnel Web Spiders and Grass Spiders (Agelenidae family, Other Amaurobioids, RTA Clade, Entelegynae, Araneomorphae infraorder)  

Agelenidae Eye Arrangements (Elliott)

Funnel web spiders have a two-part web consisting of a horizontal sheet which catches prey and a funnel-shaped tunnel in which the spider hides.   In this way, these harmless (to humans) spiders bear a superficial resemblance to the highly venomous Sydney (Australia) Funnel-web Spiders, members of the Hexathelidae family, suborder Mygalomorphae.   This is a classic example of how common names can cause serious confusion, not the least because web shape is a relatively unimportant spider classification factor.

On our deck, funnel web spiders spin horizontal webs that attach at one end to large round lights, curving partially around them across to the "funnel" end of the web.  Moths drawn to the light find themselves trapped in the web because the web partially blocks their departure from the light.  The web isn't sticky and sometimes moths find their way out.  Yet sometimes the spider is faster, jumping up to bite a flying moth, which lands on the web.  Since these lights are such a recent development in natural history, these spiders' strategic use of them looks a lot like human-like engineering reasoning.  But spiders don't even have real brains: a single ganglion (a bundle of nerves) serves instead.

Grass spiders (Agelenopsis genus) are small and very common, often seen running along the ground.

In general, it is not possible to identify definitively the species of individual Agelenopsis genus spiders with only a dorsal view.

The infamous Hobo Spider (Tegenaria agrestis), found in the western US, is a member of this family, but not easy to identify.  There is some controversy about their having a dangerous bite, but clear scientific evidence remains to be produced.  Some points of view: https://www.arachnology.org/Arachnology/Pages/Hobo.html.

The spiders in this row are seen in summer mode, catching prey out in the open:

Funnel web spider?  Eno River State Park, Old Cole Mill Road access, 5/10/07, ventral view.  The light color suggests that it's a recent molt.

We know less about how funnel web spiders function in the winter, but this group of spiders, in the Barronopsis genus, hid in white cocoon-like enclosures beneath the bark of a rotting tree, but they are much tougher than moth cocoons and probably do an excellent job of protecting spiders from cold.

These spiders are noted both for their ability to walk on water and for their spiderlings, which stay together until relatively large.  Their only use of silk is to build their "nursery webs."

Jumping Spiders (Salticidae family, Dionycha, RTA Clade, Entelegynae, Araneomorphae infraorder)

Salticidae Eye Arrangements (by Lynette Elliot)

Jumping spiders seem to have excellent vision and quick response times.  One thing that's obvious is that they (except those in the Synemosyninae subfamily) can make big moves, such as 180° complete turnabouts, almost instantaneously, and don't need to have a completely horizontal surface to do it, either!  They pounce on prey rather than using webs to catch it.

Notes on Taxonomy Choices

Generally speaking, spider taxonomy is based on anatomical structure characteristics and nature of behavior, e.g., the movements a spider makes while constructing a web, with final web shape a lesser consideration.  Some spiders ambush and pounce on prey rather than catching it in a web.  This is based on the theoretical heredity pattern on certain traits during the process of evolution.  Nevertheless, certain families have misleading common names, e.g., "orb weavers."

Spider taxonomy today, now basically on spider genome data, is a work in progress: although the family, genus and species classifications shown below are mainly traditional, the higher taxa are in the process of substantial revision and different sources seem to represent different stages of the process.  We have done our best to make sense of this situation and are trying to keep as current as possible.  

Family classifications (thanks to the Global Biodiversity Information System) are provided by:   Catalogue of Life      Species 2000      World Spider Catalog.

We have chosen the Tree of Life Web spider pages to supply the higher taxa shown here: we should note, however, that all or most of its web pages used here are marked "temporary page."  The Tree of Life Web does not supply taxa under the Araneidae family:  for this, we have used Animal Diversity Web Araneidae pages.  Since the number of levels in the developing hierarchy is still under consideration, none are assigned names such as "superfamily."  The classifications below represent their trees in a simplified form to show the relationships among the members of this small subset of (mainly North Carolina) spider species, with taxa at the head of each family category presented from lowest to highest in the hierarchy.    For details on where this process was in 1999, see Griswold et al., 1999.
