False widow spiders have become a common topic of conversation, sparking fear and curiosity. While these spiders aren't as dangerous as their infamous namesake, the black widow, knowing how to identify them is crucial for peace of mind. This guide provides a detailed look at how to spot a false widow, helping you differentiate it from other spiders and understand what to do if you encounter one.

What is a False Widow Spider?

The term "false widow" generally refers to spiders in the Steatoda genus. These spiders are often mistaken for black widows due to their similar appearance. However, their venom is significantly less potent. There are several species of false widows in the UK and other parts of the world, each exhibiting slight variations in appearance.

Key Characteristics of False Widow Spiders: A Visual Guide

Identifying a false widow requires careful observation. Here's what to look for:

Body Shape and Size:

Round abdomen: False widows have a noticeably round, often shiny abdomen.
Small size: Most are relatively small, with body lengths ranging from 5-15mm.
Legs: They possess relatively long and thin legs.

Color and Markings:

Dark brown or black: The body is usually dark brown or black.
Reddish or orange markings: The key differentiating feature is the variable reddish-orange markings on the abdomen. These markings aren't always distinct and can vary in shape and intensity. Note: the absence of these markings doesn't rule out a false widow identification.
Shiny appearance: The abdomen often has a shiny or glossy look.

What to Do if You Find a False Widow Spider

Most people experience only mild symptoms if bitten by a false widow, such as localized pain, swelling, and redness. However, if you are bitten, it’s best to follow these steps:

Clean the bite: Gently wash the area with soap and water.
Apply a cold compress: This can help reduce swelling and pain.
Monitor for symptoms: Keep an eye on the bite area for any signs of infection or worsening symptoms (increased pain, spreading redness, fever).
Seek medical attention: If you experience severe pain, difficulty breathing, or other concerning symptoms, seek medical advice immediately.
