Nebraska is home to a diverse array of spider species, each with unique characteristics and roles in the ecosystem. Whether you’re a nature enthusiast, a homeowner concerned about pests, or just curious about the arachnids sharing your space, this list covers the most common and notable spiders found across the state. Learn how to identify them, understand their behaviors, and decide which ones are beneficial versus those you might want to manage around your home.
Orb-Weaver Spiders (Araneidae)
Orb-weavers are one of the most recognizable spider families, known for their beautiful, circular webs. In Nebraska, species like the Marbled Orb-Weaver (Araneus marmoreus) are common, particularly in gardens and wooded areas. They are harmless to humans and play a vital role in controlling flying insect populations, making them beneficial visitors to your yard.
Jumping Spiders (Salticidae)
Jumping spiders are small but highly active, characterized by their large front eyes and excellent vision. Species such as Phidippus audax are frequently seen on walls, windowsills, and plants. Their quick movements and distinctive eye patterns make them fascinating to observe, and they are generally harmless to people.
Wolf Spiders (Lycosidae)
Wolf spiders are robust, hairy hunters that do not spin webs but actively chase down prey. In Nebraska, they are often found in leaf litter, under rocks, or on the ground in open fields. While their size and appearance can be intimidating, wolf spiders are harmless and beneficial, as they help control pest insects.
Cellar Spiders (Pholcidae)
Commonly known as daddy long-legs, cellar spiders are often found in basements, garages, and sheds across Nebraska. They have long, delicate legs and small bodies. Despite their reputation, they pose no threat to humans and help manage other insect pests like mosquitoes and flies.
Brown Recluse (Loxosceles reclusa)
The brown recluse is a venomous spider occasionally sighted in Nebraska, especially in cluttered indoor spaces. Recognizable by its violin-shaped marking on the cephalothorax, it is important to exercise caution if you suspect its presence. While bites are rare, they can cause serious skin reactions, making identification and removal crucial.
Hobo Spider (Eratigena agrestis)
The hobo spider, once thought to be venomous, is now considered less dangerous but still warrants caution. It prefers dark, undisturbed areas like basements or crawl spaces. Its appearance is similar to other wolf spiders but with a more elongated body. Control measures focus on sealing entry points and reducing clutter.
Spined Micrathena (Micrathena gracilis)
This striking spider features a distinctive spined abdomen and vibrant coloration, often seen in Nebraska’s wooded areas during summer. They spin orb webs among trees and shrubs and are harmless to humans. Their unique appearance makes them a favorite among naturalists and photographers.
Grass Spiders (Agelenidae)
Grass spiders are fast-moving, funnel-web builders that live in tall grasses and weeds. They are common in Nebraska fields and gardens, where they help control insects like flies and moths. They are harmless and prefer to retreat into their funnel when disturbed.
Black Widow (Latrodectus mactans)
The black widow is one of Nebraska’s most infamous spiders, recognized by its shiny black body and distinctive red hourglass marking on the abdomen. They prefer dark, undisturbed areas like woodpiles and sheds. Despite their venomous bite, black widows are generally not aggressive and bites are rare, but caution is advised around their hiding spots.
How to Choose
When selecting or managing spiders in your environment, consider their role in pest control versus potential health risks. Identification is key—know which species are harmless and beneficial, and which might pose a threat. Also, evaluate your comfort level with spiders—if you prefer a pest-free home, focus on exclusion and removal of dangerous species like the brown recluse or black widow. Lastly, consider the habitat: maintaining clean, clutter-free spaces reduces hiding spots for unwanted spiders, while encouraging beneficial species to stay nearby.
