Quick Answer
It is possible to identify a black widow without seeing its colors, as it has a distinctive body shape and a red or orange hourglass shape on its abdomen, but in a non-colored context, this becomes less visible.
Inspecting the Body Shape
To identify a black widow without seeing its colors, inspect the body shape. The black widow’s body is approximately 1/4 inch long and 1/2 inch wide. It has a glossy, black body with a rounded abdomen and a more pointed cephalothorax. The abdomen also tends to be slightly larger than the cephalothorax. When inspecting the body shape, note any slight indentations or notches on the abdomen.
Looking for Leg Spots
Another characteristic to look for is the leg spots. Black widows have a series of small, white or light-colored spots on their legs. These spots are usually in a symmetrical pattern and may be more visible if the spider is viewed from the side. Count the number of spots, as most black widows have three spots on each leg. This can help confirm the spider’s identity.
Understanding the Behavior
In a non-colored context, observing the spider’s behavior can be a good indicator of its identity. Black widows are generally more docile and less aggressive than other spiders. However, they are also more likely to attack when threatened. If the spider appears to be relatively calm and is not immediately attacking, it may be a black widow.
