Six-Spotted Fishing Spider, scientifically known as Dolomedes triton, is a fascinating member of the nursery web spider family (Pisauridae). As its name suggests, this wolf spider species specializes in hunting near bodies of water, such as streams, rivers, and ponds, which are abundant throughout Maine.

With a size that can reach up to two inches in length, the

Six-Spotted Fishing Spider is an impressive arachnid. Its long and slender legs allow it to gracefully move across the water’s surface, showcasing its excellent coordination and balance.

These spiders possess specialized hairs on their legs that enable them to detect vibrations caused by struggling insects on the water, instantly alerting them to potential prey. The

Six-Spotted Fishing Spider employs a unique hunting technique, utilizing the surrounding vegetation as a launching pad.

It lurks near the water’s edge and waits patiently for an unsuspecting insect to pass by. Once its prey comes within reach, this incredible spider lunges forward, capturing its victim with its powerful front legs.

Maine, a state renowned for its natural beauty and biodiversity, is not only home to the fascinating jumping spiders and wolf spiders but also boasts a variety of lesser-known spider species.

In this article, we will explore three intriguing spider species found in Maine: the

European Sheetweb Spider, the

Barn Orb Weaver Spider, and the

Northern Cupboard Spider.

European Sheetweb Spider


European Sheetweb Spider, scientifically known as Linyphia triangularis, is an intriguing arachnid that has found its way to the shores of Maine from its native Europe. These delicate spiders possess a unique appearance that sets them apart from other species inhabiting the region’s diverse ecosystems.

European Sheetweb Spiders derive their name from the intricate sheet-like webs they create. These sheetwebs are constructed horizontally and consist of silk strands interwoven into a flat, circular structure with a small tubular retreat located at one end.

The structure of these webs allows the spiders to capture their prey effectively. Once ensnared, the

European Sheetweb Spider ventures forth to immobilize its victims, meticulously wrapping them in silk before indulging in a well-deserved meal.

Barn Orb Weaver Spider


Barn Orb Weaver Spider, scientifically known as Araneus cavaticus, is a remarkable species found in a variety of habitats, including barns, sheds, and gardens. These spiders are known for their intricately woven orb-shaped webs, which can stretch to impressive sizes, capturing the attention of anyone who comes across them.

The webs of

Barn Orb Weaver Spiders are a sight to behold, crafted with exceptional precision and strength. These orb webs serve as both a home and a trap for prey.

Barn Orb Weaver Spiders position themselves strategically at the center of their webs, waiting for insects to fly into their sticky silken threads. Once ensnared, these spiders rapidly approach their prey and subdue them with a venomous bite.

The prey is then consumed, providing sustenance needed to support the spider’s growth and reproduction.

Northern Cupboard Spider


Northern Cupboard Spider, scientifically known as Steatoda borealis, is a lesser-known spider species found in Maine’s homes and buildings. Although often mistaken for the infamous black widow spider due to its appearance, the

Northern Cupboard Spider possesses distinct characteristics that set it apart.

With a dark brown or black coloration and a mottled pattern on its abdomen, the

Northern Cupboard Spider may strike an intimidating figure. However, unlike its venomous relative, its bite is relatively harmless to humans.

These spiders are adept at spinning irregular webs in undisturbed corners, cupboards, and basements, where they can lie in wait for unsuspecting prey. The web of the

Northern Cupboard Spider acts as a crucial tool in capturing its meals.

While their webs are not as extensive or elaborate as those of orb weavers, they are strategically positioned in areas with high insect activity. Once an insect becomes entangled in the web, the

Northern Cupboard Spider swiftly approaches, injecting its prey with venom to immobilize it.

Despite their presence in homes,

Northern Cupboard Spiders play a helpful role by controlling populations of unwanted pests. In conclusion, while jumping spiders and wolf spiders often steal the spotlight, it is essential not to overlook the diversity of lesser-known spider species that call Maine home.
