Learn about these spiders to better identify them and appreciate their role in the local ecosystem.
1. Black Widow Spider (Latrodectus mactans)
The Black Widow is one of the most infamous spiders in Upstate NY, recognizable by its shiny black body and distinctive red hourglass marking on the underside of its abdomen. They prefer dark, undisturbed areas like woodpiles, sheds, and basements. While their venom can cause painful symptoms in humans, bites are rare and usually occur when the spider is accidentally provoked. They play a beneficial role by controlling pest insect populations.
2. Brown Recluse Spider (Loxosceles reclusa)
Although originally native to the Midwest, Brown Recluse spiders have occasionally been reported in Upstate NY, often as travelers or through shipments. They are small, about 1/4 inch long, with a characteristic violin-shaped marking on their back. Their bites can cause necrotic skin ulcers, but bites are infrequent because these spiders tend to be reclusive and non-aggressive. Identifying and avoiding them can prevent health issues.
3. Orb-Weaver Spiders (Araneidae family)
Orb-Weavers are among the most common garden spiders in Upstate NY, known for their beautiful, circular webs that shimmer in the sunlight. Species like the Garden Orb-Weaver (Araneus diadematus) are large, with distinctive markings resembling a white cross on their abdomen. They are harmless to humans and are beneficial for pest control, catching flies and moths in their webs.
4. Jumping Spiders (Salticidae family)
Jumping spiders are small, often colorful, and known for their impressive leaps and keen eyesight. They are commonly spotted on plants, walls, and windowsills. Their curious behavior and distinctive eye pattern make them easy to identify. These spiders are harmless and actively hunt smaller insects, making them beneficial in gardens and homes.
5. Woodlouse Hunter Spider (Dysdera crocata)
The Woodlouse Hunter is a reddish-brown spider with a large, curved chelicerae used for pinching woodlice and pillbugs. They are about 1/4 inch long and often found under rocks, logs, or inside sheds. Despite their intimidating appearance, they are harmless to humans and help control woodlouse populations, which can be pests in damp areas.
6. Yellow Garden Spider (Argiope aurantia)
The Yellow Garden Spider is famed for its striking black and yellow markings and large, orb-shaped web often found in gardens, fields, or along fences. Females are notably larger than males, with a body length reaching up to an inch. They pose no threat to humans and are vital for keeping pest insect numbers low in cultivated areas.
7. Wolf Spiders (Lycosidae family)
Wolf Spiders are robust, hairy spiders that often roam on the ground rather than spin webs, hence their name. They are typically gray or brown with distinctive markings and are commonly found in leaf litter, under rocks, or on lawns. They are non-aggressive and beneficial predators, helping control insects around homes.
8. Spiny Orb-Weaver (Araneus cavaticus)
This spider is notable for its spiny, bulbous body and vibrant coloration. They spin orb webs in shrubs and trees, especially in late summer and fall. They are harmless and contribute to local insect control, especially in wooded or gardened areas.
9. Hobo Spider (Eratigena agrestis)
The Hobo Spider, once thought to be a danger, is now considered less of a threat in Upstate NY. They are medium-sized, with a brownish appearance and a pattern of darker markings on their body. They prefer dark, undisturbed corners of basements, sheds, or garages. While their bites are rarely serious, it’s best to avoid disturbing them.
10. Cellar Spiders (Pholcidae family)
Often called Daddy Long Legs, Cellar Spiders are characterized by their long, thin legs and small bodies. They are common in basements, cellars, and garages, where they spin irregular, tangled webs. Despite their spooky appearance, they are harmless and help reduce populations of other insects, including mosquitoes and flies.
