Spiders in Columbus, Ohio, have a very diverse area to call home. Columbus isn’t a quiet, small town, but it is filled with parks and museums. The Scioto Mile that runs on either side of the Scioto River is a vast park filled with trails and an interactive fountain. The Museum of Art is a breathtaking place, including a unique and fun sculpture garden, then on the west bank of the river is the COSI Science Center. No matter where you go in Columbus, there is plenty of beauty to take in, along with tons of fun things to do.

Since Columbus is such a diverse area for a spider, if you happened to be one, there would be unlimited places to call home. Parks running next to rivers are filled with insect life. With plenty of dinner options for a spider, the spiders can’t resist easy and moderately risky dining. Let’s take a look at a fraction of the cool spiders one might find in the city of Columbus.

Common Spiders

1. Bolas Spider (Mastophora hutchinsoni)

Appearance: These are rare orb weavers that have large, round, irregularly shaped abdomens and small heads. They are light beige or white with brown growth-looking bumps on their back and chalky, marbling over the surface.

Size: Females are 10 – 20 mm, while the much smaller males are only 2 mm

Habitat: Plants, shrubs, trees or any foliage where they can sit and wait for a moth to come near the sticky ball.

Behavior: These interesting spiders do not make webs but instead make fishing lines with a sticky ball on the end that they use to catch insects. They produce pheromones mimicking a noctuid moth and once moths searching for a mate show up, the spider swings the sticky ball and catches the moth.

Dangers: None

2. Black and Yellow Garden Spider (Argiope aurantia)

Appearance: Light yellow to beige with dark reddish brown chelicerae and feet.

Size: Both sexes are approximately the same size of .20 – .39 inches long.

Habitat: Gardens, bushes, trees, leaf litter, forest floors, trees

Behavior: These spiders are nocturnal hunters that do so on foot and do not make a web. Most of the bites inflicted upon humans happen because the spider is in clothing or bedding and gets pinned up against the skin.

Dangers: Their bite is painful as the cytotoxic venom begins to work through your system. Neurotoxic venom is stronger. At first, the bite is similar to a mosquito bite, but as time passes, the bite becomes more painful with burning and swelling and can lead very rarely to mild necrosis of the skin.

27. Mediterranean Recluse (Loxosceles rufescens)

Appearance: They look almost identical to the brown recluse though these originated in the Mediterranean and tend to live in caves. The violin shape at the top of its cephalothorax is there, just like on the brown recluse.

Size: .25 inches long with a leg span of

Habitat: Caves, basements, and tunnels

Behavior: They are nocturnal hunters, doing so on foot and hunting silverfish, roaches, and small insects. They spin very small, sloppy webs that they use for sleeping and egg sacs.

Dangers: Similar to the brown recluse, this spider injects a cell-destroying venom that is not felt at first but after 2 – 8 hours because very painful and swollen. It can become necrotic like the brown recluse’s bite, though it is milder. The center of the bite will deflate and become dark blue first. In rare cases, hemolysis, intravascular coagulation, and thrombocytopenia can occur, leading to renal failure.

28. Northern Black Widow (Latrodectus various)

Northern Black Widow - Black Spiders in Florida

There are several different types of widow spiders in the world.

©Porco_Rosso/Shutterstock.com

Appearance: A black pea-sized spider with two red spots on the underside of its abdomen. This is referred to as a broken hourglass and is sometimes missing the middle section, and other times it appears just as two red dots. The males have brown legs and have sets of white bands along each side of their abdomen. Juveniles of both sexes can have white banding.

Size: Females are .31 – .5 inches long with a leg span of 1 – 1.37 inches long. The males are .11 – .4 inches long with a leg span of .51 inches.

Habitat: Manmade structures like houses, garages, attics, walls, cabinets, wood piles, playhouses, boxes, and outdoor toy bins. They are very timid and stay hidden almost always.

Behavior: Because of their timid disposition, the spiders stay hidden in crevices or small undisturbed spaces most of the time. They make small, sloppy cobweb spiderwebs for catching small insects.

Dangers: There is less than 1% mortality of people bitten, and those are generally small children. The female spider releases a neurotoxic venom when she bites. The amount of toxin varies depending on when she last used it. The venom of a black widow is 15 times stronger than rattlesnake venom. The bite causes severe pain, swelling, severe cramping, fever, nausea, sweating, and chills, just to name a few. However, even if a typical person doesn’t seek antivenom or medical attention, the bite typically goes away in a few days. The pain and other negative symptoms will last that long without antivenom if the spider releases a big load of venom in her bite.

29. Southern Black Widow (Latrodectus mactans)

Appearance: A black pea-sized spider with an hourglass marking on the underside of its abdomen. Males do not have the hourglass shape but can have red spots on the underside of their abdomen.

Size: Females are .5 inches long and up to 1.47 – 1.9 inches with a leg span, while males are .23 inches long with a leg span of .39 inches.

Habitat: Manmade structures like houses, garages, attics, walls, cabinets, wood piles, playhouses, boxes, and outdoor toy bins.

Behavior: They are very timid and stay hidden almost always.

Dangers: There is less than 1% mortality of people bitten, and those are generally small children. Approximately 2,500 people visit emergency centers every year with black widow bites and are treated with antivenom. Without the antivenom, the side effects will last several days. Since the black widow’s bite releases neurotoxic venom, it causes systemic effects like severe pain, nausea, chills, profuse sweating, fever, severe muscle cramping, and more. If not treated with antivenom, the person generally recovers in a couple of days unless they are very young, old, or have a severely compromised immune system.

30. Brown Recluse (Loxosceles reclusa)

Appearance: Darker brown legs and violin shape on the head area of the cephalothorax. The violin’s neck points towards its rear end. The cephalothorax is round and light brown or beige, like the abdomen. They have very fine hairs on their legs. They also only have six eyes as opposed to the eight of most other spiders.

Size: 1/4 – 1/2 inches long and a 1 inch leg span

Habitat: Gaps under boards, wood piles, rocks, leaf litter, or other first debris. They are also found in outdoor buildings, in boxes, or other small spaces without human traffic. They are not found throughout the country and are mostly in the central states.

Behavior: They are nocturnal hunters that do so on foot without the assistance of a web. They are known to be cannibalistic and to also eat dead insects.

Dangers: They are very timid spiders and bite only as a last resort.
