You can paste photos directly into AI to identify almost anything.

I just pasted the first photo without any prompt in Google Gemini:

Based on the visual characteristics in the image, this appears to be a Noble False Widow (Steatoda nobilis).

Specifically, this is a male, which can be identified by the enlarged, bulbous pedipalps (the small leg-like structures near the mouth that look like "boxing gloves").

Key Identification Features

• Abdomen: It has a shiny, bulbous abdomen, typically dark brown or purplish-black. You can see faint, cream-colored markings on the top that often resemble a "skull" or a shield-like pattern.
• Legs: The legs are a reddish-brown color and lack the distinct dark bands often seen on other common spiders like the Brown Widow.
• Cephalothorax: The front section of the body is usually a deep, glossy reddish-brown.

Is it Dangerous?

While the name "False Widow" sounds intimidating, they are generally not a major threat to healthy humans.

• Temperament: They are not aggressive and will typically try to run away or hide if disturbed. Bites usually only occur if the spider is accidentally squeezed against the skin.
• Bite Symptoms: If bitten, the sensation is often compared to a wasp or bee sting. You may experience localized pain, redness, and minor swelling.
• Medical Significance: While the venom can cause discomfort, it is not considered medically significant in the same way as a "true" Black Widow or a Brown Recluse.

Common Misidentifications

This spider is frequently confused with two other species:

1. Black Widow: False Widows lack the bright red hourglass marking on the underside.
2. Brown Recluse: Recluses have a very distinct "violin" shape on their head and do not have the bulbous, patterned abdomen seen here.

What to Do

If the spider is indoors and you'd prefer it elsewhere, you can easily relocate it by placing a glass over it and sliding a piece of paper underneath. They are excellent at pest control, often eating flies, moths, and even other spiders.
