Meet the triangulate cobweb spider from the Steatoda genus! Found in places like North America, New Zealand, and Europe, this little spider has a neat triangular pattern on its back. On our page, you’ll discover interesting facts about this common house spider.
The egg sac is white and spherical made out of loosely woven silk. A female triangulate cobweb produces approximately six sacs throughout her lifetime and each of them contains about thirty small, round-shaped eggs.
The spiderlings remain in the web for some time post being hatched, after which they disperse.
Like other cobweb spiders, this species also spins an irregular, messy web in dark spaces of buildings alongside other human-made structures.
Yes, triangulate cobweb spiders have venom, but it’s mainly for catching their food. Their bites are not of medical importance, and because of their small size, their venom is non-toxic to humans.
They can bite if they feel threatened, but it’s usually mild and not harmful to humans. It might be a bit itchy or sore for a short time.
The triangulate cobweb spider plays a pivotal role in controlling the population of household pests. By preying on a variety of arthropods, including pillbugs, ticks, ants, and even dangerous spiders like the brown recluse and hobo spider, they act as natural pest managers. Their presence helps to maintain a balanced ecosystem within our homes, often going unnoticed.
Natural Predators: Despite their venomous defense, these spiders are preyed upon by larger predators, including birds, lizards, and larger spiders. Their stealthy behavior and tendency to reside in less-traveled corners help them avoid these threats.
Prey-Predator Dynamics: As predators, triangulate cobweb spiders help regulate the populations of their prey, contributing to the balance of the indoor ecosystem. Their webs are not just homes but also effective traps for various insects that wander into their territory.
Relationship with Humans: Triangulate cobweb spiders are often undervalued for the beneficial role they play in our homes. They are discreet creatures, typically avoiding human interaction and preferring to retreat rather than bite. Humans usually come across them when cleaning out seldom-disturbed areas of their homes.
| Other names | Triangulate bud spider |
| Lifespan | 1 to 3 years, though males live for a shorter span |
| Distribution | Throughout various parts of North America, Europe, New Zealand, and Southern Russia |
| Habitat | On windows and several dark, dingy, and dirty corners of buildings as well as other human-made structures |
| Diet | Pillbugs, ticks, arthropods, ants (like fire ants), as well as other spiders like the Brown recluse and Hobo |
In summary, the triangulate cobweb spider is a harmless, pest-controlling arachnid commonly found in undisturbed corners of indoor spaces.
